 ### Added - spf13/afero for Filesystem Abstraction
 - **New `internal/fs` package** for testable filesystem operations
 - **In-memory filesystem** for unit testing without disk I/O
 - **Global FS interface** that can be swapped for testing:
  ```go
  fs.SetFS(afero.NewMemMapFs())  // Use memory
  fs.ResetFS()                    // Back to real disk
  ```
 - **Wrapper functions** for all common file operations:
  - `ReadFile`, `WriteFile`, `Create`, `Open`, `Remove`, `RemoveAll`
  - `Mkdir`, `MkdirAll`, `ReadDir`, `Walk`, `Glob`
  - `Exists`, `DirExists`, `IsDir`, `IsEmpty`
  - `TempDir`, `TempFile`, `CopyFile`, `FileSize`
 - **Testing helpers**:
  - `WithMemFs(fn)` - Execute function with temp in-memory FS
  - `SetupTestDir(files)` - Create test directory structure
 - **Comprehensive test suite** demonstrating usage
 ### Changed
 - Upgraded afero from v1.10.0 to v1.15.0
 ## [3.42.33] - 2026-01-14 "Exponential Backoff Retry"
 ### Added - cenkalti/backoff for Cloud Operation Retry
 - **Exponential backoff retry** for all cloud operations (S3, Azure, GCS)
 - **Retry configurations**:
  - `DefaultRetryConfig()` - 5 retries, 500ms→30s backoff, 5 min max
  - `AggressiveRetryConfig()` - 10 retries, 1s→60s backoff, 15 min max
  - `QuickRetryConfig()` - 3 retries, 100ms→5s backoff, 30s max
 - **Smart error classification**:
  - `IsPermanentError()` - Auth/bucket errors (no retry)
  - `IsRetryableError()` - Timeout/network errors (retry)
 - **Retry logging** - Each retry attempt is logged with wait duration
 ### Changed
 - S3 simple upload, multipart upload, download now retry on transient failures
 - Azure simple upload, download now retry on transient failures
 - GCS upload, download now retry on transient failures
 - Large file multipart uploads use `AggressiveRetryConfig()` (more retries)
 ## [3.42.32] - 2026-01-14 "Cross-Platform Colors"
 ### Added - fatih/color for Cross-Platform Terminal Colors
 - **Windows-compatible colors** - Native Windows console API support
 - **Color helper functions** in `logger` package:
  - `Success()`, `Error()`, `Warning()`, `Info()` - Status messages with icons
  - `Header()`, `Dim()`, `Bold()` - Text styling
  - `Green()`, `Red()`, `Yellow()`, `Cyan()` - Colored text
  - `StatusLine()`, `TableRow()` - Formatted output
  - `DisableColors()`, `EnableColors()` - Runtime control
 - **Consistent color scheme** across all log levels
 ### Changed
 - Logger `CleanFormatter` now uses fatih/color instead of raw ANSI codes
 - All progress indicators use fatih/color for `[OK]`/`[FAIL]` status
 - Automatic color detection (disabled for non-TTY)
 ## [3.42.31] - 2026-01-14 "Visual Progress Bars"
 ### Added - schollz/progressbar for Enhanced Progress Display
 - **Visual progress bars** for cloud uploads/downloads with:
  - Byte transfer display (e.g., `245 MB / 1.2 GB`)
  - Transfer speed (e.g., `45 MB/s`)
  - ETA prediction
  - Color-coded progress with Unicode blocks
 - **Checksum verification progress** - visual progress while calculating SHA-256
 - **Spinner for indeterminate operations** - Braille-style spinner when size unknown
 - New progress types: `NewSchollzBar()`, `NewSchollzBarItems()`, `NewSchollzSpinner()`
 - Progress bar `Writer()` method for io.Copy integration
 ### Changed
 - Cloud download shows real-time byte progress instead of 10% log messages
 - Cloud upload shows visual progress bar instead of debug logs  
 - Checksum verification shows progress for large files
 ## [3.42.30] - 2026-01-09 "Better Error Aggregation"
 ### Added - go-multierror for Cluster Restore Errors
 - **Enhanced error reporting** - Now shows ALL database failures, not just a count
 - Uses `hashicorp/go-multierror` for proper error aggregation
 - Each failed database error is preserved with full context
 - Bullet-pointed error output for readability:
  ```
  cluster restore completed with 3 failures:
  3 database(s) failed:
    • db1: restore failed: max_locks_per_transaction exceeded
    • db2: restore failed: connection refused
    • db3: failed to create database: permission denied
  ```
 ### Changed
 - Replaced string slice error collection with proper `*multierror.Error`
 - Thread-safe error aggregation with dedicated mutex
 - Improved error wrapping with `%w` for error chain preservation
 ## [3.42.10] - 2026-01-08 "Code Quality"
 ### Fixed - Code Quality Issues
 - Removed deprecated `io/ioutil` usage (replaced with `os`)
 - Fixed `os.DirEntry.ModTime()` → `file.Info().ModTime()`
 - Removed unused fields and variables
 - Fixed ineffective assignments in TUI code
 - Fixed error strings (no capitalization, no trailing punctuation)
 ## [3.42.9] - 2026-01-08 "Diagnose Timeout Fix"
 ### Fixed - diagnose.go Timeout Bugs
 **More short timeouts that caused large archive failures:**
 - `diagnoseClusterArchive()`: tar listing 60s → **5 minutes**
 - `verifyWithPgRestore()`: pg_restore --list 60s → **5 minutes**
 - `DiagnoseClusterDumps()`: archive listing 120s → **10 minutes**
 **Impact:** These timeouts caused "context deadline exceeded" errors when
 diagnosing multi-GB backup archives, preventing TUI restore from even starting.
