+# Enhanced Plex Backup Script Documentation
+
+This document provides comprehensive documentation for the enhanced `backup-plex.sh` script. This advanced backup solution includes performance monitoring, parallel processing, intelligent notifications, WAL file handling, and automated testing capabilities.
+
+## Script Overview
+
+The enhanced script performs the following advanced tasks:
+
+1. **Performance Monitoring**: Tracks backup operations with JSON-based performance logging
+2. **Intelligent Backup Detection**: Only backs up files that have changed since last backup
+3. **WAL File Handling**: Properly handles SQLite Write-Ahead Logging files
+4. **Database Integrity Verification**: Comprehensive integrity checks with automated repair options
+5. **Parallel Processing**: Concurrent verification for improved performance
+6. **Multi-Channel Notifications**: Console, webhook, and email notification support
+7. **Checksum Caching**: Intelligent caching to avoid recalculating unchanged file checksums
+8. **Enhanced Service Management**: Safe Plex service management with progress indicators
+9. **Comprehensive Logging**: Detailed logs with color-coded output and timestamps
+10. **Automated Cleanup**: Configurable retention policies for old backups
+
+## Enhanced Features
+
+### Performance Tracking
+
+- **JSON Performance Logs**: All operations are timed and logged to `logs/plex-backup-performance.json`
+- **Performance Reports**: Automatic generation of average performance metrics
+- **Operation Monitoring**: Tracks backup, verification, service management, and overall script execution times
+
+### Notification System
+
+The script supports multiple notification channels:
+
+#### Console Notifications
+
+- Color-coded status messages (Success: Green, Error: Red, Warning: Yellow, Info: Blue)
+- Timestamped log entries with clear formatting
+
+#### Webhook Notifications
+
+```bash
+./backup-plex.sh --webhook=https://your-webhook-url.com/endpoint
+```
+
+Sends JSON payloads with backup status, hostname, and timestamps.
+
+#### Email Notifications
+
+```bash
+./backup-plex.sh --email=admin@example.com
+```
+
+Requires `sendmail` to be configured on the system.
+
+### WAL File Management
+
+The script now properly handles SQLite Write-Ahead Logging files:
+
+- **Automatic Detection**: Identifies and backs up `.db-wal` and `.db-shm` files when present
+- **WAL Checkpointing**: Performs `PRAGMA wal_checkpoint(FULL)` before integrity checks
+- **Safe Backup**: Ensures WAL files are properly backed up alongside main database files
+
+### Database Integrity & Repair
+
+Enhanced database management features:
+
+- **Pre-backup Integrity Checks**: Verifies database health before backup operations
+- **Automated Repair**: Optional automatic repair of corrupted databases using advanced techniques
+- **Interactive Repair Mode**: Prompts for repair decisions when issues are detected
+- **Post-repair Verification**: Re-checks integrity after repair operations
+
+### Parallel Processing
+
+- **Concurrent Verification**: Parallel backup verification for improved performance
+- **Fallback Safety**: Automatically falls back to sequential processing if parallel mode fails
+- **Configurable**: Can be disabled with `--no-parallel` for maximum safety
+
+## Command Line Options
+
+```bash
+Usage: ./backup-plex.sh [OPTIONS]
+
+Options:
+ --auto-repair Automatically attempt to repair corrupted databases
+ --check-integrity Only check database integrity, don't backup
+ --non-interactive Run in non-interactive mode (for automation)
+ --no-parallel Disable parallel verification (slower but safer)
+ --no-performance Disable performance monitoring
+ --webhook=URL Send notifications to webhook URL
+ --email=ADDRESS Send notifications to email address
+ -h, --help Show help message
+```
+
+## Configuration Files
+
+### Performance Log Format
+
+The performance log (`logs/plex-backup-performance.json`) contains entries like:
+
+```json
+[
+ {
+ "operation": "backup",
+ "duration_seconds": 45.3,
+ "timestamp": "2025-05-25T19:45:23-05:00"
+ },
+ {
+ "operation": "verification",
+ "duration_seconds": 12.8,
+ "timestamp": "2025-05-25T19:46:08-05:00"
+ }
+]
+```
+
+### Backup Tracking Log
+
+The backup tracking log (`logs/plex-backup.json`) tracks last backup times:
+
+```json
+{
+ "/var/lib/plexmediaserver/.../com.plexapp.plugins.library.db": 1732567523,
+ "/var/lib/plexmediaserver/.../Preferences.xml": 1732567523
+}
+```
+
+## Usage Examples
+
+### Basic Backup
+
+```bash
+./backup-plex.sh
+```
+
+Performs a standard backup with all enhanced features enabled.
