Hello Only last month (end September) I purchased TI 11 Home edition and (with the very kind help of members of this forum)successfully created a bootable dvd and completed a full back up to an external drive. Over this weekend I received a free upgrade to TI 2009. Looking at it I see the One-Click Protection tool and I am not sure whether I need to use it so recently after already creating the full back up mentioned above. Even after reading the Help section, I am not at all sure if what One-Click Protection is all about. As a "silver surfer" with limited computer knowledge, even after using google, the terms "system volume" and "master boot record" as used in the One-Click tool mean little to me (except they appear important!!) If the advice from more knowledgeable forum members is to use the One-Click Protection tool now, do I back up to my external drive as I did last month ? Many thanks in advance for help !!
