There are a few ways to backup your data, but probably the easiest is to backup to a USB Stick or an external Hard-Drive. These are external drives that you can plug into a USB port on your computer and then copy files to and from it.
One of the main advantages of this type of backup is that unlike a DVD backup, you can add, remove, and modify files that are on the USB Drive.
Before we begin, it is important to understand the sizes used to describe files on a computer, as well as hard-drives. Most USB Device’s space is measured in Gigabytes. A Gigabyte is a unit of measurement and is fairly large.
To give you an idea, you could probably fit at least 500 high quality pictures in 1 Gigabyte or several thousand low quality pictures. Text files are much smaller, so you could easily fit thousands of regular sized text documents in 1 Gigabyte.
Music and videos are much larger and depending on the video camera or video quality, you might be able to fit a couple of full length movies in 1 gigabyte or even only a few minutes of video, if it is very high quality.
USB Sticks are small devices, often called thumb drives, which plug into a USB Port on your computer. They are sort of like mini hard drives, which you can transfer your data too and offer the advantage of being small and easy to work with.
The less expensive thumb drives, like those you get for under $30, usually hold a lot less data than an external hard drive. They are often best suited for moving files between computers and backing up text documents. When storing movies and music, and to a lesser extent pictures, a USB Drive can be filled up very quickly!
There are some USB Sticks that are much larger, like the Kingston Data Traveler, which holds 256 Gigabytes of data, but they are also much more expensive, around $600.
External Hard-Drives usually hold a lot more data than an USB stick. As the name implies, they are similar to the hard-drive inside your computer, but designed to be easily transported without having to actually install it inside the computer.
They are typically two parts: the hard disk itself, which is surrounded in a plastic case for protection and a detachable cord that plugs into the USB port on your computer.
From a value standpoint, you will usually get more space for less than when shopping for a USB stick. It is a good idea to get one that does not require external power cord, this way you can always use it without having to try to find a plug or carry around an extra cord. Some external-hard drives use a special cord, which has a split in it, to plug into two usb ports.
When selecting a USB Device, you want to make sure that it is big enough to hold all of your pictures, documents, and files, while also providing room to grow.
USB Thumb Drives are usually much smaller than an External-Hard Drive. It is not common to see an external-hard drive that is less than 80GB, but you will often find thumb drives that are only a couple of GB in size.
In most cases, if you have only text documents that you need saved, you would probably be fine with an 4GB or 8GB usb stick.
For those that have a lot of pictures, music, or videos, it is probably a good idea to go with at least an 80GB external-hard drive and in most cases, it is better to go with an external-hard drive that holds more than 320GB to be safe. This will provide plenty of room to grow.
To determine how much space you need, it is a good idea to check the folders on your computer to see how much space you use. First, determine the size of your current hard-drive. Then, check to see how big your picture, video, and document folders are.
This will give you an idea of how much space you have, how much space you are using, and how much space you need to have a little padding!

One of the cardinal rules of computers is ALWAYS make a backup. It is not a matter of if your hard-drive will fail, but rather when your hard-drive will fail! There are also many other things that can happen, like dropping your laptop, computer viruses, water damage, electrical issues, which can result in a fried hard drive.
Making a backup of your data is essential to ensure that all of your pictures, documents, and music is safe and will not be lost.
Unfortunately, this is something many people never do. It is very easy to get comfortable storing all of your pictures and family movies on your desktop computer, thinking this is safe. Usually, it only takes this happening once to realize the importance, but by that time it it too late!
All too often, I have to tell people the bad news that their hard-drive has gone bad and the data lost. So, Backup, backup, backup and then backup your backup!
