JET_errKeyDuplicate, Illegal duplicate key and JET_dbErrDBTimeCorrupted

Hello,

I'm receiving some error messages with snapshots of the Exchange database on our Nimble volume. We take daily and weekly snapshots of our Exchange data drive (database files), and the Exchange log files drive.

We've purchased some software through Dell (MailRetriever from AppAssure) that can actually open the Exchange database file from the snapshot and restore a users mailbox or individual e-mail directly back to the users mailbox on the Exchange server.

However, we're getting both JET_errKeyDuplicate and JET_dbErrDBTimeCorrupted errors on the actual snapshot database. I'm not sure if the Nimble is taking bad snapshots, or corrupting the Exchange database, or not. 

It's hard to know if we had an Exchange server failure, if we restored one of these snapshots, whether it would work at all. Are there any steps I can take as to figuring out what to do? Why the snapshots seem to be getting corrupted? Or if they are even corrupted at all?

Thanks,

-R-
