How full incremental backup in DPM 2010 works RRS feed

  • Question

  • Hi,

    We have configured full incremental backup in DPM 2010.

    We have a stand-alone tape drive connected to the DPM server and are doing
    daily backups. We'd like to use different tapes for each day. Will each of
    these tapes contain a full backup or will only the first tape contain a full
    backup and the others just incremental backups?

    Will it require all tapes to restore the Data from incremental tape, OR will it require only full backup tape and one incremental tape?

    Thanks,

    Manzoor ahmed

    As per http://technet.microsoft.com/en-us/library/ff653493.aspx

    STANDALONE TAPE DRIVE
    =======================
    For standalone tape drives, all SHORT TERM backups are appended on a single tape and all LONG TERM backups are appended to a single tape (different from the short term tapes). As tapes fill up, DPM will raise an alert to add a new free tape.


    DPM will prompt for another free tape to continue backup. It will wait for 1 hour by default before failing the job. This prompting timeout can be configured by the registry entry "PromptingTimeOut" under "HKLM\Software\Microsoft\Microsoft Data Protection Manager\1.0\Prompting"

    PromptingTimeOut:REG_Dword:43200000 (dec) = 12hrs

    =-=-=Value is in milliseconds=-=-=
    3600000 = 1 hour
    43200000 = 12 hours
    86400000 = 24 hours
    129600000 = 36 hours
    172800000 = 48 hours

    Depending on what fle (and date) you choose to restore will determine what tape is required for the restore.  You can view tape list under the recovery tab to see what tape is required for that file to be restored.

  • Hi,

    tape backup only does full backup and no incremental.
