Creating a VMware Snapshot

Prerequisites

• At least one VMware instance has been created on the storage system.
• The HyperSnap license is valid.

Context

• A snapshot created for a VMware instance that does not use shared folders is actually a snapshot group. When you create a snapshot for a VMware instance, you actually create a snapshot for each LUN contained in the instance. You can choose Data Protection > Snapshot to view the snapshot of each LUN contained in a VMware instance.
• A snapshot created for a VMware instance that uses shared folders is actually a snapshot of a file system.

Procedure

2. Choose Provisioning > Application > VMware.
3. Select the VMware instance for which you want to create a snapshot and click Create Snapshot.

   The Create Snapshot dialog box is displayed.
