In this case, being backed up is a good thing.
Backing up your data is supremely important. Anyone who has had his or her laptop stolen or has been victim of a hard drive crash know how terrible the experience is of trying to recover everything that you've lost.
Having regular backups protects you from those sorts of things, including times of embarrassing user errors. Sometimes even installing the wrong thing can result in a freak accident that could take down your entire system.
Earlier today we discussed Microsoft's decision not to include the backup and restore feature into Windows 7 Home Premium and how that could be a disservice to general computer users. Those who opt for the Professional or Ultimate versions will be able to utilize the built-in software, however.
Mac users have one of the best backup options with Time Machine, which automates the entire backup process and makes restoring old files and configurations simple.
Regardless of backup solutions, the process of protecting one's data is up to the user.
So, our QOTD is: how often do you backup your data?
Also share with us which piece of software and method you use to backup your data. And if you don't backup your data, please tell us why not!
