Another plus is that snapshots allow much more frequent protection than backup.

In read performance, SSD is 5x Faster than HDD, while NVMe is 5x Faster than SSD.

The main difference between snapshot backup and backup is that the latter required installation of backup agent and backup storage as the destination to store the backup.
