Thanks Kevin for some insight. Our DD will actually be in our datacenter where about 80% of our servers are now, and we already do replication SAN-SAN every 30 mins, so we wont be replicating the DD unit, but we will be adding more and more. My biggest concern was managing the Symantec BEX for the years to come . heh

The dedupe/compression varies significantly by data set. It also grows over time. Our VM backups using vRanger are getting close to 70x dedupe, and growing. Some of our visual databases only get about 10x. With two units, replication is simple, and comes post dedupe/compression. So saves bandwidth. One recommendation is not to buy via Dell. EMC support through Dell is not good from what I hear. I was at a EMC customer council 2 years ago, and that was the number 1 complaint. But then again, we haven't needed support on the DD yet. I do recommend purchasing installation assistance. Not that it is difficult, but the paradigm is a bit different.

We currently have 4 6TB EQL's and are running a 9TB/wk backup rotation. The owners have requested to have all data backed up and readily available for 7 years. Nothing on tape. I heard that NetApp is one of the leaders in the de-dupe space but no idea for certain. We are using Symantec BEX 2010 Enterprise currently, and Veeam enterprise for our VM's (which are not part of the 9tb data backups currently). It looks like we will basically be backing up to the unit until its full (Dell says 30:1 or so) and then purchase a new one and so on and so on until someone thinks they spent too much. Are there any other ideas out there? Thanks ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
