Modifying a Snapshot

Prerequisites

Scheduled snapshots cannot be modified.

Procedure

1. Choose Data Protection > Protection Entity > Namespace > Snapshot.
2. Select a desired account from the Account drop-down list in the upper left corner.
3. Select a desired namespace in the namespace list on the left. In the function pane on the right, click More on the right of a desired snapshot and select Modify.

   The Modify Snapshot page is displayed.

4. Modify the snapshot name.
   

   • The name contains 1 to 255 characters.
   • The name can contain only letters, digits, and underscores (_) and must start with a letter.

5. Change it to a secure snapshot.
   

   • Initialize the WORM clock before enabling the secure snapshot function.
   • After the snapshot is changed to a secure snapshot, it cannot be changed back to a common snapshot.

   The secure snapshot function ensures that the snapshot enters the protection state according to the settings after being created. During the protection period, the snapshot cannot be deleted but can be read for multiple times.

   Table 1 describes related parameters.
