-## [3.42.0] - 2026-01-07 "The Operator"
+## [3.42.34] - 2026-01-14 "Filesystem Abstraction"

-### Added - 🐧 Systemd Integration & Prometheus Metrics
+### 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

+# 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.

+## 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 \

+### 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
+```
+

-### Features
+### Deduplication - Resistance is Futile
+
+Content-defined chunking deduplication for space-efficient backups. Like restic/borgbackup but with **native database dump support**.
+
+```bash
+# First backup: 5MB stored
+dbbackup dedup backup mydb.dump
+
+# Second backup (modified): only 1.6KB new data stored!
+# 100% deduplication ratio
+dbbackup dedup backup mydb_modified.dump
+```
+
+#### Features
+- **Gear Hash CDC** - Content-defined chunking with 92%+ overlap on shifted data
+- **SHA-256 Content-Addressed** - Chunks stored by hash, automatic deduplication
+- **AES-256-GCM Encryption** - Optional per-chunk encryption
+- **Gzip Compression** - Optional compression (enabled by default)
+- **SQLite Index** - Fast chunk lookups and statistics
+
+#### Commands
+```bash
+dbbackup dedup backup <file>              # Create deduplicated backup
+dbbackup dedup backup <file> --encrypt    # With AES-256-GCM 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
+dbbackup dedup gc                         # Garbage collect unreferenced chunks
+```
+
+#### Storage Structure
+```
+<backup-dir>/dedup/
+  chunks/           # Content-addressed chunk files
+    ab/cdef1234...  # Sharded by first 2 chars of hash
+  manifests/        # JSON manifest per backup
+  chunks.db         # SQLite index

-# 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 single mydb --db-type mysql --cloud s3://bucket/backups/
-```
-
-### 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 single mydb --cloud s3://test-bucket/
-
-# Verify integrity
-dbbackup verify s3://test-bucket/mydb_20260115.dump.gz
-```
-
-**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 single production \
-  --db-type mysql \
-  --cloud s3://my-backups/
-```
-
-## 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.

+- 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
+

+    manifests/    # JSON manifest per backup
