Backing up and restoring the configuration data

You can back up all the current configuration settings of your KSYS environment as a snapshot. A snapshot preserves the configuration details of the KSYS environment at a specific point in time. For example, a snapshot file contains the information about the existing sites, details about the managing HMCs and the managed hosts in a specific site, and the storage device details in the site. You should back up your current configuration settings after you configure the sites, hosts, HMCs, and storage devices initially.

If you save a snapshot of the current KSYS configuration settings, you can restore the configuration settings later by applying the snapshot on the KSYS configuration. The snapshots are useful during node upgrades or environment malfunctions because snapshots eliminate the need to reconfigure the sites, hosts, HMCs, and storage devices. For example, if the KSYS node must be reinstalled, you can use a snapshot and do not have to re-create sites, hosts, and other resources.

You can save the following types of snapshots:

Detailed configuration data

To restore the DETAILED type of snapshot, the version of VM Recovery Manager DR must be the same as the version when the snapshot was captured. The snapshot must be captured on the home site only, and must be restored only on the home site. When the snapshot is restored, ensure that all VMs are on the home site.

If you capture a snapshot on a lower version of VM Recovery Manager DR, you cannot restore the configuration settings on a higher version of VM Recovery Manager DR.
