De-Duplication Rumors Highlight Controversy

A spate of industry chatter surrounding data de-duplication is reflecting a growing controversy over the best methods for deploying the technology.

The importance of data de-duplication is growing, exemplified by the success of Data Domain's recent IPO and fresh funding for Diligent Technologies. At the same time, storage professionals are being exposed to a cacophony of sometimes conflicting information about suppliers and their methods.

The rumor mill's on full tilt, for instance, regarding the potential for big vendors like EMC or Sun to add to or supercede their de-duplication partners. The latest whispers say EMC may announce a close partnership with Data Domain, to add to or replace de-duplication from its Avamar acquisition. (For the record, EMC and Data Domain refuse to comment on rumor or speculation.)

One thing to emerge from the swirling gossip is that suppliers are engaged in a fierce battle for mindshare that's liable to confuse would-be customers. And at the heart of the debate is the argument that some methods for de-duplicating data are proving to be better and more scaleable than others.

How closely should users listen to the rumblings for and against? Should the latest religious wars over data de-duplication be factored into the list of things prospective de-dupe buyers need to consider up front?
