Configuring a NetBackup policy for IBM_StorageManager_FlashCopy
For general help setting up a NetBackup policy, refer to the NetBackup Administrator's Guide, Volume I.
The following procedure focuses on the IBM_StorageManager_FlashCopy method and its parameters.
To configure a NetBackup policy for IBM_StorageManager_FlashCopy
- In the NetBackup Administration Console, click the Perform snapshot backups box on the policy Attributes tab.
- Click Options to display the Snapshot Options dialog box.
- In the Snapshot method pull-down list, select IBM_StorageManager_FlashCopy.
- You can set the following parameters:
Maximum snapshots (Instant Recovery only) parameter
The maximum value is 4 snapshots per source device.
Repository % of Base (100 for Instant Recovery)
Determines the size of the IBM repository logical drive as a percentage of the primary device (base logical drive). The size can range from 1% to 100%. The more write activity that occurs on the primary drive, the more space the repository logical drive requires.
If the size of the primary is 500 GB and you set this parameter to 30%, the repository drive is set to 150 GB (30% of 500).
For Instant Recovery backups, the percentage is set to 100% regardless of any value that is entered here. The default (0) does not mean 0%: it means that the array determines the size of the repository drive (usually 20%).
For more details about the repository logical drive, refer to the IBM System Storage DS4000 Series and Storage Manager document.
