Sure, they make it cutesy, but you have no idea how often this actually happens. Disaster recovery in most orgs is not given anywhere near the attention it deserves. If it can happen to Pixar, it can happen to you.
So, um… do your backups kids. And make sure you have offsite backups as well! I use Crashplan myself (which works on Win, Mac and Linux) though was using Haystack's Arq on my Mac until very recently as well. Seriously, the minimal cost is nothing compared to losing photos or critical docs. Believe me.
And yes, if you must know… I do have a similar story though it did not end nearly so well. One of my team inadvertently nuked an organization's entire document database and the disk the only backups were on at the same time.
