Virtual Tape and DPM

ICTHelpdesk asked
Last Modified: 2012-05-09
I've started using DPM 2010 for DRing to another site. I've bought a cheapish Promise 16 disk ISCSI controller to hold the data and I'm about to buy 16 2T disks The server has 4.6T dedicated to DPM which is completely full with only 1 days backup.

The question is should I buy virtual tape software or just raid 5 all the disks?
