Take a backup
How do I back up my server?
Open Backups and create a backup; it saves the whole server (world, plugins, configs) as one archive you can restore or download.
Before you start: A free backup slot (12 GB plans and up include some; any plan can add slots in Billing).
Step by step
- Run save-all in the console so the world is fully written to disk.
- Open Backups and click Create Backup.
- Give it a clear name, like "before 1.21 update", so you can find it later.
- Wait until it shows as completed with a size; big servers take a few minutes. You can keep playing meanwhile.
- Download important backups too, so you have a copy that does not depend on the server.
- Take one before every risky change: version updates, new modpacks, big plugin changes, AI Builder experiments.
Check it worked: The backup is listed with a size and date.
Why it happens: Backups protect against griefing, bad updates and mistakes.
