CDP Gets SNIA'd

Not sure what CDP is? You're about to have your consciousness raised.

A group of 14 vendors has launched a new Continuous Data Protection (CDP) special interest group within the Storage Networking Industry Association (SNIA), signaling an increase in attention for this technology trend (see SNIA Establishes CDP SIG).

CDP refers to software that combines data backup, replication, snapshotting, and other techiques. Typically, it creates one backup followed by efficient replication of any change that is made to the data. Since the updates are ongoing, CDP allows for rapid data restoral in case of an outage, and it also makes it possible to go back to a specific point in the life of the data.

The new forum seems to be as much about marketing this emerging technique as it is about setting standards for its use. Interestingly, some of the founding members of the SNIA CIG include biggies who haven't yet unveiled CDP products, such as EMC Corp. (NYSE: EMC) and Veritas Software Corp. (Nasdaq: VRTS).

"At the moment, we don't have a CDP product," says EMC spokesman Todd Cadley. But joining the SNIA SIG indicates EMC is "obviously moving toward a strategy" that includes CDP. A product will come in three to four months, he says.