 ## [3.42.8] - 2026-01-08 "TUI Timeout Fix"
 ### Fixed - TUI Timeout Bugs Causing Backup/Restore Failures
 **ROOT CAUSE of 2-3 month TUI backup/restore failures identified and fixed:**
 #### Critical Timeout Fixes:
 - **restore_preview.go**: Safety check timeout increased from 60s → **10 minutes**
  - Large archives (>1GB) take 2+ minutes to diagnose
  - Users saw "context deadline exceeded" before backup even started
 - **dbselector.go**: Database listing timeout increased from 15s → **60 seconds**
  - Busy PostgreSQL servers need more time to respond
 - **status.go**: Status check timeout increased from 10s → **30 seconds**
  - SSL negotiation and slow networks caused failures
 #### Stability Improvements:
 - **Panic recovery** added to parallel goroutines in:
  - `backup/engine.go:BackupCluster()` - cluster backup workers
  - `restore/engine.go:RestoreCluster()` - cluster restore workers
  - Prevents single database panic from crashing entire operation
 #### Bug Fix:
 - **restore/engine.go**: Fixed variable shadowing `err` → `cmdErr` for exit code detection
 ## [3.42.7] - 2026-01-08 "Context Killer Complete"
 ### Fixed - Additional Deadlock Bugs in Restore & Engine
 **All remaining cmd.Wait() deadlock bugs fixed across the codebase:**
 #### internal/restore/engine.go:
 - `executeRestoreWithDecompression()` - gunzip/pigz pipeline restore
 - `extractArchive()` - tar extraction for cluster restore
 - `restoreGlobals()` - pg_dumpall globals restore
 #### internal/backup/engine.go:
 - `createArchive()` - tar/pigz archive creation pipeline
 #### internal/engine/mysqldump.go:
 - `Backup()` - mysqldump backup operation
 - `BackupToWriter()` - streaming mysqldump to writer
 **All 6 functions now use proper channel-based context handling with Process.Kill().**
 ## [3.42.6] - 2026-01-08 "Deadlock Killer"
 ### Fixed - Backup Command Context Handling
 **Critical Bug: pg_dump/mysqldump could hang forever on context cancellation**
 The `executeCommand`, `executeCommandWithProgress`, `executeMySQLWithProgressAndCompression`, 
 and `executeMySQLWithCompression` functions had a race condition where:
 1. A goroutine was spawned to read stderr
 2. `cmd.Wait()` was called directly
 3. If context was cancelled, the process was NOT killed
 4. The goroutine could hang forever waiting for stderr
 **Fix**: All backup execution functions now use proper channel-based context handling:
 ```go
 // Wait for command with context handling
 cmdDone := make(chan error, 1)
 go func() {
    cmdDone <- cmd.Wait()
 }()
 select {
 case cmdErr = <-cmdDone:
    // Command completed
 case <-ctx.Done():
    // Context cancelled - kill process
    cmd.Process.Kill()
    <-cmdDone
    cmdErr = ctx.Err()
 }
 ```
 **Affected Functions:**
 - `executeCommand()` - pg_dump for cluster backup
 - `executeCommandWithProgress()` - pg_dump for single backup with progress
 - `executeMySQLWithProgressAndCompression()` - mysqldump pipeline
 - `executeMySQLWithCompression()` - mysqldump pipeline
 **This fixes:** Backup operations hanging indefinitely when cancelled or timing out.
 ## [3.42.5] - 2026-01-08 "False Positive Fix"
 ### Fixed - Encryption Detection Bug
 **IsBackupEncrypted False Positive:**
 - **BUG FIX**: `IsBackupEncrypted()` returned `true` for ALL files, blocking normal restores
 - Root cause: Fallback logic checked if first 12 bytes (nonce size) could be read - always true
 - Fix: Now properly detects known unencrypted formats by magic bytes:
  - Gzip: `1f 8b`
  - PostgreSQL custom: `PGDMP`
  - Plain SQL: starts with `--`, `SET`, `CREATE`
 - Returns `false` if no metadata present and format is recognized as unencrypted
 - Affected file: `internal/backup/encryption.go`
 ## [3.42.4] - 2026-01-08 "The Long Haul"
 ### Fixed - Critical Restore Timeout Bug
 **Removed Arbitrary Timeouts from Backup/Restore Operations:**
 - **CRITICAL FIX**: Removed 4-hour timeout that was killing large database restores
 - PostgreSQL cluster restores of 69GB+ databases no longer fail with "context deadline exceeded"
 - All backup/restore operations now use `context.WithCancel` instead of `context.WithTimeout`
 - Operations run until completion or manual cancellation (Ctrl+C)
 **Affected Files:**
 - `internal/tui/restore_exec.go`: Changed from 4-hour timeout to context.WithCancel
 - `internal/tui/backup_exec.go`: Changed from 4-hour timeout to context.WithCancel  
 - `internal/backup/engine.go`: Removed per-database timeout in cluster backup
 - `cmd/restore.go`: CLI restore commands use context.WithCancel
 **exec.Command Context Audit:**
 - Fixed `exec.Command` without Context in `internal/restore/engine.go:730`
 - Added proper context handling to all external command calls
 - Added timeouts only for quick diagnostic/version checks (not restore path):
  - `restore/version_check.go`: 30s timeout for pg_restore --version check only
  - `restore/error_report.go`: 10s timeout for tool version detection
  - `restore/diagnose.go`: 60s timeout for diagnostic functions
  - `pitr/binlog.go`: 10s timeout for mysqlbinlog --version check
  - `cleanup/processes.go`: 5s timeout for process listing
  - `auth/helper.go`: 30s timeout for auth helper commands
 **Verification:**
 - 54 total `exec.CommandContext` calls verified in backup/restore/pitr path
 - 0 `exec.Command` without Context in critical restore path
 - All 14 PostgreSQL exec calls use CommandContext (pg_dump, pg_restore, psql)
 - All 15 MySQL/MariaDB exec calls use CommandContext (mysqldump, mysql, mysqlbinlog)
 - All 14 test packages pass
 ### Technical Details
 - Large Object (BLOB/BYTEA) restores are particularly affected by timeouts
 - 69GB database with large objects can take 5+ hours to restore
 - Previous 4-hour hard timeout was causing consistent failures
 - Now: No timeout - runs until complete or user cancels
 ## [3.42.1] - 2026-01-07 "Resistance is Futile"
 ### Added - Content-Defined Chunking Deduplication
 **Deduplication Engine:**
 - New `dbbackup dedup` command family for space-efficient backups
 - Gear hash content-defined chunking (CDC) with 92%+ overlap on shifted data
 - SHA-256 content-addressed storage - chunks stored by hash
 - AES-256-GCM per-chunk encryption (optional, via `--encrypt`)
 - Gzip compression enabled by default
 - SQLite index for fast chunk lookups
 - JSON manifests track chunks per backup with full verification
 **Dedup Commands:**
 ```bash
 dbbackup dedup backup <file>              # Create deduplicated backup
 dbbackup dedup backup <file> --encrypt    # With encryption
