Plan for a Crash. Have a Happy World Backup Day!
“More and more, the fragments of your life exist as particles on a disk mounted inside your computer—disks susceptible to temperature changes, power surges, fire, theft, static, and just plain wear and tear. Hard drives fail. It’s a fact of computing life. It’s not a matter of whether your computer’s disk will stop working; it’s a matter of when. The question is how much it will disrupt your life—and it won’t, if you have a backup copy.
Backing up your data is the dullest but most indispensable thing you do on your computer. Here’s how to automate regular backups for your computer, both on-site (to an external hard drive or another computer), and off-site (to the internet). This system can even email you if something goes wrong, so it’s the ultimate set-it-and-forget-it situation. After you get this up and running, you’ll never have to worry about losing data again.”