+
+### Integrity Check Only
+
+```bash
+./backup-plex.sh --check-integrity
+```
+
+Only checks database integrity without performing backup.
+
+### Automated Backup with Notifications
+
+```bash
+./backup-plex.sh --non-interactive --auto-repair --webhook=https://notify.example.com/backup
+```
+
+Runs in automated mode with auto-repair and webhook notifications.
+
+### Performance-Optimized Backup
+
+```bash
+./backup-plex.sh --no-parallel --no-performance
+```
+
+Runs with parallel processing and performance monitoring disabled for maximum compatibility.
+
+## Automation and Scheduling
+
+### Cron Job Setup
+
+For daily automated backups at 2 AM:
+
+```bash
+# Edit crontab
+crontab -e
+
+# Add this line for daily backup
+0 2 * * * /home/acedanger/shell/backup-plex.sh --non-interactive --auto-repair --email=admin@example.com 2>&1 | logger -t plex-backup
+```
+
+### Systemd Service
+
+Create a systemd service for more control:
+
+```ini
+[Unit]
+Description=Plex Backup Service
+After=network.target
+
+[Service]
+Type=oneshot
+User=root
+ExecStart=/home/acedanger/shell/backup-plex.sh --non-interactive --auto-repair
+StandardOutput=journal
+StandardError=journal
+
+[Install]
+WantedBy=multi-user.target
+```
+
+### Systemd Timer
+
+Create a timer for regular execution:
+
+```ini
+[Unit]
+Description=Daily Plex Backup
+Requires=plex-backup.service
+
+[Timer]
+OnCalendar=daily
+Persistent=true
+
+[Install]
+WantedBy=timers.target
+```
+
+## Monitoring and Alerts
+
+### Performance Monitoring
+
+The script automatically tracks:
+
+- Backup operation duration
+- Verification times
+- Service start/stop times
+- Overall script execution time
+
+### Health Checks
+
+Regular health monitoring can be implemented by checking:
+
+```bash
+# Check last backup success
+jq -r '.[-1] | select(.operation == "total_script") | .timestamp' logs/plex-backup-performance.json
+
+# Check average backup performance
+jq '[.[] | select(.operation == "backup") | .duration_seconds] | add/length' logs/plex-backup-performance.json
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Permission Denied Errors**
+ - Ensure script runs with appropriate sudo permissions
+ - Check Plex file ownership and permissions
+
+2. **WAL File Warnings**
+ - Now handled automatically by the enhanced script
+ - WAL checkpointing ensures data consistency
+
+3. **Performance Issues**
+ - Use `--no-parallel` if concurrent operations cause problems
+ - Monitor performance logs for bottlenecks
+
+4. **Notification Failures**
+ - Verify webhook URLs are accessible
+ - Check sendmail configuration for email notifications
+
+### Debug Mode
+
+Enable verbose logging by modifying the script or using:
+
+```bash
+bash -x ./backup-plex.sh --check-integrity
+```
+
+## Testing Framework
+
+The script includes a comprehensive testing framework (`test-plex-backup.sh`):
+
+### Running Tests
+
+```bash
+# Run all tests
+./test-plex-backup.sh all
+
+# Run only unit tests
+./test-plex-backup.sh unit
+
+# Run performance benchmarks
+./test-plex-backup.sh performance
+```
+
+### Test Categories
+
+- **Unit Tests**: Core functionality verification
+- **Integration Tests**: Full system testing (requires Plex installation)
+- **Performance Tests**: Benchmarking and performance validation
+
+## Security Considerations
+
+### File Permissions
+
+- Backup files are created with appropriate permissions
+- Sensitive files maintain original ownership and permissions
+- Temporary files are properly cleaned up
+
+### Network Security
