In the human body, blood is sustains life delivering oxygen, nutrients, and other essential substances and so is the same for the data or files on your PC. As computers play a bigger role in our lives, the information we store on them becomes increasingly important. For small businesses, data loss can be disastrous and for home computers, it can be heart-breaking. Data files consist of but are not limited to: music (mp3, itunes), documents (Word, resumes, reports), pictures\videos (camera or camcorder family, friends, kids, vacations), financial files (Quickens, Quick Books, Microsoft Money) spreadsheets (Excel, Access), bookmarks, etc to name just a few.
While you might think that the chances of having a major loss of data on your computer or even having your entire computer crash are very small, disasters happen and it is always best to prepare for the worst, especially when it comes to something as irreplaceable as your files.
