What must be done before restoring the Runtime database?

Before restoring the Runtime database, it is essential to shut down and disable the Historian service. This step ensures that no processes are actively using the database during the restoration, which could lead to data corruption or an incomplete restore. By shutting down the service, you effectively release any locks on the database files and ensure a clean state for the restoration process.

Maintaining the integrity and consistency of the database is crucial, and executing the restoration while the service is running could result in critical errors or data loss. Thus, disabling the Historian during this operation is a best practice, safeguarding the system and ensuring a successful restoration.
