Which is the best application to Sync two folders?

I want to know a very simple application to help me to keep and update backup copy of folders. I want to generate a list (alphabetically sorted) of all files (with size and last modification date) and subfolders of a folder that I choose, and save it to a legible file. I want to compare two folders to find differences between them and update the folder with newer files, instead to delete the entire old folder and copy the entire new folder.

You might want to use rsync for this purpose, it does pretty much what you want to do manually. So it won't give you a nice diff log, but it will sync your directories without copying existing/untouched directories and files.

If you're using Windows:

Check out how to setup rsync for Windows here or here. Alternatively, install Cygwin, a collection of tools which provide a Linux look and feel environment for Windows. It contains rsync as well.

If you're using *nix (Unix/osx/Linux)

rsyncis included in nearly every major distribution and is accessible through the terminal. If yours hasn't, get it here.
