Microsoft DPM Backing up to Tape Failing

Hello,

I have recently setup a new backup server and i'm running Data protection manager on it. Currently I have all my backup copies going to disk, I had just installed "Firestreamer" (virtual tape library) and did what I thought is correct, but im getting failures when I run tape backup. I am testing the tape backups with a protection group that is only monitoring a small SQL database.

The error that DPM states is:

"The back up to tape job failed for the following reason: (ID 3311)"

I've tried rescanning the inventory under management for the tapes but still no luck...

Has anyone had any experience with backing up to tape?

Thank you,
Artie

So, has this tape drive ever worked?

what server (brand and model)?
what OS?
What tape drive?
what tapes?
how is the tape drive connected?
What drivers installed?

Hi thanks for the reply, it did work on the older DPM server... So what i did for more troubleshooting was create a new recovery point for each database in the protection group. I then tested with a "short-term" backup to tape for each, this worked fine. After that was completed i ran the "short-term" to disk and "Long-term" tape and they all worked. I also adjusted the time of night these run against the other protection groups.

I do not have a Tape library server, this is a Virtual tape library... (Firestreamer). I am using a backup server with Windows 2012R2, DPM is the only software running on it, as well as firestreamer... Are you familiar with this?

By testing the backup to Tape only, it worked. I then knew it wasnt a tape problem, it was more a configuration with the protection group, etc.
