Creating a VMware Snapshot

Creating a VMware Snapshot

After a snapshot is created and activated for a VMware instance, a data duplicate group of the VMware instance is generated. Users can read and write this duplicate without changing the source data. The data security is enhanced.

Prerequisites

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

Context

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

Procedure

  1. Log in to DeviceManager.
  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.

  4. Set snapshot parameters.

    Table 7-9 describes related parameters.
