What is required before backing up the Runtime database?

Before backing up the Runtime database, no specific prerequisites need to be completed. This means that the backup process can be initiated without needing to shut down services or exit any active management tools. The database is designed to allow for backups to be conducted while it is still running, which is crucial for ensuring that data continues to be logged and accessed concurrently.

This capability is particularly useful in environments where downtime is not an option, as it allows for regular backups to be performed without disrupting ongoing operations or user sessions. Therefore, simply starting the backup process is sufficient, making it unnecessary to perform any of the actions suggested in the other choices.
