backup problem..

[mrCide]

We have 2000 server with veritas backup 8.6 i believe. Daily backups were running fine except they started exceeding the amount a single tape would store. So, I had users clean out their mailboxes/deleted items/etc. and cleaned out shared files that weren't needed anymore (all on the server, which also runs exchange).

Now backups get about a gig through and I get this:

Storage device "QUANTUM 1" reported an error on a request to write data to media.

Error reported:
The request could not be performed because of an I/O device error.
^ ^ ^ ^ ^
Backup completed on 5/22/2003 at 1:41:52 AM.

about 10 minutes into the 'Microsoft Exchange Mailboxes' portion of the backup. It's happened 2 days in a row now (never had this problem prior).

Anyone have any ideas?

First: Do you only have 1 quantum drive and no tape library? (DLT? SDLT? LTO?)

Second: If you're getting and I/O error, that's probably a SCSI issue. You might want to try reinstalling the drivers or updating them if there's a newer one. Check for any firmware releases for your hardware while you're at it (scsi controller and backup drive). Despite all that, a reboot should fix it unless the hardware is actually failing or the tape is bad, but normally the software can detect failed tapes.

Well see we've had proper backups for over 2 months, and the moment i cleaned some exchange mailboxes i started having this problem.

After a few days of the same problem at the same place (during an exchange backup) and starting to get exchange fragmented please restart it, i rebooted.

I got one good backup, yesterday, but today's failed aat the same spot again with the same error. There has to be a reason for this and a way to fix it...

anyone?

why am i getting errors now only after cleaning out exchange? I got one successful backup after a reboot but It failed at the exchange mailboxes, then once during the C$ backup.. *sigh*
