The collective wisdom is that an offline defrag should not be performed
unless needed to free up disk space.

The regularly nightly online defrags are sufficient to maintain performance.

Hi there, have Exhange Standard 2000 sp3 on Server 2000 sp4. Have been
contemplating doing an offline defrag (we never have since the initial
install in 2002)
We use Veritas 9.1 with an Exchange Agent. We back up both the store and
the mailboxes. Have done some restores in past. An associate raised the
idea that it may be a good idea, on top of the Veritas backups, to close
all the Exchange services and then do a flat file backup of relevant
info. Can accommodate the down time to do so. 

Just wondering if any benefit? If the db was to be corrupted during the
restore, can I use the backed up flat files, or will there be some other
internal modifications which may prevent Exchange from 'recognizing' the
older db files? 

Thanks, D
