Thank you for posting Kim -- I think it says something about the company that you saw this post and took the time to register and reply.
I actually thought it might be something to do with cache settings and tried a ton of them with no luck. Then I installed the new version (which is a paid upgrade that I haven't yet purchased) in hopes that that would solve the problem, but no luck.
The crazy thing is that it's been working well for quite a while and I don't know what suddenly caused this trouble -- the only thing I can think of is that I replaced and cloned the hard disk that holds the downloaded backup files and maybe that confused it into thinking the files needed to be redownloaded.
Thinking that might be it I let it redownload a 100 gb of files, but it was never satisfied and each night it wanted to re-download the same 100gb over again..
HOWEVER, I believe it is now working -- and I'll show you the option that I set that seems to have made the difference:
I don't know if that option spontaneously unchecked -- or more likely that what's happened is something went wrong making the program think the files have changed, and without that option it can't verify that without redownloading them..
Regardless, for now all seems to be working well again. I will report if it happens again -- and if anyone else has the same problem they should check out that option.
