Configuring a NetBackup policy for IBM_DiskStorage_FlashCopy
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 IBM_DiskStorage_FlashCopy method and its parameters.
To configure a NetBackup policy for IBM_DiskStorage_FlashCopy
- 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 IBM_DiskStorage_FlashCopy.
- If needed, set Wait for flashcopy operation to complete to 1.
By default (0), the backup does not wait for the FlashCopy operation to complete. If the backup begins before the FlashCopy operation completes, database performance on the client (such as Oracle) may be affected until the FlashCopy is complete. A setting of 1 means that NetBackup waits for the FlashCopy to complete before the backup begins, to avoid any performance issues on the client.
Note that a setting of 1 may cause the backup elapsed time to increase significantly. The primary (production) volume may not be accessible until the FlashCopy command completes.
- On the Snapshot Options dialog box in the Snapshot Resources pane, click Add.
NetBackup uses the information in the Snapshot Resources pane to correctly rotate through the clone LUNs when performing a FlashCopy clone 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 Backup Selections determine one or more source LUNs for which snapshots are taken for backup. For each source LUN that is specified in the policy Backup Selections list, you must provide the information detailed in the following steps.
- In the Add Snapshot Resource dialog box, enter the array's serial number in the Array Serial Number field.
- Enter the unique ID for the source LUN in the Source Device field.
- Enter the unique IDs for the clone LUNs in the Snapshot Device(s) field. To enter multiple IDs, place a semicolon between them.
Note the following:
The clone 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.
