Best tool to use to synchronize backups?

What's the best tool to use to synchronize offline backups? One that at least would ignore duplicates, and just copy files with newer timestamps/bigger file sizes, also deletes files that are no longer on the source folder.

Not asking too much, am I?

Thanks, actually I just need a simple solution for the user that will essentially "mirror" what he has on his windows laptop to a specified folder on the NAS drive. He'll plug it in for "syncing" every 2-4 weeks and expects the software to do the job while he sleeps. Sort of like a private Dropbox, if you will.

use windows backup

Hmm windows backup has really poopty UX designs. Adding folders one by one without the options for batch edits is a real pain!

I use GoodSync. I've used it to sync data for a few years, and also for backing information up locally. It's possible to back up to a cloud service also, if you have one.
