The "Backup Entire Database" function in LimeSurvey enables users to export all application data, including surveys, participant information, and responses, as a .sql file that the browser prompts you to save. This feature is accessible through the Configuration menu.
Use this backup before transferring LimeSurvey to another server or upgrading manually (without ComfortUpdate), or as a security measure when making code or configuration changes.
Note on ComfortUpdate: If you use LimeSurvey's ComfortUpdate service, the system automatically generates database backups in a temporary folder on the server, eliminating the need for manual backup during updates.
