NEW YORK Continuous data protection (CDP) might be getting all of the buzz of information lifecycle management (ILM) in the storage sector these days, but Microsoft isn't ready to embrace the technology approach.

The company is fresh off the launch of its System Data Protection Manager, which sits atop that Windows Server platform and provides near CDP, backing up byte-level changes.

DPM continually logs changes, but replicates data at most only once per hour, leaving as much as an hour of data vulnerable to loss.

Microsoft Senior Vice President Bob Muglia said the way vendors have been portraying CDP -- the practice of backing up and recovering data to disk from any point in time -- is somewhat of a misnomer at this point.

''This moniker of CDP is somewhat of a misnomer at the moment, because nobody really provides the ability to restore from any point in time for files,'' Muglia told

''And it may not even make sense. The feedback we get from customers is that that's not really an interesting scenario. Customers say several times a day is the most they want to do restores, and we provide more than that.''

But he also said Microsoft could look to offer CDP vis-a-vis DPM in the future as the company builds out its storage offerings atop the Windows platform.
