Configuring snapshots for LUNs
These are the general steps for applying specific snapshot configurations to LUNs through Core.
1. Select the LUN for the snapshot and access the snapshot settings. You can access the snapshot settings for a specific LUN by choosing Configure > Manage: LUNs. Select the desired LUN to display controls that include the Snapshots tab. The Snapshots tab itself has three tabs: Configuration, Scheduler, and History.
2. Apply a snapshot schedule policy to the current LUN. The controls in the Scheduler tab enable you to apply a previously configured policy to the current LUN. You can create a new schedule directly in this pane.
3. Specify the storage array where the LUN resides. The controls in the Configuration tab enable you to specify the storage array where the current LUN resides and to apply a static name that is prepended to the names of snapshots.
4. Specify the client type. The controls in the Configuration tab enable you to specify the client type. To configure application-consistent snapshots and a proxy backup, you must set this value to Windows or VMware.
5. Enable and configure application-consistent snapshots. The controls in the Configuration tab enable you to enable and configure application-consistent snapshots. The settings vary depending on which client type is selected.
