# Plex Backup System Transition Summary
**Date:** June 21, 2025
**Author:** Peter Wood <peter@peterwood.dev>
## 🔄 Transition Overview
The Plex backup system has been transitioned from custom scripts to Plex's built-in scheduled backup functionality to reduce complexity and improve reliability.
## ✅ Changes Made
### 1. **Disabled Custom Backup Cron Jobs**
- ✅ Removed daily Plex backup job (4:15 AM)
- ✅ Removed daily integrity check job (6:00 AM)
- ✅ Removed daily backup validation job (7:00 AM)
- ✅ Removed weekly backup report job (Sunday 8:00 AM)
### 2. **Plex Built-in Backup System Active**
-**Frequency:** Every 3 days (automatic)
-**Location:** Database directory + NAS mount `/mnt/share/media/backups/plex`
-**Pattern:** `*.backup.YYYYMMDD_HHMMSS`
-**Current Status:** Active with 1 backup file found
### 3. **Updated Documentation**
- ✅ Updated README.md to reflect backup system changes
- ✅ Marked custom backup scripts as disabled/limited use
- ✅ Added new utility script: `check-plex-builtin-backups.sh`
- ✅ Updated Quick Start and Best Practices sections
### 4. **Scripts Status Change**
| Script | Previous Status | New Status |
|--------|----------------|------------|
| `backup-plex.sh` | Active (daily cron) | ❌ **DISABLED** (emergency manual use only) |
| `validate-plex-backups.sh` | Active (daily cron) | ⚠️ **LIMITED USE** (legacy backups only) |
| `monitor-plex-backup.sh` | Active monitoring | ⚠️ **LIMITED USE** (basic system monitoring) |
| `plex-db-manager.sh` | Active | ✅ **ACTIVE** (manual health checks) |
| `nuclear-plex-recovery.sh` | Emergency use | ✅ **ACTIVE** (emergency recovery) |
| `plex.sh` | Service management | ✅ **ACTIVE** (service management) |
| `check-plex-builtin-backups.sh` | N/A | ⭐ **NEW** (monitor built-in backups) |
## 🎯 Current Recommended Workflow
### Daily Operations (Automated)
- **Plex Built-in Backups:** Run automatically every 3 days
- **No manual intervention required**
### Weekly Operations (Manual)
```bash
# Health check
./plex-db-manager.sh check
# Check backup status
./check-plex-builtin-backups.sh
# Service status
./plex.sh status
```
### Emergency Procedures (Unchanged)
```bash
# Database issues
./plex-db-manager.sh check
./plex.sh restart
sudo ./nuclear-plex-recovery.sh --dry-run
sudo ./nuclear-plex-recovery.sh --auto
# Validation after recovery
./validate-plex-recovery.sh
```
## 📊 Benefits of This Change
### ✅ **Advantages**
1. **Reduced Complexity:** Fewer moving parts and scripts to maintain
2. **Native Integration:** Plex handles its own backup timing and lifecycle
3. **Elimination of Conflicts:** No risk of custom scripts interfering with Plex
4. **Simplified Monitoring:** One tool (`check-plex-builtin-backups.sh`) for status
5. **Lower Maintenance:** No custom cron schedules to manage
### ⚠️ **Considerations**
1. **Less Control:** Cannot customize backup frequency (fixed at 3 days)
2. **Limited Validation:** Cannot validate Plex backups with external tools
3. **Dependency:** Reliant on Plex's backup implementation working correctly
## 🔍 Monitoring Built-in Backups
### New Utility Script
```bash
./check-plex-builtin-backups.sh # Basic status
./check-plex-builtin-backups.sh --detailed # Detailed information
```
### Manual Commands
```bash
# Check latest backup
ls -lath "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/"*.backup.* | head -1
# List all backups
find "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases" -name "*.backup.*" -exec ls -lah {} \;
# Check backup age
stat "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/"*.backup.* | grep Modify
```
## 📁 File System Changes
### Cron Configuration
- **File:** `/home/acedanger/shell/crontab/crontab-europa.txt`
- **Status:** Plex backup entries commented out/disabled
- **Applied:** Yes (via `manage-enhanced-crontab.sh install`)
### Custom Backup Files
- **Location:** `/mnt/share/media/backups/plex/plex-backup-*.tar.gz`
- **Status:** Legacy files preserved for historical reference
- **Count:** 5 files found (from previous custom backup system)
### Built-in Backup Files
- **Location:** `/var/lib/plexmediaserver/.../Databases/*.backup.*`
- **Current:** 1 active backup file found
