Differential backup


This option will back up all the changed and new added data based on the last time full backup. So the image file of the differential backup just related to a full backup. If one of the differential backup image file has been damaged or lost, it will not affect others. Compared to incremental backup, differential backup would cost more time.

You can still directly start an differential backup for a backup image from the Backup and recovery page by clicking Backup --> Differential backup.
