I used to do a full backup every night but that was starting to take too long to complete and I found it was still running in the morning when I came into work. Ive now changed to a full backup on a Friday night and differential backups during the week.
We use backup exec 12.5 and the job rate of the full backup is about 1gb/min. The backup rate for the differential backup is only 200mb/min. Is this normal for differential backups to be slower?
