Having good backup, retention and e-discovery strategies helps TEP know how much storage it needs. Once an enterprise has these rules and mechanisms worked out, it can begin investigating products, says Ovum analyst Tim Stammers.
Stammers suggests a strategy involving data deduplication, which takes common elements of documents that have many copies and saves them once to cut the amount of storage capacity you need. Storing data in the cloud, through services offered by such vendors as Amazon.com and Nirvanix, may also be more economical because you won't need in-house staff to manage the systems.
