In a recent "Ask the Expert" on covering ways to consolidate backups centrally, you refer to a software solution that is "One of the best that I am aware of comes in the form of an Open Systems snap vault solution. This solution offers the ability to back up data based on the changes in the data itself, not the complete data set." My question is, what solution are you referencing? In this model will the data still reside at the remote sites and only the changes be backed up to a central location?
Any additional information about the solution and product would be appreciated.

The product that I am referring to is from Network Appliance and it works in conjunction with NetApp filers, including the NearStore R200 to move the data from the hosts to the filer in an intelligent way. The data still resides physically at the remote site but is copied based on block-based changes to the centralized site. Click here for information on this solution.
I have yet to run into another technology offering that can do what this offering can and I have looked at a bunch from a variety of leading data protection companies.
