System Manager organizes snapshot images into snapshot groups . Snapshot groups require no user action, but you can adjust reserved capacity on a snapshot group at any time. Additionally, you might be prompted to create reserved capacity when the following conditions are met:

  System Manager automatically creates a snapshot group. This creates reserved capacity for the base volume that is used to store subsequent snapshot images.

• Any time you create a snapshot schedule for a base volume,

  System Manager automatically creates a snapshot group.
