Data Safety: Auto-Savings

Terraria worlds are primarily saved to disk upon a clean server shutdown or during a scheduled auto-save event. If a server experienced a crash due to a memory overflow or a faulty plugin, any progress made since the last save point could be permanently lost.

Optimizing the Save Interval

By default, many TShock installations save every 60 minutes. We recommend reducing this significantly for active multiplayer servers.
  1. Open Configuration: Locate /tshock/config.json via SFTP.
  2. Backup Interval: Change "BackupInterval": 60 to 15 (minutes).
  3. Crash Safety: Ensure "SaveWorldOnCrash": true is set. This attempts to write the world file to disk immediately if the server process detects an impending failure.

​
Restoring from a Backup

If your main .wld file becomes corrupted:
  1. Stop the server.
  2. Navigate to /tshock/backups/.
  3. Locate the most recent ZIP archive of your world.
  4. Extract the .wld file and upload it to /Saves/Worlds/, replacing the corrupted original.
  5. Start the server.
