Isn't any SQL server crash safe? I.e. they should handle a system power-loss and gracefully recover (journals). A filesystem snapshot is equivalent of a power loss. You need to configure your databases accordingly.

Most of maria/mysql have enabled innodb doublewrite enabled by default:

But just in case of Active Directory... I really really want to have consistent snapshot/backups 🙂
