A block-level synthetic full backup is a synthesized backup, created from the most recent block-level full backup and subsequent incremental backups. A synthetic full backup does not actually transfer data from a client computer to the backup media. Therefore, it does not use any resources on the client computer.
By default, block-level synthetic full backups use a single data stream. You can configure multiple streams for block-level synthetic full backups.
Note
-
You cannot run a synthetic full backup job if no incremental or differential backups were run after the last full or synthetic full backup.
-
The system will run an automatic synthetic full backup job only if all of the following conditions are true:
-
The current application size is greater than or equal to 1 GB.
-
The sum of the sizes of the backup jobs in the current cycle is greater than or equal to 1 GB.
-
The sum of the sizes of the backup jobs in the current cycle is greater than the current application size by more than 50%.
