Backup considerations with logical partitions

The process of backing up a logical partition is fundamentally the same as backing up a system without logical partitions. Each logical partition requires its own save strategy.

Here are a few items that should affect how you plan your backup strategy:

• It is important to remember that each logical partition functions independently of any others. Therefore you cannot perform a single, entire system backup. Instead, you need to back up each logical partition separately.
• As part of your backup strategy, remember that a processor failure, main storage failure, failure in the primary partition, or disaster shuts down the entire system. This might require you to recover all or some of your logical partitions. Therefore, plan carefully how you use your logical partitions and how often you need to perform a backup of each logical partition.
• You can generally perform these backups at the same time since each logical partition functions like an independent system. This can reduce the time that is required for performing backups.
• The system automatically maintains the configuration data for your logical partitions. This data is not saved to or restored from removable media.
• You should print your system configuration when you make changes to your logical partition configuration.
