DeltaStor software is a next-generation data deduplication application for the SEPATON S2100-ES2 virtual tape library that enables enterprises to store more data online at a cost that is comparable to physical tape systems. By changing the economics of data storage, DeltaStor software allows enterprises to reduce risk, handle exponential data growth, cut backup times, and significantly lengthens online retention periods for faster restores. DeltaStor software draws on SEPATON's unique ContentAware™ architecture, which contains built-in intelligence about file content and the backup data relationships of leading backup applications, to deliver unparalleled speed, simplicity, scalability, and data integrity. This whitepaper will discuss the technology fundamentals of the product and how it can be used to save money, time and increase efficiency of backup and restore operations.
