synthetic backup

A feature of the Advanced Disk-based Backup Option that enables a full backup to be assembled, or synthesized, from a baseline and subsequent incremental backups.

A synthetic full backup is a backup assembled from a previous, traditional (non-synthesized) full backup, and subsequent differential backups or a cumulative incremental backup. A client can then use the synthesized backup to restore files and directories in the same way that a client restores from a traditional backup.
