DPM 2012 R2 Backup to Tape Long Term - how do I turn off the copy RRS feed

  • Question

  • I use DPM 2012 R2, and want to remove the '1 copy' from my long term backup to tape selections.

    I don't need the copy, so therefore it is superfluous aside from the fact that it fails every time.

  • Hi,

    1 copy means a single copy, IE there is no such thing of having zero copies.

    What is the reason for the backup job to fail ?

    Do you have multiple backup goals configured but only have a single tape drive ?

    DPM does tape copies of daily tapes to make the weekly tape, and copies of the weekly tape to make the monthly tapes.  You should see a warning when you go throught the PG Wizard if you only have a single tape drive.

    When you go throught the PG Wizard for a PG that has two or more long-term recovery goals specified, and you only have a single tape drive, on the "Specifylibrary and tape details" page, you should see a yellow ! with "Please ensure that there are a minimum of two tape drives or two tape libraries for copy backups to succeed.

  • Currently I have short term, and long term (3 options for weekly, monthly and yearly) setup, all of the options are set to go off at the same time, so I don't duplicate backups and waste tapes. Also, the tape library only has 1 tape drive setup in it.


    The backup itself appears to go through on any weekday, on the Full backup long term days, the initial backup to tape works, but an error stating 'data copy fails' occurs after the successfull backup.  so I will assume by the description you put up that it is attempting to do the secondary and tertiary goals of the long term, and therefore should be expected.

  • Ack, I fail on reading comprehension.

    Ok, if I now read this right, I need 2 tape drives to use DPM for long term to tape storage... considering I use Tape as my short term as well.

    *hair pull*

    I was under the impression, as I completely ignored those warning messages, that the long term backups made thier own separate backups on the day that they were scheduled for.

    Add to this, I actually had a Monthly backup Succeed where all my other weekly long term backups have failed, which threw me for a few.

    Is there any functionality change with patches, fix with scripts or workarounds for this issue?

  • Hi,

    I agree the design is not optimal for single drive configurations.  There is no way around the requirement so the longer recovery goals tape copy jobs can run.

  • I want to like this product, but the further into getting to know it, the less and less I can actually use it due to its narrowly defined parameters.  My Boss put it succinctly, "the more we have to use workarounds, and registry keys and change our own procedure to accommodate a software that is spose to work for us, the less we need it"
