|
||||
|
||||
The enhanced media backup script includes configurable parameters at the top of the file:
|
||||
|
||||
- `PARALLEL_JOBS=4`: Number of parallel rsync processes
|
||||

|
||||
|
||||
### 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
|
||||
2. **2 different media**: Local disk + network storage
|
||||
3. **1 offsite**: Consider syncing to remote location
|
||||
**For Media Files:**
|
||||
|
||||
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
|
||||
# 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/
|
||||
```

## 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
