# 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 loads its initial state from that file. You can save and load a persistence state for in-memory or disk-based clusters.

You can use this facility for nightly backups, during upgrade migration, or to migrate a persistence cluster to a new physical location. Clients are interrupted for this operation.

See the following steps:

Procedure
1. Suspending a Persistence Cluster
2. Saving the State of a Persistence Service
3. Restarting a Persistence Cluster with Saved State
4. Starting a New Persistence Service with Saved State

Backup and online compaction cannot run at the same time. For details about using the persistence service for compaction, see Compact Disk Persistence Files with Persistence Service Online.

For information on disk persistence backup, which does not interrupt clients, see Disk Persistence Backup and Restore.
