Optimized synthetic backups for deduplication

NetBackup environments that use the NetBackup Data Protection Optimization Option license can benefit from the optimized synthetic backup method.

This method constructs the synthetic image by using calls from the backup server to the storage server. The backup server tells the storage server which full and incremental images to use to create the synthetic backup. Then, the storage server constructs (or synthesizes) the synthetic image directly on the storage server, reducing network traffic.
