Scratch tapes = DRMedia

    Hi all, I know this may sound stupid but I just want to clarify. Are Scratch tapes the same as DRM tapes? I thought Scratch tapes were new tapes with no data on them and DRM tapes had Media on them!

    Just like a scratch disk, or a scratch pad, it's for temporary storage only. http://en.wikipedia.org/wiki/Scratch_tape

    I know what they are but are they the same thing?

    Honestly, I've never heard of media referred to as DRM media (though a google suggests it relates to IBM Tivoli, which I have no experience of. is that what you're using?).

    If so, I found this: http://www.backupcentral.com/components/com_mambowiki/index.php/Disaster_Recovery_Manager_(DRM) which suggests that they're not the same. DRM media looks to be used for Bare Metal Recovery.

    The term DRM media might be specific to whatever app you're using, so I could be looking in the wrong place!

    Yes we use IBM Tivoli. All the senior admins seem to say they are the same thing as scratch tapes but to me that doesn't really make sense. Thanks for the link i'll take a look.

    Just clicked on the link but it must be gone. "no text on this page" or something. thanks anyway though.

    From a Tivoli perspective for bare metal restore I would have thought that the DRM media is OS Image (mksysb's etc.), tsm database backup and your offsite backup tapes. I've always thought of scratch tapes as new tapes introduced. Once assigned to a copy_tape pool they are still scratch till data is backed up to them. :confused:

    scratch generally means it's not been used or that it is available for use

    In backup exec you can assign media to the scratch media pool so that any job can then use it irrespective of the previous pool's media retention time
