Differential Backup
This choice means all files that
have changed since the last full (complete)
backup are saved in this backup method. Typically this is done
once a week concluding with a full backup of
the week(separate process) and then when the next week starts,
the cycle (schedule) of backups of all files that have
changed since this most recent last full backup begins
again. The maximum number of backup sessions that occur in a
week for this method is five, assuming that users
work on the system five days a week. The archive bit is not
touched (reset) during each backup.
Restoring Differential Backups
This method is slower, but
not as slow as a full backup. This method is safer than an incremental
backup but not as easy as a full backup to restore. When
you need to restore you must use a full set (all of them!) of
the full (complete) backup tapes, and
the most current differential backup tape.
