  • When DPM performs a tape backup it writes information about the data written to the tape in the DPM database.  DPM needs to know whats on the tape so it can show you the recovery points in the Recover tab.

    DPM automatically prunes this information from the database once the retention range expires and to stop the database size growing to large.


    As Martin said - you need to recatalog the tape.  DPM will read the tape to determine whats on it and then stores that information back in the DPM database. 

    Goto the Management tab -> Libraries -> Select the tape and use the "Recatalog imported tape" option

  • MNYAsh,

    Another possible expaination is you are looking for the recovery point on tape at the wrogn time.   If you schedule a LT tape backup to occur at 1:00AM, but the last disk based recovery point was at 8:00PM the previous day, the tape based recovery point will be at 8:00PM, not the time the tape backup ran at 1:00AM.  This is because the LT tape backup mounts the last disk based snaphot and copies that to tape.   From a recovery point of view, the data on tape is not newer than the disk bases RP, so both the disk and tape RP will be under the 8:00PM RP on the day before.