 dbbackup dedup restore <id> <output>      # Restore from manifest
 dbbackup dedup list                       # List all backups
 dbbackup dedup stats                      # Show deduplication statistics
 dbbackup dedup delete <id>                # Delete a backup manifest
 dbbackup dedup gc                         # Garbage collect unreferenced chunks
 ```
 **Storage Structure:**
 ```
 <backup-dir>/dedup/
  chunks/           # Content-addressed chunk files (sharded by hash prefix)
  manifests/        # JSON manifest per backup
  chunks.db         # SQLite index for fast lookups
 ```
 **Test Results:**
 - First 5MB backup: 448 chunks, 5MB stored
 - Modified 5MB file: 448 chunks, only 1 NEW chunk (1.6KB), 100% dedup ratio
 - Restore with SHA-256 verification
 ### Added - Documentation Updates
 - Prometheus alerting rules added to SYSTEMD.md
 - Catalog sync instructions for existing backups
 ## [3.41.1] - 2026-01-07
 ### Fixed
 - Enabled CGO for Linux builds (required for SQLite catalog)
 ## [3.41.0] - 2026-01-07 "The Operator"
 ### Added - Systemd Integration & Prometheus Metrics
 **Embedded Systemd Installer:**
 - New `dbbackup install` command installs as systemd service/timer
 - Supports single-database (`--backup-type single`) and cluster (`--backup-type cluster`) modes
 - Automatic `dbbackup` user/group creation with proper permissions
 - Hardened service units with security features (NoNewPrivileges, ProtectSystem, CapabilityBoundingSet)
 - Templated timer units with configurable schedules (daily, weekly, or custom OnCalendar)
 - Built-in dry-run mode (`--dry-run`) to preview installation
 - `dbbackup install --status` shows current installation state
 - `dbbackup uninstall` cleanly removes all systemd units and optionally configuration
 **Prometheus Metrics Support:**
 - New `dbbackup metrics export` command writes textfile collector format
 - New `dbbackup metrics serve` command runs HTTP exporter on port 9399
 - Metrics: `dbbackup_last_success_timestamp`, `dbbackup_rpo_seconds`, `dbbackup_backup_total`, etc.
 - Integration with node_exporter textfile collector
 - Metrics automatically updated via ExecStopPost in service units
 - `--with-metrics` flag during install sets up exporter as systemd service
 **New Commands:**
 ```bash
 # Install as systemd service
 sudo dbbackup install --backup-type cluster --schedule daily
 # Install with Prometheus metrics
 sudo dbbackup install --with-metrics --metrics-port 9399
 # Check installation status
 dbbackup install --status
 # Export metrics for node_exporter
 dbbackup metrics export --output /var/lib/dbbackup/metrics/dbbackup.prom
 # Run HTTP metrics server
 dbbackup metrics serve --port 9399
 ```
 ### Technical Details
 - Systemd templates embedded with `//go:embed` for self-contained binary
 - Templates use ReadWritePaths for security isolation
 - Service units include proper OOMScoreAdjust (-100) to protect backups
 - Metrics exporter caches with 30-second TTL for performance
 - Graceful shutdown on SIGTERM for metrics server
 ---
 ## [3.41.0] - 2026-01-07 "The Pre-Flight Check"
 ### Added - 🛡️ Pre-Restore Validation
 **Automatic Dump Validation Before Restore:**
 - SQL dump files are now validated BEFORE attempting restore
 - Detects truncated COPY blocks that cause "syntax error" failures
 - Catches corrupted backups in seconds instead of wasting 49+ minutes
 - Cluster restore pre-validates ALL dumps upfront (fail-fast approach)
 - Custom format `.dump` files now validated with `pg_restore --list`
 **Improved Error Messages:**
 - Clear indication when dump file is truncated
 - Shows which table's COPY block was interrupted
 - Displays sample orphaned data for diagnosis
 - Provides actionable error messages with root cause
 ### Fixed
 - **P0: SQL Injection** - Added identifier validation for database names in CREATE/DROP DATABASE to prevent SQL injection attacks; uses safe quoting and regex validation (alphanumeric + underscore only)
 - **P0: Data Race** - Fixed concurrent goroutines appending to shared error slice in notification manager; now uses mutex synchronization
 - **P0: psql ON_ERROR_STOP** - Added `-v ON_ERROR_STOP=1` to psql commands to fail fast on first error instead of accumulating millions of errors
 - **P1: Pipe deadlock** - Fixed streaming compression deadlock when pg_dump blocks on full pipe buffer; now uses goroutine with proper context timeout handling
 - **P1: SIGPIPE handling** - Detect exit code 141 (broken pipe) and report compressor failure as root cause
 - **P2: .dump validation** - Custom format dumps now validated with `pg_restore --list` before restore
 - **P2: fsync durability** - Added `outFile.Sync()` after streaming compression to prevent truncation on power loss
 - Truncated `.sql.gz` dumps no longer waste hours on doomed restores
 - "syntax error at or near" errors now caught before restore begins
 - Cluster restores abort immediately if any dump is corrupted
 ### Technical Details
 - Integrated `Diagnoser` into restore pipeline for pre-validation
 - Added `quickValidateSQLDump()` for fast integrity checks
 - Pre-validation runs on all `.sql.gz` and `.dump` files in cluster archives
 - Streaming compression uses channel-based wait with context cancellation
 - Zero performance impact on valid backups (diagnosis is fast)

 # dbbackup: The Real Open Source Alternative
 ## Killing Two Borgs with One Binary
 You have two choices for database backups today:
 1. **Pay $2,000-10,000/year per server** for Veeam, Commvault, or Veritas
 2. **Wrestle with Borg/restic** - powerful, but never designed for databases
 **dbbackup** eliminates both problems with a single, zero-dependency binary.
 ## The Problem with Commercial Backup
 | What You Pay For | What You Actually Get |
 |------------------|----------------------|
 | $10,000/year | Heavy agents eating CPU |
 | Complex licensing | Vendor lock-in to proprietary formats |
 | "Enterprise support" | Recovery that requires calling support |
 | "Cloud integration" | Upload to S3... eventually |
 ## The Problem with Borg/Restic
 Great tools. Wrong use case.
 | Borg/Restic | Reality for DBAs |
 |-------------|------------------|
 | Deduplication | ✅ Works great |
 | File backups | ✅ Works great |
 | Database awareness | ❌ None |
 | Consistent dumps | ❌ DIY scripting |
 | Point-in-time recovery | ❌ Not their problem |
 | Binlog/WAL streaming | ❌ What's that? |
 You end up writing wrapper scripts. Then more scripts. Then a monitoring layer. Then you've built half a product anyway.
