    I was wondering if it is possible to aux copy a previous backup from a specific date from tape to disk?

    Good Day JReynolds2791,

    The basic answer to your question is yes. As long as said backup job id is availabe you can create an aux copy operation to pull from that job ids copy level and point it to be copied to apmost any other media type you want ie another tape or a disk library location. Using the proper aux copy creation criteria and advanced options in that aux copy can help you to narrow down your copy to only what job ids you want to copy even if it is just 1 job to be copied.

    I had some data that had aged off disk that was still on tape.  My tape library was at my HA site,  I thought it needed to be restored to my primary site.  My VMware guy wasn't around because it was after hours so I wasn't wanting to worry about vmotioning it.  I was thinking about copying the tape back to disk and DASHing it back to the primary site.  Its a moot point though as I ended up restoring it to the ESX hosts at the HA site.

    Thanks, got it, yes you could do that, but its messy as you would need to promote and demote copies I'm sure you know this. 

     In case you have to do this in future, one suggestion is you could restore the job itself out of place (to a stand by machine, like a Media Agent drive), then back it up as a normal job into your Primary copy to be dashed over (one time job).  Just provide some details in the job description or flag it somehow so it stand out.
