What Impact Will Deduplication Have on Backup Performance?

High performance is essential to large enterprises that need to move exponentially growing, massive data volumes to the safety of a backup environment within a finite backup window. Understanding the performance distinctions between each category of deduplication technology-particularly as they change over time-is essential for choosing the most appropriate one for the specific environment.
Only a few years ago, data deduplication was a separate feature made available as an option for enterprise storage systems, mostly in the backup and archiving sectors. Subsequently, it has found new uses in cloud gateways, pairing down unnecessary blocks of data before it even gets to an array or virtual tape library. Now, as it becomes a taken-for-granted pre-integrated feature of unified computing systems, added awareness about how this can be most efficiently used is needed. This presentation takes a fresh look at some questions storage or IT managers should ask their storage vendors. Sepaton CTO Jeff Tofano is eWEEK's resource for this information.