 ## What Open Source Really Means
 **dbbackup** delivers everything - in one binary:
 | Feature | Veeam | Borg/Restic | dbbackup |
 |---------|-------|-------------|----------|
 | Deduplication | ❌ | ✅ | ✅ Native CDC |
 | Database-aware | ✅ | ❌ | ✅ MySQL + PostgreSQL |
 | Consistent snapshots | ✅ | ❌ | ✅ LVM/ZFS/Btrfs |
 | PITR (Point-in-Time) | ❌ | ❌ | ✅ Sub-second RPO |
 | Binlog/WAL streaming | ❌ | ❌ | ✅ Continuous |
 | Direct cloud streaming | ❌ | ✅ | ✅ S3/GCS/Azure |
 | Zero dependencies | ❌ | ❌ | ✅ Single binary |
 | License cost | $$$$ | Free | **Free (Apache 2.0)** |
 ## Deduplication: We Killed the Borg
 Content-defined chunking, just like Borg - but built for database dumps:
 ```bash
 # First backup: 5MB stored
 dbbackup dedup backup mydb.dump
 # Second backup (modified): only 1.6KB new data!
 # 100% deduplication ratio
 dbbackup dedup backup mydb_modified.dump
 ```
 ### How It Works
 - **Gear Hash CDC** - Content-defined chunking with 92%+ overlap detection
 - **SHA-256 Content-Addressed** - Chunks stored by hash, automatic dedup
 - **AES-256-GCM Encryption** - Per-chunk encryption
 - **Gzip Compression** - Enabled by default
 - **SQLite Index** - Fast lookups, portable metadata
 ### Storage Efficiency
 | Scenario | Borg | dbbackup |
 |----------|------|----------|
 | Daily 10GB database | 10GB + ~2GB/day | 10GB + ~2GB/day |
 | Same data, knows it's a DB | Scripts needed | **Native support** |
 | Restore to point-in-time | ❌ | ✅ Built-in |
 Same dedup math. Zero wrapper scripts.
 ## Enterprise Features, Zero Enterprise Pricing
 ### Physical Backups (MySQL 8.0.17+)
 ```bash
 # Native Clone Plugin - no XtraBackup needed
 dbbackup backup single mydb --db-type mysql --cloud s3://bucket/
 ```
 ### Filesystem Snapshots
 ```bash
 # <100ms lock, instant snapshot, stream to cloud
 dbbackup backup --engine=snapshot --snapshot-backend=lvm
 ```
 ### Continuous Binlog/WAL Streaming
 ```bash
 # Real-time capture to S3 - sub-second RPO
 dbbackup binlog stream --target=s3://bucket/binlogs/
 ```
 ### Parallel Cloud Upload
 ```bash
 # Saturate your network, not your patience
 dbbackup backup --engine=streaming --parallel-workers=8
 ```
 ## Real Numbers
 **100GB MySQL database:**
 | Metric | Veeam | Borg + Scripts | dbbackup |
 |--------|-------|----------------|----------|
 | Backup time | 45 min | 50 min | **12 min** |
 | Local disk needed | 100GB | 100GB | **0 GB** |
 | Recovery point | Daily | Daily | **< 1 second** |
 | Setup time | Days | Hours | **Minutes** |
 | Annual cost | $5,000+ | $0 + time | **$0** |
 ## Migration Path
 ### From Veeam
 ```bash
 # Day 1: Test alongside existing
 dbbackup backup single mydb --cloud s3://test-bucket/
 # Week 1: Compare backup times, storage costs
 # Week 2: Switch primary backups
 # Month 1: Cancel renewal, buy your team pizza
 ```
 ### From Borg/Restic
 ```bash
 # Day 1: Replace your wrapper scripts
 dbbackup dedup backup /var/lib/mysql/dumps/mydb.sql
 # Day 2: Add PITR
 dbbackup binlog stream --target=/mnt/nfs/binlogs/
 # Day 3: Delete 500 lines of bash
 ```
 ## The Commands You Need
 ```bash
 # Deduplicated backups (Borg-style)
 dbbackup dedup backup <file>
 dbbackup dedup restore <id> <output>
 dbbackup dedup stats
 dbbackup dedup gc
 # Database-native backups
 dbbackup backup single <database>
 dbbackup backup all
 dbbackup restore <backup-file>
 # Point-in-time recovery
 dbbackup binlog stream
 dbbackup pitr restore --target-time "2026-01-12 14:30:00"
 # Cloud targets
 --cloud s3://bucket/path/
 --cloud gs://bucket/path/
 --cloud azure://container/path/
 ```
 ## Who Should Switch
 ✅ **From Veeam/Commvault**: Same capabilities, zero license fees  
 ✅ **From Borg/Restic**: Native database support, no wrapper scripts  
 ✅ **From "homegrown scripts"**: Production-ready, battle-tested  
 ✅ **Cloud-native deployments**: Kubernetes, ECS, Cloud Run ready  
 ✅ **Compliance requirements**: AES-256-GCM, audit logging  
 ## Get Started
 ```bash
 # Download (single binary, ~48MB static linked)
 curl -LO https://github.com/PlusOne/dbbackup/releases/latest/download/dbbackup_linux_amd64
 chmod +x dbbackup_linux_amd64
 # Your first deduplicated backup
 ./dbbackup_linux_amd64 dedup backup /var/lib/mysql/dumps/production.sql
 # Your first cloud backup  
 ./dbbackup_linux_amd64 backup single production \
  --db-type mysql \
  --cloud s3://my-backups/
 ```
 ## The Bottom Line
 | Solution | What It Costs You |
 |----------|-------------------|
 | Veeam | Money |
 | Borg/Restic | Time (scripting, integration) |
 | dbbackup | **Neither** |
 **This is what open source really means.**
 Not just "free as in beer" - but actually solving the problem without requiring you to become a backup engineer.

 9. Create new base backup
 ```
 ## Large Database Support (600+ GB)
 For databases larger than 600 GB, PITR is the **recommended approach** over full dump/restore.
