The VTL company says its new products can deduplicate and store petabytes of data.Today Sepaton announced the S2100-ES2 Series 1000 VTL, which offers 1Tbyte disks and as many as 16 processing nodes. The company claims the appliance can back up and restore 34.5Tbytes of data per hour. It also claims 1.6pbytes of useable storage for each appliance. Pricing starts at $69,000 for 10Tbytes of useable storage.

The company also launched the 5.0 version of DeltaStor, its deduplication software. New to the 5.0 version is a GUI that lets administrators select specific applications to dedupe, such as Exchange or Office files. Sepaton charges $2,500 per useable Tbyte for a perpetual license.

Sepaton's dedupe process saves data to disk, then looks for duplicate bytes. This is known as post-processing. Other vendors deduplicate as data is being written to disk. Another option, typically used in branch and remote offices, looks for duplicates on the source machine, thereby avoiding sending extraneous copies of data across the WAN to the home site.

Data deduplication is a hot topic in the storage industry. At last month's EMC World show in Las Vegas, EMC announced 3D technology to deduplicate data on storage systems. This complements its Avamar backup technology that deduplicates data at the source.

For more on data dedupe technology, this article by InformationWeek's Howard Marks provides an excellent overview.
