Odd Datasources with \\?\Volume in the name RRS feed

  • Question

  • Hello,

    Running DPM 2012, and am looking at the output of get-dpmdatasource command.  I see my expected list of sources but also in this list I see my DPM server name (Backup04) along with volume names that don't match anything I'm trying to protect.  Is this some legacy stuff from my old 2007 install (2007 -> 2010 -> 2012).

    Small snippet of the output is below. This list is WAY longer than it should be due to these odd entries...

  • Definitely not due to upgrades, just tried the same command on a fresh DPM 2012 install and I see the same thing.

    I think what those are relating to are the backup volumes that you're backing your data up to. DPM creates those volumes automatically and then backs your data up to them, but they're generally hidden (eg they don't get allocated a drive letter). If you go into computer management, disk management, you'll see them displayed there. Note, if you have a lot of backups then expect it to take a LONG time to load disk management and display all the volumes. If / when you have to access those volumes yourself, for instance to move them or do some maintenance tasks to them, you'd reference them using the volume ID you see listed.