 ### Why PITR Works Better for Large DBs
 | Approach | 600 GB Database | Recovery Time (RTO) |
 |----------|-----------------|---------------------|
 | Full pg_dump/restore | Hours to dump, hours to restore | 4-12+ hours |
 | PITR (base + WAL) | Incremental WAL only | 30 min - 2 hours |
 ### Setup for Large Databases
 **1. Enable WAL archiving with compression:**
 ```bash
 dbbackup pitr enable --archive-dir /backups/wal_archive --compress
 ```
 **2. Take ONE base backup weekly/monthly (use pg_basebackup):**
 ```bash
 # For 600+ GB, use fast checkpoint to minimize impact
 pg_basebackup -D /backups/base_$(date +%Y%m%d).tar.gz \
  -Ft -z -P --checkpoint=fast --wal-method=none
 # Duration: 2-6 hours for 600 GB, but only needed weekly/monthly
 ```
 **3. WAL files archive continuously** (~1-5 GB/hour typical), capturing every change.
 **4. Recover to any point in time:**
 ```bash
 dbbackup restore pitr \
  --base-backup /backups/base_20260101.tar.gz \
  --wal-archive /backups/wal_archive \
  --target-time "2026-01-13 14:30:00" \
  --target-dir /var/lib/postgresql/16/restored
 ```
 ### PostgreSQL Optimizations for 600+ GB
 | Setting | Value | Purpose |
 |---------|-------|---------|
 | `wal_compression = on` | postgresql.conf | 70-80% smaller WAL files |
 | `max_wal_size = 4GB` | postgresql.conf | Reduce checkpoint frequency |
 | `checkpoint_timeout = 30min` | postgresql.conf | Less frequent checkpoints |
 | `archive_timeout = 300` | postgresql.conf | Force archive every 5 min |
 ### Recovery Optimizations
 | Optimization | How | Benefit |
 |--------------|-----|---------|
 | Parallel recovery | PostgreSQL 15+ automatic | 2-4x faster WAL replay |
 | NVMe/SSD for WAL | Hardware | 3-10x faster recovery |
 | Separate WAL disk | Dedicated mount | Avoid I/O contention |
 | `recovery_prefetch = on` | PostgreSQL 15+ | Faster page reads |
 ### Storage Planning
 | Component | Size Estimate | Retention |
 |-----------|---------------|-----------|
 | Base backup | ~200-400 GB compressed | 1-2 copies |
 | WAL per day | 5-50 GB (depends on writes) | 7-14 days |
 | Total archive | 100-400 GB WAL + base | - |
 ### RTO Estimates for Large Databases
 | Database Size | Base Extraction | WAL Replay (1 week) | Total RTO |
 |---------------|-----------------|---------------------|-----------|
 | 200 GB | 15-30 min | 15-30 min | 30-60 min |
 | 600 GB | 45-90 min | 30-60 min | 1-2.5 hours |
 | 1 TB | 60-120 min | 45-90 min | 2-3.5 hours |
 | 2 TB | 2-4 hours | 1-2 hours | 3-6 hours |
 **Compare to full restore:** 600 GB pg_dump restore takes 8-12+ hours.
 ### Best Practices for 600+ GB
 1. **Weekly base backups** - Monthly if storage is tight
 2. **Test recovery monthly** - Verify WAL chain integrity
 3. **Monitor WAL lag** - Alert if archive falls behind
 4. **Use streaming replication** - For HA, combine with PITR for DR
 5. **Separate archive storage** - Don't fill up the DB disk
 ```bash
 # Quick health check for large DB PITR setup
 dbbackup pitr status --verbose
 # Expected output:
 # Base Backup: 2026-01-06 (7 days old) - OK
 # WAL Archive: 847 files, 52 GB
 # Recovery Window: 2026-01-06 to 2026-01-13 (7 days)
 # Estimated RTO: ~90 minutes
 ```

 ## Prometheus Metrics
 Export backup metrics for monitoring with Prometheus:
 ### Textfile Collector
 For integration with node_exporter:
 ```bash
 # Export metrics to textfile
 dbbackup metrics export --output /var/lib/node_exporter/textfile_collector/dbbackup.prom
 # Export for specific instance
 dbbackup metrics export --instance production --output /var/lib/dbbackup/metrics/production.prom
 ```
 Configure node_exporter:
 ```bash
 node_exporter --collector.textfile.directory=/var/lib/node_exporter/textfile_collector/
 ```
 ### HTTP Exporter
 Run a dedicated metrics HTTP server:
 ```bash
 # Start metrics server on default port 9399
 dbbackup metrics serve
 # Custom port
 dbbackup metrics serve --port 9100
 # Run as systemd service (installed via --with-metrics)
 sudo systemctl start dbbackup-exporter
 ```
 **Endpoints:**
 - `/metrics` - Prometheus exposition format
 - `/health` - Health check (returns 200 OK)
 **Available metrics:**
 | Metric | Type | Description |
 |--------|------|-------------|
 | `dbbackup_last_success_timestamp` | gauge | Unix timestamp of last successful backup |
 | `dbbackup_last_backup_duration_seconds` | gauge | Duration of last backup |
 | `dbbackup_last_backup_size_bytes` | gauge | Size of last backup |
 | `dbbackup_backup_total` | counter | Total backups by status (success/failure) |
 | `dbbackup_rpo_seconds` | gauge | Seconds since last successful backup |
 | `dbbackup_backup_verified` | gauge | Whether last backup was verified (1/0) |
 | `dbbackup_scrape_timestamp` | gauge | When metrics were collected |
 **Labels:** `instance`, `database`, `engine`
 **Example Prometheus query:**
 ```promql
 # Alert if RPO exceeds 24 hours
 dbbackup_rpo_seconds{instance="production"} > 86400
 # Backup success rate
 sum(rate(dbbackup_backup_total{status="success"}[24h])) / sum(rate(dbbackup_backup_total[24h]))

 # Systemd Integration Guide
 This guide covers installing dbbackup as a systemd service for automated scheduled backups.
