snapGroups The names of several snapshot groups that will contain the snapshot image. Enter the names of the snapshot groups using these rules:
  • Enclose all of the names in parentheses.
  • Enclose each of the names in double quotation marks (" ").

A snapshot image is a logical point-in-time image of the contents of an associated base volume. The snapshot image is created instantly and records the state of the base volume at that moment. Every snapshot image is created in the context of exactly one snapshot group. A snapshot group is a sequence of snapshot images of the associated base volume. A snapshot group has one repository volume used to save all of the data from the snapshot images. The snapshot images in a snapshot group have a specific order. The specific order of the snapshot images enables you to manage the snapshot images, such as restoring a specific snapshot image to the base volume or deleting the snapshot images that you no longer need.

The result of creating a snapshot image of a consistency group is a snapshot image of every member volume of the consistency group.
