DPM 2012 - Single tape drive - Daily onsite, monthly offsite RRS feed

  • Question

  • I am trying to configure DPM 2012 for the following:

    • Daily backups to disk (onsite)
    • Monthly backups to tape (to be sent offsite) for retention for 6 months

    I have a single tape drive not a library, and assumed I could do this by setting a short term goal of every 24 hours, and a long term goal of 1 month, leading DPM to backup to disk every day then once a month copy that backup to tape.

    However, no matter how I jiggle these settings around, I can't get rid of the line "Please ensure that there are a minimum of two tape drives or two tape libraries for copy backups" from the "select library and tape details" setting tab.

    I'm not trying to get DPM to create a copy from tape, should I ignore this warning or have I missed something in the way I'm trying to configure things?

    Thanks in advance for any help.

  • Hi,

    Using your configuration, you do not need more than one tape drive.  DPM will effectively make the long term backup from the last disk based recovery point.  You can make a custom job filter to view scheduled tape backups for the next 7 days and confirm the job type is "tape backup" and not "dataset copy".

  • Thanks for your quick answer Mike. I'll leave things as they are in that case, the "Please ensure that there are a minimum of two tape drives or two tape libraries for copy backups" message confused me, but I assume this is always displayed even if 2 drives aren't required for the job.
