Accelerator for D-NAS
NetBackup accelerator provides faster full backups at the cost of incremental backups, eventually reducing the backup window for customers. With this solution, more data is protected in the specified backup window and less bandwidth consumption.
After an initial full backup that protects all data from the filer, NetBackup accelerator backs up only the changed data from the filer to the media server. The media server combines the changed data with any previous backup images to create a new full backup image. If a file or portion of a file is already in storage and has not been changed, the media server uses the copy in storage, rather than reading it from the filer to complete the backup image. The result is a faster NetBackup NDMP backup.
To configure Accelerator for D-NAS, select the check box that is found on the policy tab.
Here are some benefits of using accelerator with D-NAS:
Creates a compact backup stream that uses less network bandwidth between the filer and NetBackup servers.
Reduces the I/O and CPU overhead on the media server and backup host.
Independent of storage arrays. Works with all the supported NAS storage arrays.
