Snapshot groups and consistency groups

The Snapshot Virtual Disk premium feature supports the following types of snapshot groups:

Snapshot groups — A snapshot group is a collection of point-in-time images of a single associated base virtual disk.
Consistency groups — A consistency group is a group of virtual disks that you can manage as a single entity. Operations performed on a consistency group are performed simultaneously on all virtual disks in the group.
