[ale] Copy server

[Chris Fowler]

I'm using rsync for backups but I want to sync a server with another and
I want to make sure I get the CLI options correct because I have only
once chance to get it right!

I have two servers that are identical.  One is a master and the other a
slave (MySQL terms).

The software is in /opt/SAM on both systems.  Up until now they were
identical but I've made changes to files on the master so I want to do a
copy.

I want to use rsync to sync master:/opt/SAM to slave:/opt/SAM.  On the
slave I want to delete any files that do not exist.  

rsync -avz --delete -e ssh root at master:/opt/SAM /opt/SAM

I want to exlcude /opt/SAM/mysql 

I don't want to copy the master's data because that would mean I would
have to reinitialize the slave.
