Howso?  Using rsync with SSH wrapper allows you to not only alter only 
files that have been altered but as I understand it rsync will only 
copy changes within files over to the remote site.  SSH can be used to 
compress the transfer in addition to (of course) encrypting the 
connection and transfer, and it can be partially automated to allow 
login without passwords if you save the generated public key...

For the information supplied about what the customer would like done, 
using the SSH with Rsync may be ideal for low cost and reliable backups 
to a remote site.
