Terminology

• Dedupe backup: In this mode, deduplication is done on the client and then the deduplicated packets

are sent to the DR Series system.

• Passthrough backup: In this mode, deduplication is done on the DR Series system after data is

transferred from the client.

• Synthetic backup:

A synthetic backup is identical to a regular full backup in terms of data, but it is

created when data is collected from a previous, older full backup and assembled with subsequent

incremental backups.

• Virtual Synthetic Backup/Optimized synthetic Backup:

A synthetic backup that avoids the need to

move data across the network. The media server tells the storage server which full and incremental

images to use to create the synthetic image.
