Happy World Backup Day! This is probably not your favorite made up holiday, but it is still an important one. How’s your backup system? Would you know what to do if your computer croaked right now?

The video above reminds us why backing up our files is so important. It’s also really easy to do using CrashPlan, Windows’ built-in tools, or another backup utility or service. You need more than one backup, too.

Remember also that your backups are only as good as your ability to restore your data from them, so today is a fine day to test your backups as well.
