Our organisation is using Backup Exec 2010 R3 on a Windows 2008 R2 Server Standard set up. The system is fully patched. Our backups are going to tape and an external drive. Both devices are showing up in the devices tab, and are visible. Neither is showing as paused, nor are they showing any immediate warning signals. I also tested the log in credentials for all our backup jobs. But the backups have been failing consistently for a few weeks now. The errors are all coming up as the media being offline.
When I checked the media, I clicked on the Devices tab, and under the General Tasks, it shows both devices have the "online" checkbox as checked, but grayed out. No matter what I do (pause, disable and re-enable, etc.) they remain grayed out.
Recently we had some problems with the DC (where the Backup Exec is hosted), and it was rebooted a few times. Could this be the problem? Any help anyone could offer would be great. Thanks in advance!
