Saving and Loading Persistence State

The persistence GUI includes a facility to save the content of a persistence service’s stores to a file. When a new persistence service starts, it can load its initial state from that file. You can use this facility for nightly backups, during upgrade migration, or to migrate a persistence cluster to a new physical location.

See the following three subtask topics.

Procedure

Suspending a Persistence Cluster
You can suspend all the services in a persistence cluster, however, you cannot suspend a service individually.
Saving the State of a Persistence Service
Administrators can save the state of suspended persistence services.
Restarting a Persistence Cluster with Saved State
Administrators can restart a persistence cluster using previously saved state.
Starting a New Persistence Service with Saved State
Similar to restarting a persistence cluster with a saved state, administrators can restart a persistence service in a new cluster using previously saved state from a different cluster.
