Recovering a single File From tape RRS feed

  • Question

  • Hey Guys

    I have a System Center 2016 DPM Administrator console, with a connected Tape reader.  I'd now like to restore a single file from a few months ago from this tape were I did a fullbackup with all the necessary files. Unfortunately, when I'm trying to get this file from the Recovery-Menu", it only showed me the backup of this month and I can't go back any further. I also can't get the single file under the Management tab, because it only allowes me to copy the whole tape, which isn't ideal either.

    Is there any way to copy only one File from this specific tape?

    Thanks for your Help.

    Cheers

    Gabe

  • Hello Gabe!

    Yes you can restore for a File Protection.
    The minimum granularity for protection is a single folder, but you can restore single files from a valid recovery point.

    What is your retention period for your tapes?

    Also where are you attempting to recovery the file from?  If under the Recovery tab, when you expand out the protected servers data sources, when you double-click the D: drive that should expand out the folders and files under it.
    You should be able expand each sub folder until you get to the files / folder you want to recover, then right-click and choose recover.  You can then recover to original location or alternate location.


    Best regards,
    Leon

  • Hello Leon

    Thanks for your reply. We're running the full-backup monthly. Unfortunately, I also can't select anything under the Protected Data either:

    II also can't select Tape... what do I miss here?

  • Hmm, the tape data should be under the External DPM Tapes, so you cannot select anything under that?

    For example this one:

  • I can select files, but unfortunately only from this month, I can't select any recovery points that are more in the past...but I can see that the Backup job did run through in the Monitoring.

  • I believe you don't see older tape backups because of the tape catalog retention settings. By default the catalog (which holds an index of what is on tapes) will be pruned if the retention range expires.

    You can run a tape management report and see what tapes are due back or overdue.

  • Try this:

    Go to Protection and then select protection group and click on View Tapes, when you identify tape you need recatalog it.

  • What is your Tape Catalog Retention?

    1. In DPM Administrator Console, go to the Protection view and select a protection group.

    2. Click Specify tape catalog retention. To prune the catalog when the retention range expires, select Prune catalog when protection group retention range expires. To prune the catalog for a specific tape duration, select Prune catalog for tapes older than, and then select the tape duration that you want to use.

    Note: You can’t retain catalog data longer than the retention range for the protection group.

  • Did you try to upload a picture? I can't see it for some reason.

    Have you identified which tape(s) you need to restore from? You can check in Management > Libraries and check their status.

  • That's also an issue: I don't know which Tape i need to select, because their named differently in DPM than the Nametags we gave them...I selected the one with "June" written on it, but it's just a guess unfortunately...

    And this tape has the following stastus:

  • I would suggest you to have the Protection Group name in the "Tape Label" so it's easy to identify.

    Go to Protection and then select the Protection Group where the file you want to recover exists in, then click on View Tapes, once you identify the tape you need, you can recatalog it.

    See here on how to recatalog:
