Why does my server reset the database when its restarted?

A few days ago, we had registered some patients and create a new user in OpenMRS, the server restart because it would have electric power for a few days and when I turn back the database seems he made a “restore” before the last changes I made.

SO: Windows Server 2012 OpenMRS Version: 1.11

I have been troubleshooting Windows boxes for the last few days, I suspect that probably your database crashed and the restore did not include the sample data that you entered.

Can you enter a patient then restart your computer to verify if the patient information is lost
