Many years ago, I worked as the IT director for a school here in Massachusetts. It was a multi-faceted job that included maintaining a file server, a backup server, well over 100 machines and, finally, a help desk for about 125 people. I have some amusing stories from those years, as well as an important lesson: never have a single point of failure.
Redundancy was the name of the game in my previous job. For example, our file server was connected to something called an “uninterruptible power source,” or UPS. A UPS provides electricity in the event of a power outage. That way, if a storm knocks power out, I still had time to get to our computers and shut them down properly.
I also ran a backup server that saved its daily and monthly backups to several locations. If one of those backups failed for whatever reason, I could rely on one of the alternates to provide what I needed. What does this have to do with daily life? Plenty.
As Leo Babauta once said on Zen Habits: “I’ve seen people pay $1,000 to hear speakers at a conference and only have one pen to take notes.” If that pen breaks or runs out of ink within the first five minutes, you’re out of luck. The simple act of bringing two or even three pens can eliminate a potential problem.
Consider where there might be a single point of failure in your life right now. I did some brainstorming of my own, and came up with this list:
- More than one flashlight. Here in semi-rural Cape Cod, we lose power at the drop of a hat. Keeping three inexpensive flashlights in the closet eliminates some stress.
- Car keys. Most new cars are sold with a pair of keys. But that’s not always the case with used cars. If you’ve only got one key, spend the money to get a second.
- Charger cables. These things aren’t really built to last longer than a couple of years it seems, yet we don’t replace them until they become a frayed fire hazard. Keep a fresh one in a drawer so you can swap it out with the original before plugging it into the wall becomes an act of pure optimism. Additionally, having multiple charging cables in different locations (such as one at your home, one at your office, one in your briefcase) means that you don’t ever have to worry about forgetting a cable when you need it most.
- Important documents, like birth certificates, marriage certificates, social security cards, etc. My practice is to put the originals in a safe deposit box and keep photo copies on hand. If I lose/damage the copy it’s no big deal, and I can always retrieve the original if I need it.
Finally, and you probably saw this coming, I’ll say please make multiple backups of your important digital files. A solution as simple as Dropbox makes it very easy to have files both on your computer and safely on their servers. Additionally, Carbonite and Crashplan will back up your computer in its entirety. (Erin wants you to know she’s a fan of Backblaze.)
Make a list of the single points of failure in your life right now, and see if you can fix them. Someday you might be very glad you did.
