Thread: Differential-Incremental Jobs are the size of Full Backup

  1. Differential-Incremental Jobs are the size of Full Backup


    After a little research I found two items that might cause this: True Image
    Backup and Backup based on Timestamp. However, we are not doing either of
    these, yet the differential-incremental backups are the same size as a full
    backup, any ideas?

    This could happen if the Use_Archive_Bit registry key is 'NO'.

    This key is set to "YES". Would anything else cause this?

    Does the scheduling class that the 'differential' job is in have a 'full'
    schedule in it also? Did someone misconfigure the underlying job type in
    the scheduler? Is the clients service running as system/or a user with rights
    to change the archive bit (check logs for client when a full runs)?

    What type of system are you trying to back up? I know that Backup Exec is
    incapable of doing real Incremental and Differential backups of Unix (at
    least, to NT) and that the user must set up Daily backups instead. I'm hoping
    that NetBackup solves this problem, so I'm scouring this newsgroup to see
    what I can find.

    Maybe we can be of help to each other.
