I have an Exchange 2003 server with Backup Exec 2010 R3 on the same box. I have a daily backup job, which backs up Exchange to tape. This job succeeds each day. Once a week, I have a job set to back up our information store to an external hard drive for quick recovery. This backup to disk job fails. Here are the details in the job log:

Backup- \\Server\Microsoft Information Store\First Storage GroupV-79-57344-915 - Unable to complete the operation for the selected resource using the specified options. The following error was returned when opening the Exchange Database file: '-1022 There is a disk IO error. '
I have a similar setup in two other offices, the only difference being the BE Media Server is not on the same box as the Exchange server. Same build of BE, same external hard drive model and capasity, etc.
The log shows "There is a disk IO error", but the backup job runs for 11 hours, backing up 730 gigs before it fails. At the time of failure, it's attempting to catalog the mailboxes for GRT restores. So, to me, it seems unlikely to be a disk IO error.
Thanks,
Joel
