Hi,

I have installed DPM 2012, i have HP tape library. I want to take the backup of multiple servers data. So i want to know how to create multiple libraries?

HI,

You do not need to have or use multiple tape libraries to backup multiple DPM protected servers.   Just create a protection group for each protected server and assign the tape library to each protection group.  Then make dedicated tape co-location PGSET's one for each protection group.  That will basically segregate the tapes so each PG has it's own set of tapes.  If you want to co-locate servers on the same tape, then assign each PG to the same PGSET.   The choice is yours.
