A block-level synthetic full backup is a synthesized backup that is created from the most recent block-level full backup and the subsequent log only backups. A synthetic full backup does not transfer data from a client computer to the backup media. Therefore, it does not use any resources on the client computer. You can back up the synthetic full data on a storage policy with a single drive or data path.
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.
Best practice: Run a log only backup either before or after a synthetic full backup.
-
When you run a log only backup before a synthetic full backup, any new or recently changed data is included in the synthetic full backup.
-
When you run a log only backup after a synthetic full backup, any new or recently changed data that was not included in the synthetic full is included in a log-only backup.
Procedure
-
From the CommCell Browser, expand Client Computers > Client > PostgreSQL > Instance > FSBasedBackupSet.
-
Right-click the subclient that you configured for performing a block-level backup, and then click Backup.
The Backup Options dialog box is displayed.
-
Select Synthetic Full as the backup type.
-
In the Job Initiation section, specify whether you want to run the backup job immediately or to schedule it.
-
Click OK.
Result
The Job Controller displays the synthetic full backup job as Synthetic Full.
