At home I have a windows XP computer. What I do is FTP the contents of my documents folders to a linux server. In terms of cost, you can build a linux server very cheaply, possibly even by using your old components, think of it as recycling.
As well as providing a backup solution, it is also very usefull of you get a new system, all you need to do is copy paste your existing documents to the new location.
It may be something that you feel is worthwhile.
