Are for what? A blackout?

IMO this shouldn't damage the complete configuration. Assumed you were
editing the configuration, while a blackout happened, likely something
of the reconfiguration would get lost.

Does somebody know, if some file systems could cause a complete loss, if
e.g. a blackout happens at a inconvenient moment or could some kind of
hard disk be the culprit?
