How often do you perform a computer backup? Probably not often enough! Well, if you aren’t already on a regular backup schedule, now is the time, because March 31st is World Backup Day! Author: Mike Cobb

Do you ever think about how much stuff we have lying around just in case something breaks? Batteries, lightbulbs, spare tires, duct tape, the list goes on and on. But why? Why do we live in a constant state of “what if?” Because the minor annoyance of storing batteries and lightbulbs far outweighs the inconvenience of not having them when needed.

A computer backup is no different. Just like electronics that need batteries or lightbulbs, there’s a high likelihood your computer’s going to fail at some point. And when it does, you’ll be prepared if you’ve been diligent about your backups!

A whole host of issues can cause data loss, from malware to your device’s age. Even simple user error can cause catastrophic damage. Without a reliable computer backup, these issues often result in permanent data deletion. And unfortunately, recovering your lost data isn’t as simple as switching out some batteries or adding a little duct tape.

One of the easiest ways to back up your computer is with an external hard drive. Here’s how to back up your computer to an external hard drive.

Step #1: Determine what should be on the computer backup

Almost everything on your device falls into one of two categories: personal items or program files. Depending on how you use your computer and what’s important to you, you may want to back up one, the other or both.

Personal items
Personal items are just what they sound. This is content you’ve personally created. Data like documents, spreadsheets, photos, music and movies fall into this category. And yes, even though you probably weren’t the original creator of most of your music or video files, you generated the file by saving it to your computer, so those count!

For most users, personal files are the most important. When you decide what you want to include in your hard drive backups, these are what you’ll focus on. And it’s easy to see why. These files are usually irreplaceable and not saved anywhere else.

Program files
Program files include your operating system, settings, apps and any associated files. In most cases, you can easily replace program files by re-downloading.

But you may want to include your program files in your backup if you have specific, customized settings. Saving program files on your computer’s backup will save a lot of time and effort, especially if you like to tweak your registry and update often.

Do note that some types of backup software don’t have the capability to back up program files or operating systems—only personal files. But saving both types of data on your computer backup is your best bet for recovering from data loss as quickly and efficiently as possible.

Step #2: Select the right external hard drive for your computer backup

There are a few considerations before selecting an external hard drive for your computer backup. There are thousands of makes and models, each with its own unique set of metrics. Ask these questions before settling on an external hard drive.

Question #1: How much storage do I need on the external hard drive?
You’ll want a drive with at least as much storage space as the computer it will back up. If you don’t know the capacity of your internal hard drive, 1TB is a decent place to start for most users. Toshiba’s Canvio portable hard drive lineup offers a choice of capacity up to 4TB that fits your storage needs.
