About accelerator support
NetBackup accelerator for Cloud object store increases the speed of backups. The increase in speed is made possible by change detection techniques on the backup host. The backup host uses the change detection techniques to determine the current state of Cloud object store's objects or blobs to identify the changes that occurred since the last backup. The backup host sends the changed data to the media server in a more efficient backup stream. The media server combines the changed data with the rest of the cloud object store data that is stored in previous backups. If a portion of an object or blob is already in storage and has not been changed, the media server uses the copy in storage rather than reading it from the client. Accelerator backup has the following advantages:
Reduces the I/O and CPU overhead on the client. The result is a faster backup and less load on the client.
Creates a compact backup stream that uses less network bandwidth between the backup host and media server.
Creates a backup image that contains all data that is needed for restore.