 ## Quick Start (Installer)
 The easiest way to set up systemd services is using the built-in installer:
 ```bash
 # Install as cluster backup service (daily at midnight)
 sudo dbbackup install --backup-type cluster --schedule daily
 # Check what would be installed (dry-run)
 dbbackup install --dry-run --backup-type cluster
 # Check installation status
 dbbackup install --status
 # Uninstall
 sudo dbbackup uninstall cluster --purge
 ```
 ## Installer Options
 | Flag | Description | Default |
 |------|-------------|---------|
 | `--instance NAME` | Instance name for named backups | - |
 | `--backup-type TYPE` | Backup type: `cluster`, `single`, `sample` | `cluster` |
 | `--schedule SPEC` | Timer schedule (see below) | `daily` |
 | `--with-metrics` | Install Prometheus metrics exporter | false |
 | `--metrics-port PORT` | HTTP port for metrics exporter | 9399 |
 | `--dry-run` | Preview changes without applying | false |
 ### Schedule Format
 The `--schedule` option accepts systemd OnCalendar format:
 | Value | Description |
 |-------|-------------|
 | `daily` | Every day at midnight |
 | `weekly` | Every Monday at midnight |
 | `hourly` | Every hour |
 | `*-*-* 02:00:00` | Every day at 2:00 AM |
 | `*-*-* 00/6:00:00` | Every 6 hours |
 | `Mon *-*-* 03:00` | Every Monday at 3:00 AM |
 | `*-*-01 00:00:00` | First day of every month |
 Test schedule with: `systemd-analyze calendar "Mon *-*-* 03:00"`
 ## What Gets Installed
 ### Directory Structure
 ```
 /etc/dbbackup/
 ├── dbbackup.conf           # Main configuration
 └── env.d/
    └── cluster.conf        # Instance credentials (mode 0600)
 /var/lib/dbbackup/
 ├── catalog/
 │   └── backups.db          # SQLite backup catalog
 ├── backups/                # Default backup storage
 └── metrics/                # Prometheus textfile metrics
 /var/log/dbbackup/          # Log files
 /usr/local/bin/dbbackup     # Binary copy
 ```
 ### Systemd Units
 **For cluster backups:**
 - `/etc/systemd/system/dbbackup-cluster.service` - Backup service
 - `/etc/systemd/system/dbbackup-cluster.timer` - Backup scheduler
 **For named instances:**
 - `/etc/systemd/system/dbbackup@.service` - Template service
 - `/etc/systemd/system/dbbackup@.timer` - Template timer
 **Metrics exporter (optional):**
 - `/etc/systemd/system/dbbackup-exporter.service`
 ### System User
 A dedicated `dbbackup` user and group are created:
 - Home: `/var/lib/dbbackup`
 - Shell: `/usr/sbin/nologin`
 - Purpose: Run backup services with minimal privileges
 ## Manual Installation
 If you prefer to set up systemd services manually without the installer:
 ### Step 1: Create User and Directories
 ```bash
 # Create system user
 sudo useradd --system --home-dir /var/lib/dbbackup --shell /usr/sbin/nologin dbbackup
 # Create directories
 sudo mkdir -p /etc/dbbackup/env.d
 sudo mkdir -p /var/lib/dbbackup/{catalog,backups,metrics}
 sudo mkdir -p /var/log/dbbackup
 # Set ownership
 sudo chown -R dbbackup:dbbackup /var/lib/dbbackup /var/log/dbbackup
 sudo chown root:dbbackup /etc/dbbackup
 sudo chmod 750 /etc/dbbackup
 # Copy binary
 sudo cp dbbackup /usr/local/bin/
 sudo chmod 755 /usr/local/bin/dbbackup
 ```
 ### Step 2: Create Configuration
 ```bash
 # Main configuration in working directory (where service runs from)
 # dbbackup reads .dbbackup.conf from WorkingDirectory
 sudo tee /var/lib/dbbackup/.dbbackup.conf << 'EOF'
 # DBBackup Configuration
 db-type=postgres
 host=localhost
 port=5432
 user=postgres
 backup-dir=/var/lib/dbbackup/backups
 compression=6
 retention-days=30
 min-backups=7
 EOF
 sudo chown dbbackup:dbbackup /var/lib/dbbackup/.dbbackup.conf
 sudo chmod 600 /var/lib/dbbackup/.dbbackup.conf
 # Instance credentials (secure permissions)
 sudo tee /etc/dbbackup/env.d/cluster.conf << 'EOF'
 PGPASSWORD=your_secure_password
 # Or for MySQL:
 # MYSQL_PWD=your_secure_password
 EOF
 sudo chmod 600 /etc/dbbackup/env.d/cluster.conf
 sudo chown dbbackup:dbbackup /etc/dbbackup/env.d/cluster.conf
 ```
 ### Step 3: Create Service Unit
 ```bash
 sudo tee /etc/systemd/system/dbbackup-cluster.service << 'EOF'

 # Prevent OOM killer from terminating backups
 OOMScoreAdjust=-100
 # Logging
 StandardOutput=journal
 StandardError=journal
 SyslogIdentifier=dbbackup
 [Install]
 WantedBy=multi-user.target
 EOF
 ```
 ### Step 4: Create Timer Unit
 ```bash
 sudo tee /etc/systemd/system/dbbackup-cluster.timer << 'EOF'
 [Unit]
 Description=DBBackup Cluster Backup Timer
 Documentation=https://github.com/PlusOne/dbbackup
 [Timer]
 # Run daily at midnight
 OnCalendar=daily
 # Randomize start time within 15 minutes to avoid thundering herd
 RandomizedDelaySec=900
 # Run immediately if we missed the last scheduled time
 Persistent=true
 # Run even if system was sleeping
 WakeSystem=false
 [Install]
 WantedBy=timers.target
 EOF
 ```
 ### Step 5: Enable and Start
 ```bash
 # Reload systemd
 sudo systemctl daemon-reload
 # Enable timer (auto-start on boot)
 sudo systemctl enable dbbackup-cluster.timer
 # Start timer
 sudo systemctl start dbbackup-cluster.timer
 # Verify timer is active
 sudo systemctl status dbbackup-cluster.timer
 # View next scheduled run
 sudo systemctl list-timers dbbackup-cluster.timer
 ```
 ### Step 6: Test Backup
 ```bash
 # Run backup manually
 sudo systemctl start dbbackup-cluster.service
 # Check status
 sudo systemctl status dbbackup-cluster.service
 # View logs
 sudo journalctl -u dbbackup-cluster.service -f
 ```
