Cannot Restore External Tape with DPM2010 - Unrecognized and unreadable

I am trying to restore some file server data that was written on an LTO3 tape a couple of years ago. I have been in my current role for about a year; but am fairly certain it was Backup Exec 12.5 that wrote this tape. The old Backup Exec server failed a while back and has been removed. Same with the LTO3 drive that created the tape.

Our new backup server is Microsoft DPM 2010. It uses an LTO4 library that is dedicated to DPM. When i try to view the tape and inventory it; it still shows as unrecognized. The LTO4 drive can see the LTO3 tape; but DPM is not recognizing any data on it.

Is there a tool or program I can load onto my DPM2010 tape server (Server 2008 R2 x64) that can view tapes and potentially restore the data? Do I maybe need to load BackupExec onto this system?

- i'd hate to install Backup Exec on this server and have it screw up our current backup program/configuration with DPM 2010.

Any other tips/tricks to help with this issue would be greatly appreciated.

Thank you

According to several places on the web Backupexec uses "Microsoft Tape Format" on its tapes

OK - DPM is dedicate to the tape library; so I think I will find another LTO4 drive and attach it to a different server and use NTbackup. Correct?

So it appears!

I was hoping there would be a Windows program that I could load that would read various types of tapes; just like an external HD. I'm assuming I need to get my head out of the clouds?
The suggestion to get another LTO4 drive on a different server is your best option, but you must likely have to install Backup Exec on it. NTBackup may not play ball when trying to restore - despite Backup Exec being MTF format. After all, DPM uses MTF format as well.
You can get a Backup Exec trail from that you should be able to restore from if you no longer have BE.
