Diskeeper may be worth a look, HOWEVER, I haev had MAJOR issues with this
product trying to run after a backup as it appeared to clear the archive
attribute.
Fragmentation is an issue, so where poss, try to defrag when backups are not
required or may JUST before a FULL Backup (that way keeps the archive bit !)
Good Luck

Subject: RE: [Veritas-bu] Windows File Fragmentation
Yes, file fragmentation does cause backups to perform slowly, especially on
drives housing databases or many small files. However, we found here that
the slowness caused by fragmentation was only 10% of our reason for slow
backups and that 90% pertained to network configuration. I guess what I'm
getting at is that, if you mean the backup used to take 5 hours and now it
takes 6, then likely fragmentation is an issue. However, if your backup
times are 20 hours and they should be five, then you've got bigger issues
than running scandisk on your hard drives.

I have a database volume that is 95% fragmented. I'm getting poor
performance on my backups.
In your experience, has file fragmentation caused slow performance on
Windows systems?
Thanks
Karl
