How do I backup my data?

The process of data backup involves storing data on a disk or drive separate from your primary computer. This can be on a floppy disk, a CD-ROM or DVD-ROM, a key drive (USB-stick), a Zip disk, a remote computer or an online service. The emphasis is on having two or more copies of your files, in this way if something happens to one then you will still have the other.Say, for example, that you are writing a report for your business. You can save this report both on your computer and onto a 3 and a half inch floppy disk. If anything happens to your computer, say you are infected by a virus which deletes all of your documents, once you computer is fixed you still have access to your report on your backup.
