  • Persistent recovery job locks tape drive
    Posted: 03-12-2014, 4:59 AM

    The data archiving "Persistent Recovery" job, once started, runs effectively for ever.

    Actually it will stop after 24 hours by default, but this is configurable only by doing a registry hack on the CLIENT machines (correct me if I'm wrong here) which is pretty unhelpful.

    However, if the persistent recovery job needs to get something from a tape, as sometimes happens, it loads the tape into the drive and then keeps a lock on the drive indefinitely - unless I kill the Persistent Recovery job, which is a manual intervention I don't want to have to make on a regular basis.

    The result is that my Aux Copy jobs, trying to use the same tape drive, get pre-empted and never restart. Clearly I don't want the Persistent Recovery job to wait for the Aux Copy to finish, since that might take hours or even days, and a user is waiting for the recovery; so fiddling with job priorities is not going to fix this.

    Is there a way to get the Persistent Recovery job to gracefully surrender the tape drive once it's finished using it, so that my normal backups can continue?

    Update - I have discovered that this is not the default behaviour. In fact the Persistent Recovery job DOES surrender the tape drive once it has finished using it. I was being impatient.

    But I can't delete the post above due to a program error on the web site.

    Moderators? Can you remove it? Thanks.
