- `MAX_BACKUPS_TO_KEEP=10`: Keep maximum of 10 backup sets - `MAX_BACKUPS_TO_KEEP=10`: Keep maximum of 10 backup sets
- `BACKUP_ROOT`: Location for backup storage - `BACKUP_ROOT`: Location for backup storage
- `LOG_ROOT`: Location for backup logs - `LOG_ROOT`: Location for backup logs
### Backup Strategy ### Recommended Backup Strategy
The system implements a robust 3-2-1 backup strategy: Both systems implement a robust backup strategy following industry best practices:
1. **3 copies**: Original data + local backup + compressed archive **For Media Files:**
2. **2 different media**: Local disk + network storage
3. **1 offsite**: Consider syncing to remote location
For offsite backup, add to cron: 1. **Daily incremental backups** with parallel processing for speed
2. **Weekly verification** of backup integrity
3. **Monthly cleanup** of old backups based on retention policies
4. **Quarterly offsite sync** for disaster recovery
**For Plex Database:**
1. **Daily full backups** with service-aware operations
2. **Immediate validation** after each backup
3. **Weekly comprehensive reports** on backup health
4. **Monthly testing** of restore procedures
### Offsite Backup Integration
For comprehensive disaster recovery, sync backups to remote locations:
```bash ```bash
# Sync backups to remote server daily at 6 AM # Sync media backups to remote server daily at 5 AM
0 5 * * * rsync -av /mnt/share/media/backups/media/ user@remote-server:/backups/media/
# Sync Plex backups to remote server daily at 6 AM
0 6 * * * rsync -av /mnt/share/media/backups/plex/ user@remote-server:/backups/plex/ 0 6 * * * rsync -av /mnt/share/media/backups/plex/ user@remote-server:/backups/plex/
``` ```

# Retention settings
MAX_BACKUP_AGE_DAYS=30 # Delete backups older than 30 days
MAX_BACKUPS_TO_KEEP=10 # Keep only 10 most recent backups
# Directory settings
BACKUP_ROOT="/mnt/share/media/backups"
LOG_ROOT="/mnt/share/media/backups/logs"
# Feature toggles
PARALLEL_BACKUPS=true # Enable parallel execution
VERIFY_BACKUPS=true # Enable backup verification
PERFORMANCE_MONITORING=true # Track performance metrics
```
### Services Configuration
The script automatically detects and backs up these services:
| Service | Container Path | Backup Content |

│ ├── db/
│ └── settings.json
└── backup_20250524/
```
## Notifications
The script supports webhook notifications (compatible with ntfy.sh and similar services):
```bash
# Default webhook
WEBHOOK_URL="https://notify.peterwood.rocks/lab"
# Custom webhook via command line
./backup-media.sh --webhook "https://your-notification-service.com/topic"
```
Notification includes:
- Backup status (success/failure)
- Number of successful/failed services
- Total execution time
- Hostname for identification
## Performance Monitoring
When enabled, the script tracks:
- Individual service backup duration
- Overall script execution time
- Timestamps for performance analysis
- JSON format for easy parsing and graphing
Example performance log entry:
```json
{
"timestamp": "2025-05-25T14:30:22-05:00",
"operation": "backup_sonarr",
"duration": 45,
"hostname": "media-server"
}
```
## Error Handling
The script provides robust error handling:
1. **Container Health**: Checks if Docker containers are running
2. **Disk Space**: Verifies sufficient space before starting
3. **Docker Access**: Ensures Docker daemon is accessible
4. **Verification**: Optional integrity checking of backups
5. **Graceful Failures**: Continues with other services if one fails
## Integration
### Cron Job
Add to crontab for automated daily backups:
```bash
# Daily at 2 AM
0 2 * * * /home/acedanger/shell/backup-media.sh >/dev/null 2>&1
# Weekly full backup with verification
0 3 * * 0 /home/acedanger/shell/backup-media.sh --verify
```
### Monitoring
Use the JSON logs for monitoring integration:
```bash
# Check last backup status
jq '.sonarr.status' /home/acedanger/shell/logs/media-backup.json
# Get performance metrics
jq '.[] | select(.operation == "full_media_backup")' /home/acedanger/shell/logs/media-backup-performance.json
```
## Troubleshooting
### Common Issues
1. **Container Not Running**
```
WARNING: Container 'sonarr' is not running
```
- Verify the container is running: `docker ps`
- Start the container: `docker start sonarr`
2. **Permission Denied**
```
ERROR: Backup failed for sonarr
```
- Check Docker permissions
- Verify backup directory permissions
- Ensure script has execute permissions
3. **Disk Space**
```
ERROR: Insufficient disk space
```
- Free up space in backup directory
- Adjust `MAX_BACKUP_AGE_DAYS` for more aggressive cleanup
- Run manual cleanup: `find /mnt/share/media/backups -mtime +7 -delete`
### Debug Mode
For troubleshooting, run with verbose output:
```bash
# Enable debugging
bash -x ./backup-media.sh --dry-run
# Check specific service
docker exec sonarr ls -la /config/Backups/scheduled
```
## Comparison with Original Script
| Feature | Original | Enhanced |
| -------------- | --------------- | --------------------------------- |
| Error Handling | Basic | Comprehensive |
| Logging | Simple text | Multi-format (text/JSON/markdown) |
| Performance | No tracking | Full metrics |
| Verification | None | Optional integrity checking |
| Execution | Sequential only | Parallel and sequential modes |
| Notifications | Basic webhook | Enhanced with statistics |
| Cleanup | Manual | Automatic with retention policies |
| Safety | Limited | Dry-run, pre-flight checks |
| Documentation | Minimal | Comprehensive help and docs |
## Security Considerations
- Script runs with user permissions (no sudo required for Docker operations)
- Backup files inherit container security context
- Webhook URLs should use HTTPS for secure notifications
- Log files may contain sensitive path information
- JSON logs are readable by script owner only
## Future Enhancements
Potential improvements for future versions:
- Database integrity checking for specific services
- Compression of backup archives
- Remote backup destinations (S3, rsync, etc.)
- Backup restoration functionality
- Integration with monitoring systems (Prometheus, etc.)
- Encrypted backup storage
- Incremental backup support
