[Samba] Samba/Windows file synchronizer (like rsync)?

[Kevin P. Fleming]

I have a need to (nightly) synchronize the contents of some shares 
between a Samba server and a Windows 2000 server. Ideally, the utility 
that does this would support all the Windows/CIFS file information, 
like ACLs, attributes, etc. We have about 100G to synchronize, but 
obviously once it's done the first time the daily changes won't be 
anywhere near that large...

I've thought of doing this using smbclient on the Samba machine 
itself, with both shares mounted at once, but still not sure there's a 
Linux tool that will preserve all the relevant file information.
