[Samba] Samba, rsync and a newbie sorting it out...

[qk]

All, 

I'd like to use rsync as a way to back up Windows devices on a network, 
pulling data off of the Windows boxes and putting it onto a Samba share. Is 
this even possible? I suspect I either need some sort of rsync 
implementation on Windows (ha!) or I need to have Samba know to "reach into" 
the boxes and get the info for rsync-ing. Doable? A fool's errand? 


The setup: 

* In-home LAN consisting of 3-4 PCs running W2K and WXP; one FreeBSD server 
running SAMBA. 

* No PDC; everyone is on the same workgroup and everyone has equal and 
unfettered (no login/password and all can overwrite) access to /storage on 
the BSD box via Samba. 

Ideal situation: Designated directories on the windows boxes are rsync'd 2-3 
times a day during times of low use. Alternate: The whole Windows drive is 
rsync'd onto a Samba share on the BSD box, once a day. 


Many, many thanks in advance!