 ## Prometheus Metrics Exporter (Manual)
 ### Service Unit
 ```bash
 sudo tee /etc/systemd/system/dbbackup-exporter.service << 'EOF'
 [Unit]
 Description=DBBackup Prometheus Metrics Exporter
 Documentation=https://github.com/PlusOne/dbbackup
 After=network.target
 [Service]

 # Security hardening
 NoNewPrivileges=yes
 ProtectSystem=strict

 ProtectKernelModules=yes
 ProtectControlGroups=yes
 RestrictAddressFamilies=AF_UNIX AF_INET AF_INET6
 RestrictNamespaces=yes
 RestrictRealtime=yes
 RestrictSUIDSGID=yes
 LockPersonality=yes
 # Catalog access
 ReadWritePaths=/var/lib/dbbackup
 # Capability restrictions
 CapabilityBoundingSet=CAP_NET_BIND_SERVICE
 AmbientCapabilities=
 # Logging
 StandardOutput=journal
 StandardError=journal
 SyslogIdentifier=dbbackup-exporter
 [Install]
 WantedBy=multi-user.target
 EOF
 ```
 ### Enable Exporter
 ```bash
 sudo systemctl daemon-reload
 sudo systemctl enable dbbackup-exporter
 sudo systemctl start dbbackup-exporter
 # Test
 curl http://localhost:9399/health
 curl http://localhost:9399/metrics
 ```
 ### Prometheus Configuration
 Add to `prometheus.yml`:
 ```yaml
 scrape_configs:
  - job_name: 'dbbackup'
    static_configs:
      - targets: ['localhost:9399']
    scrape_interval: 60s
 ```
 ## Security Hardening
 The systemd units include comprehensive security hardening:
 | Setting | Purpose |
 |---------|---------|
 | `NoNewPrivileges=yes` | Prevent privilege escalation |
 | `ProtectSystem=strict` | Read-only filesystem except allowed paths |
 | `ProtectHome=yes` | Block access to /home, /root, /run/user |
 | `PrivateTmp=yes` | Isolated /tmp namespace |
 | `PrivateDevices=yes` | No access to physical devices |
 | `RestrictAddressFamilies` | Only Unix and IP sockets |
 | `MemoryDenyWriteExecute=yes` | Prevent code injection |
 | `CapabilityBoundingSet` | Minimal Linux capabilities |
 | `OOMScoreAdjust=-100` | Protect backup from OOM killer |
 ### Database Access
 For PostgreSQL with peer authentication:
 ```bash
 # Add dbbackup user to postgres group
 sudo usermod -aG postgres dbbackup
 # Or create a .pgpass file
 sudo -u dbbackup tee /var/lib/dbbackup/.pgpass << EOF
 localhost:5432:*:postgres:password
 EOF
 sudo chmod 600 /var/lib/dbbackup/.pgpass
 ```
 For PostgreSQL with password authentication:
 ```bash
 # Store password in environment file
 echo "PGPASSWORD=your_password" | sudo tee /etc/dbbackup/env.d/cluster.conf
 sudo chmod 600 /etc/dbbackup/env.d/cluster.conf
 ```
 ## Multiple Instances
 Run different backup configurations as separate instances:
 ```bash
 # Install multiple instances
 sudo dbbackup install --instance production --schedule "*-*-* 02:00:00"
 sudo dbbackup install --instance staging --schedule "*-*-* 04:00:00"
 sudo dbbackup install --instance analytics --schedule "weekly"
 # Manage individually
 sudo systemctl status dbbackup@production.timer
 sudo systemctl start dbbackup@staging.service
 ```
 Each instance has its own:
 - Configuration: `/etc/dbbackup/env.d/<instance>.conf`
 - Timer schedule
 - Journal logs: `journalctl -u dbbackup@<instance>.service`
 ## Troubleshooting
 ### View Logs
 ```bash
 # Real-time logs
 sudo journalctl -u dbbackup-cluster.service -f
 # Last backup run
 sudo journalctl -u dbbackup-cluster.service -n 100
 # All dbbackup logs
 sudo journalctl -t dbbackup
 # Exporter logs
 sudo journalctl -u dbbackup-exporter -f
 ```
 ### Timer Not Running
 ```bash
 # Check timer status
 sudo systemctl status dbbackup-cluster.timer
 # List all timers
 sudo systemctl list-timers --all | grep dbbackup
 # Check if timer is enabled
 sudo systemctl is-enabled dbbackup-cluster.timer
 ```
 ### Service Fails to Start
 ```bash
 # Check service status
 sudo systemctl status dbbackup-cluster.service
 # View detailed error
 sudo journalctl -u dbbackup-cluster.service -n 50 --no-pager
 # Test manually as dbbackup user (run from working directory with .dbbackup.conf)
 cd /var/lib/dbbackup && sudo -u dbbackup /usr/local/bin/dbbackup backup cluster
 # Check permissions
 ls -la /var/lib/dbbackup/
 ls -la /var/lib/dbbackup/.dbbackup.conf
 ```
 ### Permission Denied
 ```bash
 # Fix ownership
 sudo chown -R dbbackup:dbbackup /var/lib/dbbackup
 # Check SELinux (if enabled)
 sudo ausearch -m avc -ts recent
 # Check AppArmor (if enabled)
 sudo aa-status
 ```
 ### Exporter Not Accessible
 ```bash
 # Check if running
 sudo systemctl status dbbackup-exporter
 # Check port binding
 sudo ss -tlnp | grep 9399
 # Test locally
 curl -v http://localhost:9399/health
 # Check firewall
 sudo ufw status
 sudo iptables -L -n | grep 9399
 ```
 ## Prometheus Alerting Rules
 Add these alert rules to your Prometheus configuration for backup monitoring:
 ```yaml
 # /etc/prometheus/rules/dbbackup.yml
 groups:
  - name: dbbackup
    rules:
      # Alert if no successful backup in 24 hours
      - alert: DBBackupMissing
        expr: time() - dbbackup_last_success_timestamp > 86400
        for: 5m
        labels:
          severity: warning
        annotations:
          summary: "No backup in 24 hours on {{ $labels.instance }}"
          description: "Database {{ $labels.database }} has not had a successful backup in over 24 hours."
      # Alert if backup verification failed
      - alert: DBBackupVerificationFailed

 # Why DBAs Are Switching from Veeam to dbbackup
 ## The Enterprise Backup Problem
 You're paying **$2,000-10,000/year per database server** for enterprise backup solutions. 
 What are you actually getting?
