Time Machine backup keeps failing or won't complete
Time Machine is failing because the backup disk is disconnected, full, or not recognized. Check that the drive is plugged in and has enough space, then try the backup again. If it still fails, erase the backup and start fresh.
Time Machine backs up your entire Mac to an external drive so you never lose your files. If backups keep failing, the drive is disconnected, the connection is unstable, or the disk is full. We'll check the connection, free up space, and restart the backup.
- ✓Have your backup drive plugged into a power outlet if needed
- ✓Make sure your Mac is plugged in during backup
- ✓Don't plan to put your Mac to sleep during troubleshooting

Skip, I just want a technicianCommon mistakes to avoid
- Unplugging the drive during a backup. This corrupts the backup and you can need to erase and restart
- Allowing your Mac to sleep during backup. Always keep it awake until backup is complete
Signs you need professional help
- If Time Machine still won't complete backups after restarting your Mac and backup drive, and you have confirmed the drive is not full, the drive itself can be failing.
