Backing up Exchange Databases from HD Library to tape

**Update**

Talked with managment for input, and dont know if backing it up as data chuncks would be the best way for backing these back up to tape. They suggested the possibility of restoring it to a location and then to back it up again from said location. 

Would make allot more sense to do it this way. If this is the best solution is there a way to take how they are currently backed up as data chunks on the 3Par HD Library and back them up to tape with a conversion back to dag files without having to restore it to another location first?>

So with the Aux Copy , since the data has already been stored on the 3par HD library, i can run a aux copy on that to tape and it would back up as exchange dags (like i would normally see them written to tape) or would they show up as data chunks like what i see in the 3Par Library?

As long as the chunks align to the jobs themselves that you’d be Aux Copying, you’d have restorable jobs there.

The files in your screenshot look like our writing format, so I assume they align to the DAG jobs (and likely other jobs as well).

The Aux Copy handles copying the necessary files for each job (including hydrated if Deduplication was involved).

It’s a pretty solid (and simple) process to ensure you have an offsite copy of the jobs.
