Problem Resolution

After troubleshooting the problem for an hour and being pressed for time, we ended up calling Symantec since we had a support contract. What ended up being the problem was because we were not using the R2 version. Here’s the version we were initially using:

Symantec

Backup Exec 2010

Media Server: Version 13.0 Rev. 2896 (64-bit)

Administration Console: Version 13.0 Rev. 2896 (64-bit)

Desktop and Laptop Option: Version 3.1 Rev. 3.42.44a

Once we upgraded to the R2 version, the backups began to work:

Symantec

Backup Exec 2010 R2

Media Server: Version 13.0 Rev. 4164 (64-bit)

Administration Console: Version 13.0 Rev. 4164 (64-bit)
