    DDBoost is just deduplication plugin that works with EMC Data Domain, whereas NetBackup Accelerator is not equivalent to DDBoost. Accelerator uses not only deduplication technology of MSDP or OST  but also other various technology like change tracking and synthetic backup, to improve backup performance.

    Can it be used on a NAS ?

    i presume you are talking about backup source, so impossible. As you know, Accelerator requires NetBackup client on source. NDMP can not work with Accelerator.

    BTW, about use for backup destination,  it is possible to use Accelerator with NAS that support OpenStorage(OST) and Optimized Sythetics with it. but not possible with standard NAS that does not support Optimized Synthetics.

In facts, instead of synthetizing a Full Backup from 1 Base Full + x Incrementals, each Accelerated Full job sends only the delta blocs/files from the client to the dedupe appliance.

  • Without clientside dedupe, only delta files will be sent to the media server (and dedupe takes place there)
  • With clientside dedupe, only delta blocs will be sent to the media server (double benefit of deduplication process)
