DPM 2012 SP 1 – Tape import and recataloging

Within the last days I was switching from Data Protection Manager 2012 beta SP1 to the final Build which is available for TechNet and Volume Licensing customers at least since the 1st of January.

And I thought moving the Tapes and the MSL Library from one Server to another without the SQL Database is a kind of disaster recovery and likely an option to proof the concept of long term backups via tape. 😉

If the DPM Server is destroyed you will also lose the knowledge where and what files are located on the tapes and/or disks.
Keep in mind the DPM brain is stored in the SQL Database with reports, client server configurations and all this stuff.
Although you don’t have any of this you can simply get your data back with importing end recataloging the tapes.

What you need is another running DPM Server and, sure, a tape drive that’ll read your tapes. 😉

First step – you start inventorying the whole library or if you use a single drive with the inventory button on the left top side on the ribbons.
After and during the inventory you will see the tag/description (Imported) in front of you tapes.


But you also want to know what exactly is stored on the tape?
If you try to take a look and hit the “View tape contents” line in the middle …

… the following info box appears.

Sure you want to do that.
Note: Attentive observers would see there was a shorter way and hitting the line “Recataloging the tape” is quicker.

Anyway… the tapes will be “marked for recatalog and waiting for drive” now.

The tape drive is reading the tape and …

… after finishing you get more information. You see a date and what is stored (and maybe when it is expired or will be).
That should suffice for a first look.

Switch to the recovery and take a look. You’ll see “External DPM Tapes”.
You can browse through the backed up data and dig deeper if you need. 😉

If the tape is still in the library/drive DPM will read more data if needed and you’ll get a message.
“Please wait while DPM reads tapes …”

If the DPM could read enough data from the tapes you can look for whatever you’re looking for and recover your data.

Note: If you don’t need a deeper look and it’s not necessary to search for specific files you can simply recover the whole volumes/system the usual way. 😉
