I have not had a successful backup on our new Windows 2003 standard server using Backup exec 9.1.
Tape device is an EXABYTE VXA-2 Tapes are all brand new. After the job fails the tape needs to be reformatted, renamed and re-added to the media set.
Updated veritas device drivers. Installed relevant Veritas updates. Also uninstalled and reinstalled Backup Exec.
The backup fails after around 15mins.
Error messages in the job log are: ******************* Backup Set Detail Information Storage device "EXABYTE 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.
************************* Job Completion Status Job ended: Wednesday, 2 February 2005 at 9:57:10 AM Completed status: Failed Final error: 0x45d - The request could not be performed because of an I/O device error.
