Problem backing up Exchange datastore
Posted on 2007-03-29
We are running Exchange 2003 on Server 2003. In performing a backup (using ntbackup, as well as Veritas Backup Exec V10.D) , the operation fails roughly at the same place byte-wise. The event log error, and ntbackup logfile shows:
Error: The device reported an error on a request to write data to media.
Error reported: Unknown error.
There may be a hardware or media problem.
Please check the system event log for relevant failures.
The operation was ended.
Backup completed on 3/29/2007 at 10:01 AM.
Time: 6 minutes and 21 seconds
Error: xxxxMAIL\Microsoft Information Store\First Storage Group is not a valid drive, or you do not have access.
