Source Side De-duplication: Page 2 of 2

Source-side de-duplication seems to be most often deployed in either remote office backup configurations, where WAN bandwidth is constrained, or VMware Inc. (NYSE: VMW) environments via integration with VMware Consolidated Backup. EMC Corp. (NYSE: EMC)'s Avamar, for example, does a good job of integrating with VMware's VCB, which is an environment that is almost tailor-made for data de-duplication.

Source-side data de-duplication is often confused with or compared to Block Level Incremental Backup solutions, which we will talk about next.

George Crump is founder of Storage Switzerland, which provides strategic consulting and analysis to storage users, suppliers, and integrators. Prior to Storage Switzerland, he was CTO at one of the nation's largest integrators. Previous installments of his discussion on data de-duplication can be found here.
