NEC enhances Hydrastor with universal dedupe transfer, OST Accelerator

NEC Corp. of America has enhanced its Hydrastor scale-out backup and archive storage platform with a Universal Dedupe Transfer and added an Open Storage Technology (OST) Accelerator for Veritas NetBackup. The new features in HydraAstor 4.4 are aimed at cloud service providers.

The company’s Universal Dedupe Transfer capability supports Linux while Windows and Solaris support are on the road map. Dedupe Universal Transfer pre-processes data stream on the media server and allows customers to do high-speed full backups from a remote location.

It’s built on NEC’s Universal Express I/O, which was introduced in the previous software upgrade, and includes in-flight compression and encryption. The capabilities can be deployed together to maximize bandwidth and get higher performance.

“This opens the door to extend remote backups. Rather than put separate systems in each location,” said Gideon Senderov, NEC’s director of product management and technical marketing. “Just place dedupe transfer software on the source side. Before if someone wanted remote backup, they would have a full system in remote locations and replicate data. This eliminates the need for that. It makes it possible to do full backups over the wire. Each hybrid node gets up to 40 Terabytes an hour.”

NEC’s Universal Dedupe Transfer also does not require application-specific integration. The capability is built on the Universal Express I/O function that NEC introduced in the previous upgrade.

NEC also introduced an OST Accelerator for NetBackup for automated and speedier backups. This capability offloads the synthetic full back up process from the media server to Hydrastor nodes. It also automates the synthesis of the subsequent full backup as the new incremental backup is received. Users can eliminate weekly full backups from the job schedule and maintain an up-to-data backup image with only incremental backups.

“The full backups and incrementals are all read into the media server so it doesn’t have to collect from all the clients,” Senderov said. “So the media server creates new files and writes them to the storage system. With incrementals, it automates the synthetic changes into full backups at the storage array.

“The incrementals are done to the array and the synthetics constantly create a new full. We optimized metadata pointers and eliminated a lot of reads and writes so there is a high GBs performance improvement.”

NEC also upgrated its HydraStor monitoring management tool, adding a command line interface that aggregates deduplicaton and compression statistics per backup job.
