What provides the fastest restore while minimizing backup size from a recent full backup?

The fastest restore process while minimizing backup size typically comes from choosing a differential backup after a full backup has been created. A differential backup captures all changes made since the last full backup.

This method allows for a quicker restoration because, during the recovery process, you only need the last full backup and the most recent differential backup to restore the system to the last state captured. This two-part restoration is generally faster than needing multiple incremental backups, as you would with an incremental strategy, where every subsequent backup requires a restoration of all previous incremental backups in addition to the full backup. As a result, the overall size of the backup is also smaller compared to a continuous full backup, while still maintaining the necessary data integrity for a quick recovery.
