I tested mine involuntarily. I enabled full disk encryption on my the main drive of my server, ignored all the warnings and then noticed, that the whole drive was formatted.
Luckily, all the important data was in my backups, I lost some compose files and the database of my paperless ngx seems to be broken (although theoretically, I am sure I could recover that data, I just don’t have that time and there is nothing that important on there).
Yeah, I now do that aswell.
I learned from my mistakes
