backup via an intermediate drive

[Cavan Fyans]

Hi,

I have a backup server running for a media company i work with that's  
being moved offsite to a server house.  Obviously I still want to run  
the regular backups but the problem is that the outgoing connection  
from the companies studio can not handle the amount of data that needs  
to be transferred.  Due to this the server housing company has  
provided a service through which they will transport the data to be  
backed up in person, on a mobile drive.

The question is, can I run the same Rsync service but transfer the  
updated/changed files from the studio onto the backup server via the  
intermediate drive?

Thanks.
Cav.