+
+- Webhook notifications use HTTPS when possible
+- Email notifications respect system sendmail configuration
+- No sensitive data is included in notifications
+
+### Access Control
+
+- Script requires appropriate sudo permissions
+- Backup locations should have restricted access
+- Log files contain operational data, not sensitive information
+
+## Backup Strategy
+
+The enhanced script implements a robust backup strategy:
+
+### 3-2-1 Backup Rule
+
+1. **3 Copies**: Original data + local backup + compressed archive
+2. **2 Different Media**: Local disk + network storage capability
+3. **1 Offsite**: Ready for remote synchronization
+
+### Retention Policy
+
+- Configurable maximum backup age (default: 30 days)
+- Configurable maximum backup count (default: 10 backups)
+- Automatic cleanup of old backups
+
+### Verification Strategy
+
+- Checksum verification for all backed up files
+- Database integrity checks before and after operations
+- Optional parallel verification for improved performance
+
+## Migration from Legacy Script
+
+To migrate from the original backup script:
+
+1. **Backup Current Configuration**: Save any custom modifications
+2. **Test New Script**: Run with `--check-integrity` first
+3. **Update Automation**: Modify cron jobs to use new options
+4. **Monitor Performance**: Check performance logs for optimization opportunities
+
+The enhanced script maintains backward compatibility while adding significant new capabilities.

+## Enhanced Features
+
+### Performance Tracking
+- **JSON Performance Logs**: All operations are timed and logged to `logs/plex-backup-performance.json`
+- **Performance Reports**: Automatic generation of average performance metrics
+- **Operation Monitoring**: Tracks backup, verification, service management, and overall script execution times
+
+### Notification System
+The script supports multiple notification channels:
+
+#### Console Notifications
+- Color-coded status messages (Success: Green, Error: Red, Warning: Yellow, Info: Blue)
+- Timestamped log entries with clear formatting
+
+#### Webhook Notifications
+```bash
+./backup-plex.sh --webhook=https://your-webhook-url.com/endpoint
+```
+Sends JSON payloads with backup status, hostname, and timestamps.
+
+#### Email Notifications
+```bash
+./backup-plex.sh --email=admin@example.com
+```
+Requires `sendmail` to be configured on the system.
+
+### WAL File Management
+The script now properly handles SQLite Write-Ahead Logging files:
+- **Automatic Detection**: Identifies and backs up `.db-wal` and `.db-shm` files when present
+- **WAL Checkpointing**: Performs `PRAGMA wal_checkpoint(FULL)` before integrity checks
+- **Safe Backup**: Ensures WAL files are properly backed up alongside main database files
+
+### Database Integrity & Repair
+Enhanced database management features:
+- **Pre-backup Integrity Checks**: Verifies database health before backup operations
+- **Automated Repair**: Optional automatic repair of corrupted databases using advanced techniques
+- **Interactive Repair Mode**: Prompts for repair decisions when issues are detected
+- **Post-repair Verification**: Re-checks integrity after repair operations
+
+### Parallel Processing
+- **Concurrent Verification**: Parallel backup verification for improved performance
+- **Fallback Safety**: Automatically falls back to sequential processing if parallel mode fails
+- **Configurable**: Can be disabled with `--no-parallel` for maximum safety
+
+### Command Line Options
+
