Duplicate Data Elephant in the Room?

Smartly managed data replication is an important element of many enterprises’ IT operations.  Good.  The problematic distant cousin to this is data duplication.  A sloppy, hard-to-avoid problem.  Data deduplication (DD) solves this problem by eliminating redundant data and reducing storage requirements—also known as "intelligent compression" or "single-instance storage". Data deduplication can reduce the amount of data stored on media considerably, as well as improve data protection and increase the speed of service. Historically DD was a feature of appliances such as VTLs and WAN optimizers. Fortunately for many companies that cannot or do not want to afford the costs of these appliances, DD is now being incorporated into backups applications. Some key, specific benefits of DD include: Companies can see benefits in lower storage space requirements that will save money on storage budgets. In terms of storage space alone, we’ve seen up to 90% disk space savings. The more efficient use of disk space also allows for longer disk retention periods, which provides better recovery time objectives (RTO) for a longer time and reduces the need for tape backups. Data deduplication also reduces the data that must be sent across a WAN for remote backups, replication, and disaster recovery. Reductions in power, space and cooling requirements are also a benefit of DD. Within the virtual environment the ability to deduplicate VMDK files is a big benefit. The major vendors have DD capabilities, including EMC, Symantec, IBM, CommVault, Quantum and the like.  Check it out.
