In essence, a backup using a type of format to store your files so that they are not all in one place. There is no point backing up your files in the same unit that originally was stored so you need to find another way to backtrack. For example, you can backup using a floppy disk, although these can not hold that much data compared to the amount that people use today.
A better option is to use CDs or DVDs. You can back up a large amount of data on a CD especially if you just back up Word documents. Of course, a DVD is much larger than a CD and be able to store more data on them. DVDs are more expensive though. It is easy to write data to a CD and most computers come with a rewritable disc.
If you have a lot of data to backup, then it will be better served by getting an external hard drive. These can come in sizes anywhere up to hundreds of gigabytes and therefore have enough storage space for videos and music. These are perfect if you want to backup the entire hard drive, but enough too if you just want to save your most important document in a safe place.
