The synthetic backup feature eliminates the need to perform recurring full backups for supported remote resources. The synthetic backup is assembled from a full backup (called a baseline) and subsequent incremental backups.
The resulting synthetic backup then becomes the new baseline. Only incremental backups are required until the next synthetic backup is created. The synthetic backup is as current as the last incremental backup that it contains.
The components of a synthetic backup are as follows:
The baseline backup is the first full backup to run that is associated with the synthetic backup. The full baseline backup runs one time only, and backs up all of the files on the selected computer when it runs.
The synthetic backup process combines the data from the baseline backup and the incremental backups to form a synthesized full backup of the selected computer. This synthesized full backup becomes a new baseline backup, which is combined with subsequent incremental backup sets to form a new synthesized full backup.
True image restore is automatically enabled for synthetic backups. True image restore lets you restore directories as they existed at the time of the synthetic backup. Files that were deleted before the time of the synthetic backup are not restored. In true image restore, only the correct versions of files are restored from the appropriate synthetic full or incremental backups that contain them.
