After EMC Corp. bought deduper Avamar Technologies, and Hitachi Data Systems Inc. execs said the company will continue to rebrand and resell deduping software from Diligent Technology Corp.
The big difference is that Avamar uses agent software on each server that dedupe data before it's sent to central storage. Diligent dedupes in a central repository. Avamar says that's an inefficient use of bandwidth; HDS likes the ability to keep an index of all the data in central memory for quicker response during backup and recovery.
Analysts said the products are apples and oranges, but that EMC's acquisition might set other vendors off to buy dedupers of their own.
