Yes. Sure. Computers often crap themselves, but problem often exists between keyboard and chair, i.e. the actual users. Around 10 minutes ago an account executive at work called as all the site customisations are gone. It turns out she explicitly clicked on the option to wipe out all the customisation and had made no back up. Now she needs to dig up old backups from October last year and try to fill in all the missing pieces.
S*** happens. Some are big s***, however, a few are bigger!
