Full Backup Jobs & Tapes RRS feed

  • Question

  • Hello,

    What I would like
    Store many full backups of the DC onto one tape.  Any suggestions, links, or tips on how to allow this?

    • This way I can store a years worth of DC backups onto only a tape.  Well okay, I wouldn't be that cheap.  But you get the idea.  Then if my domain is compromised I can revert back to hopefully a safe state.

    Scenario
    DPM backs up a domain controller system state short term to disk (daily), then long term to tape (once weekly).  Because the tape backup is a full backup, DPM requires a new tape each week.  This is only a few GB's for a 1.5TB tape.

    We dont store these tapes offsite (the DCs are off site)

    So I am backing up about 20GB of data on one tape every week, kind of a waste in this scenario, yeah?

  • Hi,

    This is by design of DPM I believe.

    Long-Term Tape Protection
    A tape will be allocated for each full backup job. The reason long-term full tape backups are on separate tapes is because they are meant to be stored offline, and possibly offsite. So each long-term backup recovery point created will always be on a new tape.

    As far as I know tape protection is something that people are trying to move on from, since disk prices have gone down ever since and you can get NAS for quite a reasonable price.

    I myself used long-term protection on NL disks in our disk system.

    Hope this helps!

    Kind regards,
    Leon
