Oh, ick. Yes, I skipped past that, that this started AFTER a restore. Ugh, I went through this myself about six years ago. I had no recourse but to try eseutil, as the backups were incomplete. My advice on that remains the same - run eseutil hard repair on a COPY of the database, to make sure the cure is not worse than the disease. But if something has introduced corruption in your database that won't allow it to complete a backup on that storage group, my inclination would be to move the mailboxes and public folders to another, clean, storage group and database, and kill the corrupted one.
-1018 does indeed indicate that there WAS hardware failure, but if you're still getting it once the hardware issue is resolved, then it's database corruption.

However, maybe you a missed that part of my message. We have restored from the last successful online backup and since then we are getting -1018 errors. No issues prior to the restore. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Hawkins, Geni P Posted At: Wednesday, September 13, 2006 3:23 PM Posted To: Exchange Mailing List Conversation: Problem performing an online backup Subject: RE: Problem performing an online backup I remember error -1018. That's database corruption caused by hardware failure. Restore from an online backup done before the original problem is definitely your best bet, I'd say. Been there, done that. Hated it. Your last resort, if a good online backup is not available, is to run hard repair on a COPY of the database. The reason I say on a copy is because hard repair can do ... um ... unanticipated things to the database, and it might be a cure worse than the solution. Another option, depending on database size, would be to move mailboxes to a different mail store/storage group, move everything off the corrupted store, and kill it. But a restore from a pre-corruption backup is definitely the best bet.

Using onboard Raid controller (Smart Array 6i) Single Site, Single Server supporting about 110 users. The server has been running fine for a number of weeks and has been running normal backups successfully 5 days a week. During a hardware change of a completely different system, an external tape backup unit was inadvertently plugged into the external SCSI port on this server. There was a SCSI ID conflict and the SCSI controller stopped responding and resulted with the server blue-screening. Upon reboot, the server started but the stores (private and public) would not mount as they appear corrupted. We had a recent full online backup that we restored. The restore reported that it completed successfully and it replayed all the logs. The stores mounted and everything looked peachy. However, the next online backup fails. The first event to be logged is 474: Information Store (3384) First Storage Group: The database page read from the file "F:\MDBData\priv1.edb" at offset 50864988160 (0x0000000bd7ca2000) (database page 12418209 (0xBD7CA1)) for 4096 (0x00001000) bytes failed verification due to a page checksum mismatch. The expected checksum was 2278640537 (0x0000000087d14b99) and the actual checksum was 53335803808533401 (0x00bd7ca187d14b99). The read operation will fail with error -1018 (0xfffffc06). If this condition persists then please restore the database from a previous backup. This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem. There are 16 more just like this and then event 217: Information Store (3384) First Storage Group: Error (-1018) during backup of a database (file F:\MDBData\priv1.edb). The database will be unable to restore. Then event 222: Information Store (3384) First Storage Group: Ending the backup of the file F:\MDBData\priv1.edb. Not all data in the file has been read (read 50864979968 bytes out of 50865057792 bytes). Then 8001: End Backup of 'STORK\Microsoft Information Store\First Storage Group' 'Warnings or errors were encountered.' We placed a call to MS Support and they tell us we have a hardware failure. But this doesn't make sense to me unless connecting this tape drive actually damaged the controller or a drive, but I never experienced or even heard of such a thing. My question to the list is this: What needs to be done to correct the problem? Many years ago I had a hardware failure on Exchange 5.5. I added a second server and moved all my mailboxes there. I then deleted the corrupted store, restarted Exchange to create a new empty store. I then moved all the mailboxes back and my errors were gone. Can this same type of procedure work with Exchange 2003. Are there other methods? Please let me know if you need more information. Thanks.