+```bash
+Usage: ./backup-plex.sh [OPTIONS]
+
+Options:
+ --auto-repair Automatically attempt to repair corrupted databases
+ --check-integrity Only check database integrity, don't backup
+ --non-interactive Run in non-interactive mode (for automation)
+ --no-parallel Disable parallel verification (slower but safer)
+ --no-performance Disable performance monitoring
+ --webhook=URL Send notifications to webhook URL
+ --email=ADDRESS Send notifications to email address
+ -h, --help Show help message
+```

+- [ ] **Disk Space**: Ensure backup location has 2x current Plex database size available
+
+## Testing Phase
+
+### 1. Run Unit Tests
+
+```bash
+cd /home/acedanger/shell
+./test-plex-backup.sh unit
+```
+
+**Expected Result**: All 9 tests should pass (100% success rate)
+
+### 2. Run Integration Tests
+
+```bash
+cd /home/acedanger/shell
+./integration-test-plex.sh
+```
+
+**Expected Result**: All integration tests should pass
+
+### 3. Test Dry Run
+
+```bash
+# Test integrity check only (non-destructive)
+sudo ./backup-plex.sh --check-integrity --non-interactive
+```
+
+**Expected Result**: Should complete without stopping Plex or creating backups
+
+### 4. Test Notification Systems
+
+#### Webhook Testing
+```bash
+# Replace with your actual webhook URL
+sudo ./backup-plex.sh --check-integrity --webhook=https://your-webhook-endpoint.com/test
+```
+
+#### Email Testing
+```bash
+# Replace with your email address
+sudo ./backup-plex.sh --check-integrity --email=admin@yourdomain.com
+```
+
+## Production Deployment Steps
+
+### 1. Initial Backup Test
+
+```bash
+# Create a manual backup during maintenance window
+sudo ./backup-plex.sh --non-interactive
+```
+
+**Verify**:
+- [ ] Plex service stopped and restarted properly
+- [ ] Backup files created in `/mnt/share/media/backups/plex/YYYYMMDD/`
+- [ ] Log files updated in `/mnt/share/media/backups/logs/`
+- [ ] Performance log created if enabled
+- [ ] Notifications sent if configured
+
+### 2. Validate Backup Integrity
+
+```bash
+# Run validation on the created backup
+./validate-plex-backups.sh --report
+```
+
+### 3. Test Restore Process (Optional)
+
+```bash
+# In a test environment, verify restore functionality
+./restore-plex.sh --list
+./restore-plex.sh --validate YYYYMMDD
+```
+
+## Automated Scheduling
+
+### 1. Cron Configuration
+
+Create a cron job for automated backups:
+
+```bash
+# Edit crontab for root user
+sudo crontab -e
+
+# Add entry for daily backup at 2 AM
+0 2 * * * /home/acedanger/shell/backup-plex.sh --non-interactive --webhook=https://your-webhook.com/plex-backup 2>&1 | logger -t plex-backup
+```
+
+### 2. Systemd Timer (Alternative)
+
+Create systemd service and timer files:
+
+```bash
+# Create service file
+sudo tee /etc/systemd/system/plex-backup.service > /dev/null << 'EOF'
+[Unit]
+Description=Plex Media Server Backup
+After=network.target
+
+[Service]
+Type=oneshot
+User=root
+ExecStart=/home/acedanger/shell/backup-plex.sh --non-interactive
+StandardOutput=journal
+StandardError=journal
+EOF
+
+# Create timer file
+sudo tee /etc/systemd/system/plex-backup.timer > /dev/null << 'EOF'
+[Unit]
+Description=Run Plex backup daily
+Requires=plex-backup.service
+
+[Timer]
+OnCalendar=daily
+Persistent=true
+RandomizedDelaySec=30m
+
+[Install]
+WantedBy=timers.target
+EOF
+
+# Enable and start timer
+sudo systemctl daemon-reload
+sudo systemctl enable plex-backup.timer
+sudo systemctl start plex-backup.timer
+```
+
+## Monitoring and Maintenance
+
+### 1. Log Monitoring
