After reading almost this entire forum, all the documentation, and a few days of experimenting on my own, I am still seeking the best, most reliable way to backup my hard drive. I have made a full backup, and then an incremental that took as long to make and was as large as the original image. I have had advice here in the forum to forget about incrementals, or also to do incrementals daily, full images weekly... and I am still not sure. Last night I set a 'scheduled image' for the first time (incremental), and when I got up this a.m., I saw an error saying "failed to open secure zone for exclusive access"... but also a message saying the image was created! () So, maybe I do not want to use the secure zone at all, eh? I need to get this set up and move on. My whole purpose in buying T.I. was on a recommendation from a current user, who suggested I could "set it and forget it" - but How?!? Your suggestions are greatly appreciated!
