I've read the differences between incremental and differential, over and over and over and it's just not soaking in as to the differences. I've got 3 questions. 1. I have a full backup of my C drive on my external hard drive. I've got it set for incrementals every 2 days. Right now, I have a full backup and 2 incrementals. If I ever need it, what exactly does it do?.....Recover the full backup and THEN the 2 incrementals one at a time, all at once, or what? 2. I want a backup of everything on my C drive (i.e. programs, OP system, documents, pictures, home video, etc.). Should I do a backup of the C drive with weekly incrementals or differential? 3. Should I also do a "clone" for my programs? (I don't want to reinstall all of them). This is a great program with so many options, I'm undecided? Thanks!