+
+Monitor backup logs for issues:
+
+```bash
+# Check recent backup logs
+tail -f /mnt/share/media/backups/logs/plex-backup-$(date +%Y-%m-%d).log
+
+# Check system logs for backup service
+sudo journalctl -u plex-backup.service -f
+```
+
+### 2. Performance Monitoring
+
+```bash
+# View performance trends
+jq '.[] | select(.operation == "full_backup") | {timestamp, duration_seconds}' \
+ /home/acedanger/shell/logs/plex-backup-performance.json | tail -10
+```
+
+### 3. Regular Validation
+
+Schedule weekly backup validation:
+
+```bash
+# Add to crontab
+0 3 * * 0 /home/acedanger/shell/validate-plex-backups.sh --report --fix 2>&1 | logger -t plex-backup-validation
+```
+
+## Troubleshooting Guide
+
+### Common Issues
+
+#### 1. Permission Denied Errors
+```bash
+# Fix script permissions
+chmod +x /home/acedanger/shell/*.sh
+
+# Fix backup directory permissions
+sudo chown -R $(whoami):$(whoami) /mnt/share/media/backups/
+```
+
+#### 2. Plex Service Issues
+```bash
+# Check Plex service status
+sudo systemctl status plexmediaserver
+
+# Manually restart if needed
+sudo systemctl restart plexmediaserver
+```
+
+#### 3. Insufficient Disk Space
+```bash
+# Check available space
+df -h /mnt/share/media/backups/
+
+# Clean old backups manually if needed
+./backup-plex.sh # Script will auto-cleanup based on retention policy
+```
+
+#### 4. Database Integrity Issues
+```bash
+# Run integrity check only
+sudo ./backup-plex.sh --check-integrity --auto-repair
+
+# Manual database repair if needed
+sudo ./backup-plex.sh --auto-repair
+```
+
+### Performance Optimization
+
+#### 1. Parallel Processing
+- Enable parallel verification for faster backups (default: enabled)
+- Disable with `--no-parallel` if experiencing issues
+
+#### 2. Performance Monitoring
+- Disable with `--no-performance` if not needed
+- Monitor trends to optimize backup timing
+
+#### 3. Notification Optimization
+- Use webhooks instead of email for faster notifications
+- Configure webhook endpoints with proper error handling
+
+## Security Considerations
+
+### 1. File Permissions
+```bash
+# Secure backup files
+chmod 600 /home/acedanger/shell/logs/plex-backup*.json
+chmod 700 /mnt/share/media/backups/plex/
+```
+
+### 2. Webhook Security
+- Use HTTPS endpoints for webhooks
+- Implement webhook signature verification if possible
+- Avoid including sensitive data in webhook payloads
+
+### 3. Access Control
+- Limit script execution to authorized users
+- Consider using dedicated backup user account
+- Regularly audit file access permissions
+
+## Backup Retention Strategy
+
+The script automatically manages backup retention:
+
+- **Default**: Keep 10 most recent backups
+- **Age-based**: Remove backups older than 30 days
+- **Configurable**: Modify `MAX_BACKUPS_TO_KEEP` and `MAX_BACKUP_AGE_DAYS` in script
+
+## Recovery Planning
+
+### 1. Backup Restoration
+```bash
+# List available backups
+./restore-plex.sh --list
+
+# Restore specific backup
+sudo ./restore-plex.sh --restore YYYYMMDD
+```
+
+### 2. Emergency Procedures
+1. Stop Plex service: `sudo systemctl stop plexmediaserver`
+2. Backup current data: `./restore-plex.sh --backup-current`
+3. Restore from backup: `sudo ./restore-plex.sh --restore YYYYMMDD`
+4. Start Plex service: `sudo systemctl start plexmediaserver`
+
+## Success Metrics
+
+Monitor these metrics to ensure backup system health:
+
+- [ ] **Backup Success Rate**: >99% successful backups
+- [ ] **Backup Duration**: Consistent timing (tracked in performance logs)