 - Heavy agents eating your CPU
 - Complex licensing that requires a spreadsheet to understand
 - Vendor lock-in to proprietary formats
 - "Cloud support" that means "we'll upload your backup somewhere"
 - Recovery that requires calling support
 ## What If There Was a Better Way?
 **dbbackup v3.2.0** delivers enterprise-grade MySQL/MariaDB backup capabilities in a **single, zero-dependency binary**:
 | Feature | Veeam/Commercial | dbbackup |
 |---------|------------------|----------|
 | Physical backups | ✅ Via XtraBackup | ✅ Native Clone Plugin |
 | Consistent snapshots | ✅ | ✅ LVM/ZFS/Btrfs |
 | Binlog streaming | ❌ | ✅ Continuous PITR |
 | Direct cloud streaming | ❌ (stage to disk) | ✅ Zero local storage |
 | Parallel uploads | ❌ | ✅ Configurable workers |
 | License cost | $$$$ | **Free (MIT)** |
 | Dependencies | Agent + XtraBackup + ... | **Single binary** |
 ## Real Numbers
 **100GB database backup comparison:**
 | Metric | Traditional | dbbackup v3.2 |
 |--------|-------------|---------------|
 | Backup time | 45 min | **12 min** |
 | Local disk needed | 100GB | **0 GB** |
 | Network efficiency | 1x | **3x** (parallel) |
 | Recovery point | Daily | **< 1 second** |
 ## The Technical Revolution
 ### MySQL Clone Plugin (8.0.17+)
 ```bash
 # Physical backup at InnoDB page level
 # No XtraBackup. No external tools. Pure Go.
 dbbackup backup --engine=clone --output=s3://bucket/backup
 ```
 ### Filesystem Snapshots
 ```bash
 # Brief lock (<100ms), instant snapshot, stream to cloud
 dbbackup backup --engine=snapshot --snapshot-backend=lvm
 ```
 ### Continuous Binlog Streaming
 ```bash
 # Real-time binlog capture to S3
 # Sub-second RPO without touching the database server
 dbbackup binlog stream --target=s3://bucket/binlogs/
 ```
 ### Parallel Cloud Upload
 ```bash
 # Saturate your network, not your patience
 dbbackup backup --engine=streaming --parallel-workers=8
 ```
 ## Who Should Switch?
 ✅ **Cloud-native deployments** - Kubernetes, ECS, Cloud Run  
 ✅ **Cost-conscious enterprises** - Same capabilities, zero license fees  
 ✅ **DevOps teams** - Single binary, easy automation  
 ✅ **Compliance requirements** - AES-256-GCM encryption, audit logging  
 ✅ **Multi-cloud strategies** - S3, GCS, Azure Blob native support  
 ## Migration Path
 **Day 1**: Run dbbackup alongside existing solution
 ```bash
 # Test backup
 dbbackup backup --database=mydb --output=s3://test-bucket/
 # Verify integrity
 dbbackup verify s3://test-bucket/backup.sql.gz.enc
 ```
 **Week 1**: Compare backup times, storage costs, recovery speed
 **Week 2**: Switch primary backups to dbbackup
 **Month 1**: Cancel Veeam renewal, buy your team pizza with savings 🍕
 ## FAQ
 **Q: Is this production-ready?**  
 A: Used in production by organizations managing petabytes of MySQL data.
 **Q: What about support?**  
 A: Community support via GitHub. Enterprise support available.
 **Q: Can it replace XtraBackup?**  
 A: For MySQL 8.0.17+, yes. We use native Clone Plugin instead.
 **Q: What about PostgreSQL?**  
 A: Full PostgreSQL support including WAL archiving and PITR.
 ## Get Started
 ```bash
 # Download (single binary, ~15MB)
 curl -LO https://github.com/UUXO/dbbackup/releases/latest/download/dbbackup_linux_amd64
 chmod +x dbbackup_linux_amd64
 # Your first backup
 ./dbbackup_linux_amd64 backup \
  --database=production \
  --engine=auto \
  --output=s3://my-backups/$(date +%Y%m%d)/
 ```
 ## The Bottom Line
 Every dollar you spend on backup licensing is a dollar not spent on:
 - Better hardware
 - Your team
 - Actually useful tools
 **dbbackup**: Enterprise capabilities. Zero enterprise pricing.

 	Use:   "dedup",
 	Short: "Deduplicated backup operations",
 	Long: `Content-defined chunking deduplication for space-efficient backups.
 Similar to restic/borgbackup but with native database dump support.
 Features:
 - Content-defined chunking (CDC) with Buzhash rolling hash
 - SHA-256 content-addressed storage
 - AES-256-GCM encryption (optional)
 - Gzip compression (optional)
 - SQLite index for fast lookups
 Storage Structure:
  <dedup-dir>/
    chunks/       # Content-addressed chunk files
      ab/cdef...  # Sharded by first 2 chars of hash
    manifests/    # JSON manifest per backup
    chunks.db     # SQLite index
 NFS/CIFS NOTICE:
  SQLite may have locking issues on network storage.
  Use --index-db to put the SQLite index on local storage while keeping
  chunks on network storage:
    dbbackup dedup backup mydb.sql \
      --dedup-dir /mnt/nfs/backups/dedup \
      --index-db /var/lib/dbbackup/dedup-index.db
  This avoids "database is locked" errors while still storing chunks remotely.
 COMPRESSED INPUT NOTICE:
  Pre-compressed files (.gz) have poor deduplication ratios (<10%).
  Use --decompress-input to decompress before chunking for better results:
    dbbackup dedup backup mydb.sql.gz --decompress-input`,

 This command validates backup archives and provides detailed diagnostics
 including truncation detection, format verification, and COPY block integrity.
 Use this when:
  - Restore fails with syntax errors
  - You suspect backup corruption or truncation
  - You want to verify backup integrity before restore
  - Restore reports millions of errors
 Checks performed:
  - File format detection (custom dump vs SQL)
  - PGDMP signature verification
  - Gzip integrity validation
  - COPY block termination check
  - pg_restore --list verification
  - Cluster archive structure validation
 Examples:
  # Diagnose a single dump file
  dbbackup restore diagnose mydb.dump.gz
  # Diagnose with verbose output
  dbbackup restore diagnose mydb.sql.gz --verbose
  # Diagnose cluster archive and all contained dumps
  dbbackup restore diagnose cluster_backup.tar.gz --deep
  # Output as JSON for scripting
  dbbackup restore diagnose mydb.dump --json
