fix: streaming tar verification for large cluster archives (100GB+)

- Increase timeout from 60 to 180 minutes for very large archives
- Use streaming pipes instead of buffering entire tar listing
- Only mark as corrupted for clear corruption signals (unexpected EOF, invalid gzip)
- Prevents false CORRUPTED errors on valid large archives

-# Emoticon Removal Plan for Python Code
-
-## ⚠️ CRITICAL: Code Must Remain Functional After Removal
-
-This document outlines a **safe, systematic approach** to removing emoticons from Python code without breaking functionality.
-
----
-
-## 1. Identification Phase
-
-### 1.1 Where Emoticons CAN Safely Exist (Safe to Remove)
-| Location | Risk Level | Action |
-|----------|------------|--------|
-| Comments (`# 🎉 Success!`) | ✅ SAFE | Remove or replace with text |
-| Docstrings (`"""📌 Note:..."""`) | ✅ SAFE | Remove or replace with text |
-| Print statements for decoration (`print("✅ Done!")`) | ⚠️ LOW | Replace with ASCII or text |
-| Logging messages (`logger.info("🔥 Starting...")`) | ⚠️ LOW | Replace with text equivalent |
-
-### 1.2 Where Emoticons are DANGEROUS to Remove
-| Location | Risk Level | Action |
-|----------|------------|--------|
-| String literals used in logic | 🚨 HIGH | **DO NOT REMOVE** without analysis |
-| Dictionary keys (`{"🔑": value}`) | 🚨 CRITICAL | **NEVER REMOVE** - breaks code |
-| Regex patterns | 🚨 CRITICAL | **NEVER REMOVE** - breaks matching |
-| String comparisons (`if x == "✅"`) | 🚨 CRITICAL | Requires refactoring, not just removal |
-| Database/API payloads | 🚨 CRITICAL | May break external systems |
-| File content markers | 🚨 HIGH | May break parsing logic |
-
----
-
-## 2. Pre-Removal Checklist
-
-### 2.1 Before ANY Changes
-- [ ] **Full backup** of the codebase
-- [ ] **Run all tests** and record baseline results
-- [ ] **Document all emoticon locations** with grep/search
-- [ ] **Identify emoticon usage patterns** (decorative vs. functional)
-
-### 2.2 Discovery Commands
-```bash
-# Find all files with emoticons (Unicode range for common emojis)
-grep -rn --include="*.py" -P '[\x{1F300}-\x{1F9FF}]' .
-
-# Find emoticons in strings
-grep -rn --include="*.py" -E '["'"'"'][^"'"'"']*[\x{1F300}-\x{1F9FF}]' .
-
-# List unique emoticons used
-grep -oP '[\x{1F300}-\x{1F9FF}]' *.py | sort -u
-```
-
----
-
-## 3. Replacement Strategy
-
-### 3.1 Semantic Replacement Table
-| Emoticon | Text Replacement | Context |
-|----------|------------------|---------|
-| ✅ | `[OK]` or `[SUCCESS]` | Status indicators |
-| ❌ | `[FAIL]` or `[ERROR]` | Error indicators |
-| ⚠️ | `[WARNING]` | Warning messages |
-| 🔥 | `[HOT]` or `` (remove) | Decorative |
-| 🎉 | `[DONE]` or `` (remove) | Celebration/completion |
-| 📌 | `[NOTE]` | Notes/pinned items |
-| 🚀 | `[START]` or `` (remove) | Launch/start indicators |
-| 💾 | `[SAVE]` | Save operations |
-| 🔑 | `[KEY]` | Key/authentication |
-| 📁 | `[FILE]` | File operations |
-| 🔍 | `[SEARCH]` | Search operations |
-| ⏳ | `[WAIT]` or `[LOADING]` | Progress indicators |
-| 🛑 | `[STOP]` | Stop/halt indicators |
-| ℹ️ | `[INFO]` | Information |
-| 🐛 | `[BUG]` or `[DEBUG]` | Debug messages |
-
-### 3.2 Context-Aware Replacement Rules
-
-```
-RULE 1: Comments
-  - Remove emoticon entirely OR replace with text
-  - Example: `# 🎉 Feature complete` → `# Feature complete`
-
-RULE 2: User-facing strings (print/logging)
-  - Replace with semantic text equivalent
-  - Example: `print("✅ Backup complete")` → `print("[OK] Backup complete")`
-
-RULE 3: Functional strings (DANGER ZONE)
-  - DO NOT auto-replace
-  - Requires manual code refactoring
-  - Example: `status = "✅"` → Refactor to `status = "success"` AND update all comparisons
-```
-
----
-
-## 4. Safe Removal Process
-
-### Step 1: Audit
-```python
-# Python script to audit emoticon usage
-import re
-import ast
-
-EMOJI_PATTERN = re.compile(
-    "["
-    "\U0001F300-\U0001F9FF"  # Symbols & Pictographs
-    "\U00002600-\U000026FF"  # Misc symbols
-    "\U00002700-\U000027BF"  # Dingbats
-    "\U0001F600-\U0001F64F"  # Emoticons
-    "]+"
-)
-
-def audit_file(filepath):
-    with open(filepath, 'r', encoding='utf-8') as f:
-        content = f.read()
-    
-    # Parse AST to understand context
-    tree = ast.parse(content)
-    
-    findings = []
-    for lineno, line in enumerate(content.split('\n'), 1):
-        matches = EMOJI_PATTERN.findall(line)
-        if matches:
-            # Determine context (comment, string, etc.)
-            context = classify_context(line, matches)
-            findings.append({
-                'line': lineno,
