Thanks for all the suggestion thus far!
I've installed sync toy and played with syncback for a while!
Sadly unless i'm missing something, syncback doesnt seem to be able to detect directory changes (only) (which i make quite often, since i'm new to this organized backup thing) but instead telling me that what files and where they are missing.
As popo have mentioned, i will have to make the changes manually and use them as a reference. That definitely helps, instead of me remembering all the changes that i have made.
However, just, if they can be automated
I'll look into sync toy and the super flexible file synchronizer... boy that's a long name
Thanks again for all the suggestions, appreciate them
Other suggestions are still welcome! I don't mind paying but again they should be reasonable priced (Well this is sort of subjective... i guess under 100 dollar?).
