About the NetBackup Accelerator for virtual machines
NetBackup Accelerator reduces the backup time for Hyper-V backups. NetBackup uses Hyper-V resilient change tracking (RCT) to identify the changes that were made within a virtual machine. Only the changed data blocks are sent to the NetBackup media server, to significantly reduce the I/O and backup time. The media server combines the new data with previous backup data and produces a traditional full NetBackup image that includes the complete virtual machine files.
Accelerator is most appropriate for virtual machine data that does not experience a high rate of change.
Accelerator has the following benefits:
Performs the full backups faster than traditional backup. Creates a compact backup stream that uses less network bandwidth between the backup host and the server.
Accelerator sends only changed data blocks for the backup. NetBackup then creates a full traditional NetBackup image that includes the changed block data.
If the Hyper-V tab is enabled, you can restore individual files from the backup (full or incremental).option on the policy
Reduces the I/O on the backup host.
Reduces the CPU load on the backup host.
