Database data is growing 25 percent yearly, with unstructured data related to online collaboration, Web 2.0 applications, messaging systems and other digital avenues increasing at 50 to 75 percent, according to The Enterprise Strategy Group. Storing all this data can strain IT architectures, a stress made worse by unnecessary duplication of data. Consider, for instance, that simply updating a customer address often prompts the system to resave the entire customer file even though nothing else in the file has changed.
Tackling data duplication by eliminating unnecessary backups reduces storage footprints and cuts the power and cost needed to maintain data center facilities. According to the ESG report, so-called data deduplication products identify and eliminate redundant data and thus "cut data protection capital and operation expenses, facilitate consolidation of distributed backup operation, and slash server virtualization-related storage costs. Data deduplication offerings should, therefore, be on every CIO's project short list."
