⚙️ Advanced Configuration

File Exclusions

Exclude large folders to reduce backup size:

backup:
  exclude:
    - "logs/*.gz"
    - "logs/*.log.*"
    - "plugins/dynmap/web/tiles/**"
    - "plugins/BlueMap/web/**"
    - "**/cache/**"

Streaming Mode

Compress and upload simultaneously (no local file):

upload:
  streaming-compression: true  # Requires SFTP or FTPS

Benefits:

• ⚡ Faster overall backup time
• 💾 No local disk space usage
• 🔄 Real-time progress updates

Limitations:

• ⚠️ Retention policies not supported in streaming mode
• 📍 Requires SFTP or FTPS destination

Performance Tuning

Optimize for your server:

performance:
  max-memory-mb: 512          # Maximum RAM usage
  max-buffer-kb: 8192         # Buffer size for compression
  gc-after-zip: true          # Free memory after compression
  cleanup-after-backup: true  # Full memory cleanup
  tps-threshold: 18.0         # Slow down if TPS drops below this

Retention Policies

Automatically delete old backups:

retention:
  enabled: true
  keep-last: 7                # Keep only the last 7 backups
  filename-prefix: "backup-"  # Filter files by prefix
  filename-suffix: ".tar.zst" # Filter files by extension

🔐 SSH Key Authentication

For enhanced security, use SSH keys instead of passwords:

1. Generate an SSH key:

   ssh-keygen -t ed25519 -f ~/.ssh/minecraft_backup
   

2. Add the public key to your server:

   ssh-copy-id -i ~/.ssh/minecraft_backup.pub user@your-server.com
   

3. Configure Ancient-Backup:

   sftp:
     private-key-path: "plugins/Ancient-Backup/minecraft_backup"
     password: ""  # Leave empty when using key auth

📊 Performance

Benchmark Results

Tested on a 10GB Minecraft server with Paper 1.21.10:

Method	Time	CPU Usage	Disk I/O
ZSTD Level 1	2m 15s	Low	Minimal
ZIP Level 1	6m 30s	Medium	Medium
ZIP Level 9	12m 45s	High	High

Streaming Mode: Reduces total backup time by 30-40% compared to traditional mode.

🐛 Troubleshooting

No progress output?

• Ensure you're using the latest version
• Check that your upload destination is properly configured
• Look for error messages in the console

Upload fails?

• Use /abackup uploadlast to retry
• Check network connectivity and credentials
• Enable debug logging in config.yml

Server lags during backup?

• Lower performance.max-buffer-kb to reduce memory usage
• Reduce backup.zip-level to use less CPU
• Set performance.tps-threshold higher to trigger throttling sooner

Discord notifications not working?

• Verify webhook URL is correct
• Test webhook manually using curl or online tools
• Check that discord.enabled: true
