You have probably invested a lot of time (a lifetime?) and effort in creating and accumulating your personal data. Your family tree, thesis, digital artwork and photography, a manuscript or a musical score, home made videos, your will and other legal documents are just some of the kinds of personal data you may have compiled. They are important to you, and possibly important to others, and are well worth safeguarding.
Consider whether you can afford the time and effort to replicate your personal data if something happens to your computer. And is it possible at all to replicate it?
