OT: syncing

[Payal Rathod]

Hi,
An offtopic quesiton, but I could not think of asking any other list 
where it might be answered.
I have a client uploading a few designs (25-30 Mbs) daily at a remote 
ftp server. We download them in morning. Since we have a slow 
connection we daily waste a couple of hours downloading it. Is there 
any way I can download them at night. The only thing is that I am not 
sure of the time they upload daily (it changes) and I don't want to 
download partially uploaded files (we pay per mb). Is there any 
technical/logical solution to this kind of problem? 

With warm regards,
-Payal
