Fortunately, today's magnetic tape backup systems are better, and less expensive, than ever. A tape backup drive lets you protect your valuable data quickly and conveniently. Get the largest capacity unit you can afford. That way, you won't have to replace the drive every time you upgrade your hard disk. Today, a 700MB or larger tape drive is a solid choice.
Most tape drives work the same way.
However, there are several different types of interfaces that you should be aware of. For instance, some tape drives use a separate interface card that you need to install. These drives simply plug into a connector on the PC's motherboard or an open floppy drive connector. Many tape backup drives are also packaged together with a software backup program. Selecting a new high-capacity tape backup unit will probably be more difficult than installing it.
