Also remember that even though a backup site might be physically closer to the 
system site, the route that packets take on the internet might be a lot 
further than you think. It would depend what isp you're both using and their 
routing tables.

An example I have is that the next door neighbour is using a different isp to 
me, and packets between our servers go via a capital city in another state - 
1000km away...

It's worth doing traceroutes and pings to find out which will be quicker. 
Especially when using rsync to back up the system, return trip time will make 
backups a lot faster once the initial backup has completed, due to the time 
it takes to send checksumming information is affected more by ping time than 
pipe size.
