If you have Windows or Vista, then you have free backup software on your computer. The problem is no one really has seen the extent of backup that Vista’s and Window’s provides to you. In short, when you backup your files, they are there when you need them, but when you have to reformat your hard drive due to some unforeseen occurrence, God forbid, you will not have a single file on your hard drive. For this reason, backup means to save files to disks, tapes, other hard drives, zips, etc. These are not free backup software solutions, but they are proof that you will have backup when you need it. There are also sites online that offer you free backup software and storage. This means that your files will be publically uploaded to the Internet. It doesn’t mean that everyone on the Net has access to the files, but it does mean there is some exposure there that if a good hacker had the skills, he or she could perhaps gain access to your files. On the other hand, services offer you free backup software that allows you to store your files on a mainframe computer somewhere and your files are protected.
