I have a problem with my Exchange server backups. It can't backup faster
than 15MB/Minute. This has decresed the last couple of months down to this
extremely low level. I need help!!

My setup:

IBM x225 2.67Ghz
HP Surestore DAT 20/40 tapedrive
RAID 5 (I know that the best setup is a RAID 1/5 but finances put a stop to
that :-(.)
System/Installation on C:
Datafiles on D:
Windows 2000 Srv
Exchange 2000

I recently defraged my drives but should I take the Exchange server offline
and do a "cold" defrag of the database?
