Check your drive for errors with a operating system disk utility such as Disk Utility or Disk Check and review the results. You may still be able to read or write to the drive even if errors are encountered, and the operating system disk utility may not detect some issues.
If the scan does not reveal any issues with the drive, relocate the backup archive to another location or drive using the steps below:
Please note, it is important to copy the archive using an application that can verify that files aren't corrupted during the copying process, such as TeraCopy or Rsync.
- Use an application like TeraCopy or Rsync, which can verify that files don't become corrupted during copying, to copy the archive from its existing location to the new location. To view a local archive’s current location, go to Destinations > Folders.
- Eject the drive from your computer.
- From Destinations > Folders remove the folder destination by clicking Remove backup archive, then Delete.
You will be prompted that your archive will be deleted. Provided that the drive is ejected it will not be deleted.
- Remount the drive to your computer.
- Attach the archive from the new location.
Backup resumes to the new location.
