Back up and restore your Terraria world

Use scheduled and on-demand backups and restore compatible world and mod data.

2 min read • Updated 25 September 2026

Backup coverage

Each Terraria plan includes daily automatic backups and the same on-demand storage allowance as the corresponding Minecraft plan. Backups include the service files and supported service database data. Worlds, modded text.twld companion files, installed mods and configuration should be restored together.

Open Server → Backups to review completed backups, create an on-demand backup, download one or restore it. A queued or running backup is not a completed recovery point. Check its final status and reported errors. The quota shown is shared according to your plan; delete unneeded on-demand snapshots when necessary.

Before changes

Create a backup before upgrading or downgrading Terraria/tModLoader, replacing a world, changing mod packs or deleting databases. Also download an independent copy of valuable world files.

Restore

Choose a compatible completed backup and follow the restore confirmation. Restoring replaces current service data. Select a pre-restore safety backup when offered if you need a way back. Do not upload or edit files during a restore. Wait for the restore task to finish, start the server if needed, inspect Console and join with the matching client and mods.

A backup made with one mod set may require that same set to load correctly. Retaining a world file alone cannot recover content removed by loading it without its mods.

Terraria saves and briefly stops while a backup copies the world files, then restarts automatically if it was running. Uploading the backup continues after the server restarts. Restores also stop the server before replacing files. Plan for a brief player disconnect; stopped servers stay stopped.
