One of the big reasons disk-based solutions have been able to have a positive impact on operations and budgets is the introduction and use of data deduplication technology. In short, systems utilizing data deduplication only save unique data - all redundancy at the file, byte, or block level (depending on the solution) is removed. Since there is so much duplicate data in secondary storage environments, users are able to save much more logical capacity in a single physical device. This has allowed disk-based backup systems to meet or beat the acquisition and operating expenses - indeed, the total cost - of tape. Read on to learn more about the advantages associated with a disk-based backup system.
