You need to read some books. You have to back up the Microsoft Exchange Information Store as an object, not as an .edb file.

Tried backing up the *edb file, but am told 'file in use' and won't backup. With the individual backup (the only way I've gotten it to run), I have been able to restore users's files (someone deleted a subfolder of their email), etc. For the type of restores that I've needed to do, it seemed to be working fine. Is there a better way (or a pointer to types I could examine) to be backing up? And thanks for the explanation, that certainly make sense. At 05:32 PM 6/21/2004, Ben Winzenz wrote: >Absolutely.
