You create a snapshot consistency group when you want to make sure snapshot images are taken on multiple volumes at the same time. For example, a database made up of multiple volumes that need to stay consistent for recovery purposes would require a snapshot consistency group to collect coordinated snapshots of all volumes and use them to restore the entire database.
The volumes included in a snapshot consistency group are called member volumes.
Create a snapshot image of a snapshot consistency group to get simultaneous images of the member volumes.
Create a schedule for the snapshot consistency group to automatically capture periodic simultaneous images of the member volumes.
Create a host-accessible snapshot volume of a snapshot consistency group image.
Perform a rollback operation for a snapshot consistency group.
