umbrelOS can back up your entire Umbrel — your account, settings, files, apps, and data — to another Umbrel, a NAS, or an external USB drive. Backups are encrypted and run automatically every hour once set up.
When you need your data back, you can restore everything or use Rewind to recover specific files and folders from past backups.
Your backup location needs free space equal to at least twice the size of your backup.
Save your encryption password somewhere safe, like a password manager. You won't be able to see it again, and you won't be able to restore without it.
Once set up, umbrelOS backs up your data automatically on an hourly basis. It keeps:
Backups older than one year are automatically removed.
You can trigger a backup at any time from Settings > Backups > Configure. Select the backup location you want to back up to and click Back up now.
You can add more than one backup location for extra peace of mind. To add another, go to Settings > Backups > Configure and add a new backup location. Each location runs its own set of automatic backups.
By default, all your files and apps are included in backups. You can exclude specific files, folders, or entire apps from the Exclude from Backups section in Settings > Backups > Configure. Exclusions apply to all backup locations.
Some apps automatically exclude certain data like caches or logs that can be recreated or could cause issues if restored. These auto-exclusions are set by the app developer and can't be changed. You can see what each app auto-excludes in the Exclude from Backups section.
Keep in mind that if you exclude an app, it will still be reinstalled during a restore but its data won't be included — it will start fresh as if newly installed.
