Keep local directory up to date

My company uses samba as the main file server. I would like to backup samba (remote) on my home machine. Would it be possible to add the feature "to keep the local directory up to date".

There's no way how to watch for changes in remote directory apart from repeatedly re-reading it in regular intervals. In upcoming versions WinSCP will allow to synchronize the directorins using command-line. Together with Windows scheduler you will be able to set up this.