- **Latest:** `com.plexapp.plugins.library.db.backup.20250621_063833` (149M)
## 🚨 Emergency Access
### If Built-in Backups Fail
Custom backup scripts remain available for emergency use:
```bash
# Emergency backup creation
./backup-plex.sh --non-interactive --disable-auto-repair
# Emergency validation
./validate-plex-backups.sh --latest
```
### Recovery Procedures
- **Nuclear recovery:** `nuclear-plex-recovery.sh` unchanged
- **Service management:** `plex.sh` unchanged
- **Health checks:** `plex-db-manager.sh` unchanged
## 📋 Testing Results
### Backup Status Check (June 21, 2025)
```
✅ Plex database directory found
✅ Found 1 built-in backup file(s)
📅 Latest backup: 2025-06-21 06:38:56 (149M)
✅ NAS backup directory accessible
📦 Found 5 legacy custom backup files
✅ Custom backup system: DISABLED
✅ Plex built-in backups: ACTIVE
```
### Cron Verification
```bash
$ sudo crontab -l | grep -E "(plex|backup)"
# Returns: No active Plex backup cron jobs (successfully disabled)
```
## 📞 Rollback Plan
If Plex built-in backups prove unreliable, the custom system can be re-enabled:
1. **Uncomment cron entries** in `/home/acedanger/shell/crontab/crontab-europa.txt`
2. **Re-apply crontab:** `./manage-enhanced-crontab.sh install`
3. **Update README.md** to reflect re-enabled status
4. **Monitor both systems** until transition is complete
## 🏁 Conclusion
The transition to Plex built-in backups simplifies the backup architecture while maintaining all emergency recovery capabilities. The system is now more aligned with Plex's native functionality and reduces the risk of script conflicts that contributed to previous database corruption issues.
**Status:****TRANSITION COMPLETE**
**Next Review:** July 21, 2025 (1 month follow-up)

# Plex Database Corruption Resolution Summary
## ✅ ISSUE RESOLVED: Auto-Repair Cycle Causing Corruption
### Root Cause Identified
The primary cause of your Plex database corruption was an **aggressive auto-repair schedule** running every 30 minutes via cron:
```bash
# PROBLEMATIC (FIXED):
*/30 * * * * /home/acedanger/shell/plex/backup-plex.sh --check-integrity --auto-repair
```
This caused:
- 48+ service stops/starts per day
- WAL file manipulation conflicts
- Repair cascading failures
- Race conditions during service transitions
### ✅ Changes Applied
#### 1. **Fixed Crontab Schedule**
- **Before**: Auto-repair every 30 minutes + daily backup with auto-repair
- **After**:
- Daily read-only integrity check (6 AM)
- Daily backup with auto-repair **disabled** (4:15 AM)
- Manual repair intervention required
#### 2. **Disabled Auto-Repair Default**
- Changed `backup-plex.sh` default from `AUTO_REPAIR=true` to `AUTO_REPAIR=false`
- Prevents automatic repair loops that were causing corruption
#### 3. **Created Consolidated Management Tool**
- New script: `plex-db-manager.sh`
- Safe, read-only integrity checking
- Manual repair intervention (currently disabled for safety)
- Proper service management with synchronization
#### 4. **Database Status** ✅
Current check shows: **ALL DATABASES HEALTHY**
- Main database: integrity check PASSED
- Blobs database: integrity check PASSED
## 📋 Script Redundancy Analysis
### Scripts with Overlapping Functionality
1. **`plex.sh`** - Service management + basic repair
2. **`backup-plex.sh`** - Backup + auto-repair logic
3. **`plex-database-repair.sh`** - Dedicated repair functions
4. **`recover-plex-database.sh`** - Advanced recovery methods
5. **`nuclear-plex-recovery.sh`** - Nuclear recovery
6. **`restore-plex.sh`** - Backup restoration
### Consolidation Recommendations
#### Keep Active:
- **`backup-plex.sh`** - Primary backup (with auto-repair disabled)
- **`plex-db-manager.sh`** - New consolidated management tool
- **`plex.sh`** - Basic service management
- **`nuclear-plex-recovery.sh`** - Last resort recovery
#### Consider Deprecating:
- **`plex-database-repair.sh`** - Functionality moved to `plex-db-manager.sh`
- **`recover-plex-database.sh`** - Similar functionality in other scripts
- **`restore-plex.sh`** - Basic functionality covered elsewhere
## 🛡️ Prevention Measures Implemented
### 1. **Conservative Backup Schedule**
```bash
# Read-only check (daily at 6 AM)
0 6 * * * backup-plex.sh --check-integrity --disable-auto-repair
