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.=20
In your experience, has file fragmentation caused slow performance on
Windows systems?=20
Thanks=20