-                'content': line.strip(),
-                'emojis': matches,
-                'context': context,
-                'risk': assess_risk(context)
-            })
-    return findings
-
-def classify_context(line, matches):
-    stripped = line.strip()
-    if stripped.startswith('#'):
-        return 'COMMENT'
-    if 'print(' in line or 'logging.' in line or 'logger.' in line:
-        return 'OUTPUT'
-    if '==' in line or '!=' in line:
-        return 'COMPARISON'
-    if re.search(r'["\'][^"\']*$', line.split('#')[0]):
-        return 'STRING_LITERAL'
-    return 'UNKNOWN'
-
-def assess_risk(context):
-    risk_map = {
-        'COMMENT': 'LOW',
-        'OUTPUT': 'LOW',
-        'COMPARISON': 'CRITICAL',
-        'STRING_LITERAL': 'HIGH',
-        'UNKNOWN': 'HIGH'
-    }
-    return risk_map.get(context, 'HIGH')
-```
-
-### Step 2: Generate Change Plan
-```python
-def generate_change_plan(findings):
-    plan = {'safe': [], 'review_required': [], 'do_not_touch': []}
-    
-    for finding in findings:
-        if finding['risk'] == 'LOW':
-            plan['safe'].append(finding)
-        elif finding['risk'] == 'HIGH':
-            plan['review_required'].append(finding)
-        else:  # CRITICAL
-            plan['do_not_touch'].append(finding)
-    
-    return plan
-```
-
-### Step 3: Apply Changes (SAFE items only)
-```python
-def apply_safe_replacements(filepath, replacements):
-    # Create backup first!
-    import shutil
-    shutil.copy(filepath, filepath + '.backup')
-    
-    with open(filepath, 'r', encoding='utf-8') as f:
-        content = f.read()
-    
-    for old, new in replacements:
-        content = content.replace(old, new)
-    
-    with open(filepath, 'w', encoding='utf-8') as f:
-        f.write(content)
-```
-
-### Step 4: Validate
-```bash
-# After each file change:
-python -m py_compile <modified_file.py>  # Syntax check
-pytest <related_tests>                     # Run tests
-```
-
----
-
-## 5. Validation Checklist
-
-### After EACH File Modification
-- [ ] File compiles without syntax errors (`python -m py_compile file.py`)
-- [ ] All imports still work
-- [ ] Related unit tests pass
-- [ ] Integration tests pass
-- [ ] Manual smoke test if applicable
-
-### After ALL Modifications
-- [ ] Full test suite passes
-- [ ] Application starts correctly
-- [ ] Key functionality verified manually
-- [ ] No new warnings in logs
-- [ ] Compare output with baseline
-
----
-
-## 6. Rollback Plan
-
-### If Something Breaks
-1. **Immediate**: Restore from `.backup` files
-2. **Git**: `git checkout -- <file>` or `git stash pop`
-3. **Full rollback**: Restore from pre-change backup
-
-### Keep Until Verified
-```bash
-# Backup storage structure
-backups/
-├── pre_emoticon_removal/
-│   ├── timestamp.tar.gz
-│   └── git_commit_hash.txt
-└── individual_files/
-    ├── file1.py.backup
-    └── file2.py.backup
-```
-
----
-
-## 7. Implementation Order
-
-1. **Phase 1**: Comments only (LOWEST risk)
-2. **Phase 2**: Docstrings (LOW risk)
-3. **Phase 3**: Print/logging statements (LOW-MEDIUM risk)
-4. **Phase 4**: Manual review items (HIGH risk) - one by one
-5. **Phase 5**: NEVER touch CRITICAL items without full refactoring
-
----
-
-## 8. Example Workflow
-
-```bash
-# 1. Create full backup
-git stash && git checkout -b emoticon-removal
-
-# 2. Run audit script
-python emoticon_audit.py > audit_report.json
-
-# 3. Review audit report
-cat audit_report.json | jq '.do_not_touch'  # Check critical items
-
-# 4. Apply safe changes only
-python apply_safe_changes.py --dry-run  # Preview first!
-python apply_safe_changes.py            # Apply
-
-# 5. Validate after each change
-python -m pytest tests/
-
-# 6. Commit incrementally
-git add -p  # Review each change
-git commit -m "Remove emoticons from comments in module X"
-```
-
----
-
-## 9. DO NOT DO
-
-❌ **Never** use global find-replace on emoticons  
-❌ **Never** remove emoticons from string comparisons without refactoring  
-❌ **Never** change multiple files without testing between changes  
-❌ **Never** assume an emoticon is decorative - verify context  
-❌ **Never** proceed if tests fail after a change  
-
----
-
-## 10. Sign-Off Requirements
-
-Before merging emoticon removal changes:
-- [ ] All tests pass (100%)
-- [ ] Code review by second developer
-- [ ] Manual testing of affected features
-- [ ] Documented all CRITICAL items left unchanged (with justification)
-- [ ] Backup verified and accessible

+# 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
+```

-# 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** |