# Backup without auto-repair (daily at 4:15 AM)
15 4 * * * backup-plex.sh --non-interactive --disable-auto-repair
```
### 2. **Manual Intervention Required**
- No automatic repairs unless explicitly requested
- All repair operations require manual approval
- Comprehensive logging for audit trail
### 3. **Safe Service Management**
- Proper service stop/start synchronization
- Extended timeouts for clean shutdowns
- Race condition prevention
## 📊 Expected Improvements
1. **Stability**: Eliminated 47 daily service interruptions
2. **Reliability**: No more auto-repair corruption loops
3. **Performance**: Reduced I/O load on database files
4. **Maintainability**: Centralized database management
## 🔧 Usage Going Forward
### Regular Monitoring:
```bash
# Check database health (safe, read-only)
./plex-db-manager.sh check
```
### If Issues Detected:
```bash
# View detailed logs
tail -f /home/acedanger/shell/plex/logs/plex-backup-$(date +%Y-%m-%d).log
# Manual repair (when re-enabled)
./plex-db-manager.sh repair
```
### Emergency Recovery:
```bash
# Only if all else fails
sudo ./nuclear-plex-recovery.sh --auto
```
## ⚠️ Critical Notes
1. **Auto-repair is temporarily disabled** until stability is confirmed
2. **Manual intervention required** for any database issues
3. **Monitor logs closely** for the next week to ensure stability
4. **Backup integrity** should improve significantly

**Date Fixed**: June 21, 2025
**Issue**: 30-minute auto-repair cycle causing database corruption
**Resolution**: Disabled aggressive auto-repair, implemented safe backup schedule
**Status**: ✅ RESOLVED - Databases currently healthy

### 🔍 Validation & Monitoring
**Author:** Peter Wood <peter@peterwood.dev> #### `validate-plex-backups.sh` ⚠️ **LIMITED USE**
**Backup validation - Now limited to legacy backup validation**
**Status:** ⚠️ **LIMITED USE** (June 21, 2025)
**Reason:** Mainly applies to old custom backup files, not Plex built-in backups
**Current Functionality:**
- Can validate legacy custom backup archives
- Database integrity checking within old backups
- Historical backup analysis for troubleshooting
**Limited Usage:**
```bash
./validate-plex-backups.sh --latest # Validate latest custom backup (if any)
./validate-plex-backups.sh --help # Show available options
```
**For Plex Built-in Backups:**
```bash
# Plex built-in backups don't need external validation
# They're automatically managed and verified by Plex
ls -la "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/"*.backup.*
```
#### `monitor-plex-backup.sh` ⚠️ **LIMITED USE**

**Reason:** Custom backup monitoring less relevant with Plex built-in system
**Available Functionality:**
- General system health monitoring
- Service status verification
- Disk space monitoring
**Usage:**
```bash
./monitor-plex-backup.sh --summary # Basic system summary
./monitor-plex-backup.sh --help # Show available options
```
**Alternative: Check Plex Built-in Backup Status**
```bash
# Check when last backup was created
stat "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/"*.backup.* 2>/dev/null | grep Modify | tail -1
# Check backup file sizes
ls -lah "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/"*.backup.* 2>/dev/null
```

## 🔧 Configuration **With Plex Built-in Backups (Current System):**
### Environment Setup 1. **Automated Operations:**
- **Plex Built-in Backups:** Every 3 days (automatic, no user intervention)
- **Service Monitoring:** `plex.sh status` for operational checks (manual)
All scripts share common configuration patterns: 2. **Manual Health Monitoring (as needed):**
- **Database Health:** `plex-db-manager.sh check` for manual assessment
- **Service Status:** `plex.sh status` for service verification
3. **Emergency Recovery Workflow (unchanged):**
- **Issue Detection:** Service failures or manual observation
- **Initial Assessment:** `plex-db-manager.sh check` to diagnose problems
- **Service Recovery:** `plex.sh restart` for service-level issues
- **Nuclear Recovery:** `nuclear-plex-recovery.sh --auto` for database corruption
- **Post-Recovery Verification:** `validate-plex-recovery.sh` confirms recovery
**Built-in Backup Management:**
```bash
