Even though it's something we all know we should be doing, for many of us, backups aren't carried out often enough. Perhaps one of the biggest reasons for this is a lack of suitable storage media – and that's our topic here. It's not just the hardware that gets in the way, though; the amount of effort it takes to complete the back-up process is also a hindering factor. If your only option is to copy your hard drive onto a stack of 50 CDs, it's not a chore that's going to get done any time soon, or often. The key to data protection is making the back-up process as quick and easy as possible, and thus making sure it gets done frequently. Having storage media of adequate capacity is vital, but equally important is keeping to a minimum the amount of data that has to be backed up. Just your documents?An important consideration is whether to back up your entire system or only data files such as emails, documents, photographs, audio tracks and so on. Backing up an entire system involves disk imaging, which, as the name suggests, makes a copy of everything on your hard disk – data, programs, settings and all. This means that if you use a recent disk image to recover your PC after a crash, it'll look and feel exactly as before. In many ways this sounds like the ideal solution, but inevitably there are some downsides: because you're backing up so much data, the process is slower and you need a larger storage solution.
