Retention Period

Hi all!

Just want to ask if there's any possible way to recover our data which is already reached the retention last December 27?

The data stored in MSDP.

Thank you in advance!
  • No. Not possible. 
    But I guess you already know this as you can no longer see the backup info in BAR, right?

    When expiration date for disk image is reached, all catalog info is deleted, followed by disk cleanup on media server.

    Only if data has been duplicated to tape and the tape is not yet overwritten, you can import from tape.

    Just double-check that your retentions are in line with business recovery requirements.

    This might help:

    .

    NetBackup - if a backup is due to expire it will be expired, irrespective of whether it is full or incremental.

    BackupExec - preceding full and preceding incrementals will not actually be expired until the last incremental expires.

    Therefore - the way "capacity" is managed is different between the two products.

    .

    So, I suspect that... either the data that you recovered from BackupExec was on tape, or that got lucky and BackupExec was still hanging-on to the backup data even though ostensibly it had passed its sell-by date.

  • BackupExec - preceding full and preceding incrementals will not actually be expired until the last incremental expires.

     

    This makes so much sense - there is no real purpose in having incrementals once the full expires...

      Hi Ma'am, thanks for the feedback.

      Yes we don't see any data or backup in the BAR.

      Expiration Date is also a Retention right? So if the configured retention is already reached, then the backup automatically removed from the storage MSDP. So the tendency we can no longer retrieve the data?

      Thank you and best regards!

        Your understanding is correct, 
        When retention is reached, NBU will expire all catalog entries as well as remove disk images.
