We started having a lot of backup failures with BE 12. The backup media is an external Tandberd RDX, and it is running the latest firmware. There is an RDX utility that shows the drive is healthy. We upgraded to BE 15, and the problems are persisting.
There are two problems:
1) One problem is that either very shortly after a job starts or well into it, a media request alert pops up. The job stops progressing, but I can go into Windows Explorer and see the disk that Backup Exec wants to eject and browse through the folders. As soon as I acknowledge the alert, the disk ejects, and the job fails. This has started happening daily, so we haven't had a full set of good backups in a week. We are backing up 3 systems, and last night it failed on the first one, but the previous night it failed on the 3 system. The Event Viewer has Event ID 58061 and "Backup Exec Alert: Media Insert
(Server: "SERVER1") (Job: "HR2 Backup-Full") Please insert a different disk cartridge that has free space or expired backup sets." These disks are 1 TB, and about 1/3 of them are free space.
2) The other problem is that the disk goes off-line. I can force it back on-line, and the job finishes up OK.
Can anyone provide me with some thoughts as to what I can try?
How big is the size of your backup set?
Have you tried leaving the disk in the device for more than 4 hours before the start of the backup jobs? This is to allow DLM to reclaim any expired backup sets.