# Check latest Plex built-in backup
ls -lath "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/"*.backup.* | head -1
# Monitor backup frequency (should be every 3 days)
ls -la "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/"*.backup.*

- ✅ Created consolidated database manager (`plex-db-manager.sh`)
- ✅ Enhanced service management with safer shutdown procedures
- **Author:** Peter Wood ## 💡 Best Practices
- **Email:** <peter@peterwood.dev>
### Current Recommended Workflow (Updated)
1. **Let Plex Handle Backups:**
- ✅ Plex built-in backups run automatically every 3 days
- ✅ No manual intervention needed for routine backups
- ✅ Backups are stored in NAS location: `/mnt/share/media/backups/plex`
2. **Manual Health Monitoring (as needed):**
- Use `plex-db-manager.sh check` for occasional health checks
- Use `plex.sh status` for service status verification
- Monitor system logs if issues are suspected
3. **When Issues Occur:**
- **Always start with read-only checks** (`plex-db-manager.sh check`)
- **Service issues first:** `plex.sh restart` before database interventions
- **Nuclear recovery as last resort** with proper validation
4. **Backup Verification:**
```bash
# Check Plex built-in backup status
ls -lath "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/"*.backup.*
# Verify backup location on NAS
ls -lah /mnt/share/media/backups/plex/
```
### What NOT to Do
**Don't re-enable daily custom backup scripts** (conflicts with Plex built-in)
**Don't enable 30-minute auto-repair schedules** (causes corruption)
**Don't use force-kill on Plex processes** (corrupts databases)
**Don't bypass safety checks** in scripts
**Don't run multiple repair operations simultaneously**
**Don't ignore failed service shutdowns** (wait for graceful exit)

- **Replacement**: Use `plex-db-manager.sh check` and `plex-db-manager.sh repair`
### `recover-plex-database.sh`
- **Reason**: Advanced recovery methods rarely worked effectively
- **Replacement**: Use `nuclear-plex-recovery.sh` for emergency situations
### `restore-plex.sh`
- **Reason**: Basic restoration functionality covered by other scripts
- **Replacement**: Use `nuclear-plex-recovery.sh` for backup restoration
### `icu-aware-recovery.sh`
- **Reason**: ICU collation issues addressed in main repair logic
- **Replacement**: Built into `plex-db-manager.sh` and `nuclear-plex-recovery.sh`
## Why These Were Retired
The original issue causing database corruption was identified as the **aggressive 30-minute auto-repair cron schedule**. With this fixed:
1. **Repair operations are now rarely needed**
2. **Simpler tools are more reliable** than complex multi-strategy repair scripts
3. **Manual intervention is preferred** over automated repair attempts
4. **Nuclear recovery** provides a clean last-resort option
## Access If Needed
These scripts are preserved for emergency use but are no longer maintained. If you need emergency access to advanced repair functionality:
```bash
# Emergency use only
./deprecated/plex-database-repair.sh repair /path/to/database.db
./deprecated/recover-plex-database.sh --auto
```
⚠️ **Note**: These scripts are no longer tested or supported. Use at your own risk.

# Consolidated Plex Database Management Script
################################################################################
#
# Author: Peter Wood <peter@peterwood.dev>
# Description: Consolidated database management functionality combining the best
# features from plex-database-repair.sh, recover-plex-database.sh,
# and nuclear-plex-recovery.sh into a single, safe interface.
#
# Features:
# - Read-only integrity checking
# - Progressive repair strategies (gentle to aggressive)
# - Service management with proper synchronization
# - Comprehensive logging and error handling
# - Manual intervention prompts for safety
#
# Usage:
# ./plex-db-manager.sh check # Read-only integrity check
# ./plex-db-manager.sh repair # Interactive repair
# ./plex-db-manager.sh repair --gentle # Gentle repair only
# ./plex-db-manager.sh repair --force # Aggressive repair
# ./plex-db-manager.sh nuclear # Nuclear recovery
#
# Exit Codes:
# 0 - Success
# 1 - Database issues detected (no repair attempted)
# 2 - Repair failed
# 3 - Service management failure
