Settings & keep-time · Advanced, self-backup and Demo Mode
Why does Self-backup say my external drive isn't connected?
Short answer: Self-backups live on your external drive, so they can only be listed or made while it's connected. Plug the drive in and click Refresh in Settings → Advanced → Self-backup.
Self-backups are kept on your external drive, so the list can only be shown — and new backups made — while that drive is connected. Plug it in, then click Refresh in Settings → Advanced → Self-backup.
If you click Backup now with the drive away, you'll see a short note instead of a backup. The daily backup catches up once the drive is back.
