There have been diskussion on this earlier, but thes questions are closed, so I try again.
We use Backup Exec 12.5. We use Backup-to-disk and Dupplicate.
The Bacup-to-disk files is set to maximum of 4Gb/file. We are backup up about 850GB data.
When the backup has run about two weeks, it is slowing down pretty much (normally 8 hours each, but after two weeks about 12 hours). When we erase the files in the Backup-to-disk (only the files, not the folder), it is getting recreated at next backup and is speeding up again.
We can see that the disk is very fragmentet, but a defrag does not help very much - only an erase/recreation.
Is there a better way?
(NB: earlier, we had the Bacup-to-disk files set to maximum of 100Gb/file - but with 4gb/file it is fastelr...
