The most common way to back up your files is by using some sort of removal media. i.e. CD\DVD’s, flash drive or external hard drive. The most common mistake is that once a form of media is used for backups the user will move his or her files to the backup media. This creates more storage space but doesn’t create a redundant backup because the information is still on one point of failure. The purpose of back up media is that if there is one point of failure there is another device with the same information on it. The user should copy files to their backup media instead of moving the files.

I guess I don’t understand the difference between moving and copying. Why does it matter?

Move and copy are basically the same with move it adds another step of erasing the original file. When copying, the file is copied and the original file remains where it was. For move, the file is copies then the original file is erased so the file appears to have been “moved” to another location.
