Create snapshots and snapshot objects

You create snapshots manually or by scheduling automatic collection of snapshots. Start by selecting the base volume or snapshot consistency group to be copied. Next, you add or adjust storage as needed. You can also create snapshot volumes to access the data in a snapshot image.

Create snapshot image
You can manually create a snapshot image from a base volume or snapshot consistency group. This is also called an instant snapshot or instant image .
Schedule snapshot images
You create a snapshot schedule to enable recovery in case of a problem with the base volume and to perform scheduled backups. Snapshots of base volumes or snapshot consistency groups can be created on a daily, weekly, or monthly schedule, at any time of day.
Create snapshot consistency group
To ensure that you have consistent copies, you can create a set of multiple volumes called a snapshot consistency group. This group allows you to make snapshot images of all the volumes at the same time for consistency. Each volume that belongs to a snapshot consistency group is referred to as a member volume. When you add a volume to a snapshot consistency group, the system automatically creates a new snapshot group that corresponds to this member volume.
Create snapshot volume
You create a snapshot volume to provide host access to a snapshot image of a volume or snapshot consistency group. You can designate the snapshot volume as either read-only or read-write.
