I would just expand that Kurt can still meet his 5 year retention policy. It will just be there in one 'blob' of bits. The original copy and then all the 'incremental' changes. It will, in my opinion work much better in that scenario. No thinking about what tape is at what storage site. Just hit the spiffy calendar in DPM and pick the document and pull it back.
So if offsite storage is needed, set up a second one and replicate it off site/cloud. -----Original Message----- From: Michael B.

After that, only changed blocks are backed up. That's on disk. Generally, I see 50-60 generations of files being kept by clients. You can do a tape dump of the full image but that's not really the way DPM is designed to work. It takes a slightly different perspective than traditional backup products. -----Original Message----- From: Kurt Buff [mailto:[email protected]] Sent: Thursday, April 19, 2012 3:08 PM To: NT System Admin Issues Subject: Re: MS DPM Opinions To further this conversation - what multiple of disk space does DPM have available vs. the disk consumed in production, and what kind of history do you keep? We're contemplating moving from Ultrabac and a tape robot to DPM, and are currently doing a standard Grandparent/Parent/Child tape rotation with a 5 year retention for the archive.
