Use the same tape everyday - DPM RRS feed

  • Question

  • Hi Everyone

    I have daily backups running everyday with retention of 7 days, however sometimes the following week the DPM keeps asking for a free tape and fails. Normally I force free the tape and erase then run manual backup, but this is time consuming.

    The other problem is for remote sites, tapes dont change on a regular basis as that is out of our control.
    Before with NTbackup, we would just erase whatever tape is the drive and run a backup. ie whatever tape is in the drive, a backup will take place.

    Is this supported in DPM 2012 ?

    Thanks

  • Hi,

    DPM 2012 UR2 (KB 2706783) Vyou can add a registry key to allow the tapes to expire in time for the next weeks backup.

    Tapes are marked as reusable on the next day after the date of expiry as DPM runs a reclamation job only at midnight. If you want the tape to be reusable on the same date as it is expired, create the ExpireDatasetOnDayStart 32- bit DWORD, and set its value to 1 under the following registry key:

    HKEY_LOCAL_MACHINE\Software\Microsoft\Microsoft Data Protection Manager\Configuration\MediaManager
