Does LabTutor Server support Volume Shadow Copy?

No. The internal database engine used by LabTutor Server does not support using Volume Shadow copy to create backups while the service is running. Database Snapshots are automatically configured to occur daily, making the database unavailable to volume shadow copy. The time for the daily database snapshot to occur is able to be changed in the LabTutor Server Administration pages Server > Configuration >Database Snapshots. Please consult the LabTutor Server help for more information. 

This information is valid for LabTutor v4.0 or later.
