Any good SyncBack SE alternative for OS X?

[The_Prodigy1982]

On my previous Windows system I always used SyncBack SE, and I really loved it!
However, now that I've gone to OS X, I'm looking for a good alternative.

Is there any, what do you guys recommend me?
It needs to have the following options;

1) Simple 1-click
2) When backing up for the first time, of course there needs to be a complete backup of the files you want to back up.
But after that there needs to be an option to override the older backed up versions, with newer versions that you might have edit in the meantime.

Sorry, my mistake... I forgot to mention that besides Time Machine (which I already use, and LOVE) I also have a Dropbox account.
I have this Dropbox account linked to my iMac harddrive in a separate folder, and it's quite convenient to ALWAYS have a recent backup of every file, without having to browse through your Time Machine backup.

* So basically I'm looking for an alternative to SyncBack that backs things up to another folder...
(separate from using Time Machine)
