Restore of differential incremental backup

Please excuse my maybe a bit stupid / basic questions, but I'm just getting started with NetBackup and didn't find an answer to this in the documentation.

I'm doing a full backup of a volume first, then I modify some files (create new files, rename files, delete files) and do a differential incremental backup (level 1).

Later on I try to restore the data. I use bprestore and restore the whole volume. Bprestore is able to restore the modified and added files from the incremental backup, however it also restores the files that I deleted after the full backup.

Is there a way to not restore those files?

Thanks,
Jan

    Hi Jan,

    I believe that would be the collect True Image Restore Information policy attribute

    Thanks,
    Jocelyn

    Hm, interesting.

    But when I modify my policy I can't select "Collect true image restore information". It's greyed out.

    Doesn't this work with NDMP?

    True Image Restore (TIR) must be enabled in the NetBackup policy and backups need to run with TIR enabled prior to being able to do any TIR recoveries.

    Yes, but please look at what I wrote:

    I can't enable it in the policy. The field "Collect true image restore information" is greyed out in my backup policy.

    I'm using Policy Type NDMP. When I change it to "Standard" I can select that field, but not with Policy Type NDMP.

    If it can not be selected for the backups then it cannot be used.
