If the disk is full, stop the user backup with an error message, and importantly: skip to the next user.

I have backups set to a backup server, and I noticed that my newest backups of my biggest users are not as big as it used to be. In fact, the old backup 2 weeks ago was 36GB, and the new one is 23GB, which is the exact same size as the disk space available at the time. Giving my disk extra space -by deleting stuff on the server- the backup was 36GB again.

This frustrates me because when I tried restoring a backup on a different server as a test, it came up with an error saying "Unexpected EOF" while the backup was a success. After giving the extra space and using the new backup from the backup server, the restore was actually succesful this time.
