You create a snapshot consistency group when you want to make sure snapshot images are taken on multiple volumes at the same time.

Why would I create a snapshot consistency group?

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.

You can perform the following snapshot operations on a snapshot consistency group:

  • 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.
