Configuring a NetBackup policy for Hitachi_ShadowImage or Hitachi_CopyOnWrite
For general help setting up a NetBackup policy in the NetBackup Administration Console, refer to the NetBackup Administrator's Guide, Volume I.
The following procedure focuses on the Hitachi_ShadowImage and Hitachi_CopyOnWrite methods and their parameters.
The term "clone LUNs," as used in this procedure, refers to the Hitachi_ShadowImage method. For the Hitachi_CopyOnWrite method, the term "clone LUNs" can be replaced with "snapshot LUNs."
To configure a NetBackup policy for Hitachi_ShadowImage or Hitachi_CopyOnWrite
- In the NetBackup Administration Console, click the Perform snapshot backups box on the policy Attributes tab.
- Click the Options option to display the Snapshot Options dialog box.
- In the Snapshot method pull-down list, select Hitachi_ShadowImage or Hitachi_CopyOnWrite.
- In the Snapshot Resources pane, click Add.
NetBackup uses the information in the Snapshot Resources pane to correctly rotate through the designated LUNs when performing a ShadowImage (or CopyOnWrite) backup. After all clone LUNs have been used in a backup, NetBackup automatically determines which clone is the oldest. NetBackup expires the oldest clone so that it can be reused for the current backup. If that clone represents the only backup image copy, NetBackup also expires the backup image associated with the clone.
Note that the policy's Backup Selections list must specify one or more source LUNs for which snapshots are created for the backup. For each source LUN in the policy Backup Selections list, you must supply a serial number and unique IDs.
If the snapshot resources specified in the Snapshot Resources pane do not match with the LUN IDs specified through the backup selection entries then the NetBackup Hitachi storage array plug-in will discover the available target device and use it for snapshot.
See Obtaining the Hitachi array serial number and the unique device identifiers.
- In the Add Snapshot Resource dialog box, enter the array's serial number in the Array Serial # field.
- Enter the unique ID for the source LUN in the Source Device field.
The ID must be entered without leading zeroes. For example, if the LUN ID is 0110, enter 110 in the Source Device field.
- Enter the unique IDs for the clone LUNs (for Hitachi_ShadowImage method) or the snapshot LUNs (for Hitachi_CopyOnWrite) in the Snapshot Device(s) field. To enter multiple IDs, place a semicolon between them.
The ID must be without leading zeroes. For example, if the LUN ID is 0111, enter 111 in the Snapshot Device(s) field.
Note the following:
The LUNs must be unmasked to the client (or alternate client) before you start a backup.
For Instant Recovery backups, the Snapshot Device(s) entries determine where and in what order the snapshots are retained.
