which Windows and Programs folder files do not need to be backed up?
I use Retrospect Professional to back up all my systems. I like that Retrospect retains old versions of files, not just the current version. (http://www.retrospect.com). Highly recommended, btw.
Here is my question. Rght now I have Retrospect set to back up all files on my C drive (on all systems), except for obvious temp files, hibernation and swap files, etc. The C drive contains just Windows and installed programs. I keep all user data, photos, music, etc., on other drives. Some nights I find Retrospect wanting to back up 3-5 or more GB. I know some of that is daily updates for things like AV signature updates.
Are there folders that are used just for these kinds of daily updates? is it important that I back up the ProgramData folders? Any other folders that I can safely ignore?
