DPM 2010 tape status RRS feed

  • Question

  • Hi,

    In DPM 2010, when a tape has the status 'offsite ready', are there only these 2 options?

    1. Manually mark tape as free?
    2. Do take the tape offsite, and replace it. 

    When the backed up data on a tape expires. Will DPM recognice that and overwrite the tape? Or do i also need to manually mark it as free?

  • Hi,

    If the Tapes are left alone, they will go through the following states.

    1) New tapes need to be identified as "free" tapes before DPM can use them.  Once seen as free, tape backup can write to them and then...

    2) Tapes will show as having DPM written tape labels after the first backup is written to the tape.  Assuming the tape is not filled, or contains an expired dataset, the tape should be able to be used until the tapewriterperiod is exceeded.

    3) Tapes that are filled, exceed the tapewriteperiod, or have an expired dataset on them will be marked as "offsite ready".  It can remain in the library or taken out and replaced with a new free or expired tape so new backups can run.

    4) After ALL datasets on a tape have expired, the tape will show expired.  New tape jobs can now re-use that tape by overwriting it without any intervention, however, FREE tapes take precedence over expired tapes for tape jobs.
