The link I posted showed it in config format.  I was providing an 
alternative, since the OP's already doing weird acrobatics with -e:

>>> -e 'ssh -p <port> -o ServerAliveInternal=10'

But, as you point out, this is probably better placed in an 
~/.ssh/config:

Host rsync-reverse
HostName hostname.net
User root
Port <port>
ServerAliveInternal 10
ControlMaster auto
ControlPath ~/.ssh/master-%r@%h:%p

Then, the commands from before:

>>> /usr/bin/rsync -avrz --human-readable --progress --update --perms --ignore-existing -e 'ssh -p <port> -o ServerAliveInterval=10' --delete --relative root@<hostname.net>:/etc '/shares/internal/<dir>/'
>>> /usr/bin/rsync -avrz --human-readable --progress --update --perms --ignore-existing -e 'ssh -p <port> -o ServerAliveInterval=10' --delete --relative root@<hostname.net>:/root '/shares/internal/<dir>/'

1. don't need the '-e' option ('ssh' is the default, and the options 
will come from ~/.ssh/config)
2. can use the Host specified above to shorten the source
3. don't need the redundant '-r' and '--perms' (-a includes both)

/usr/bin/rsync -avz --human-readable --progress --update --ignore-existing --delete --relative rsync-reverse:/etc '/shares/internal/<dir>/'
/usr/bin/rsync -avz --human-readable --progress --update --ignore-existing --delete --relative rsync-reverse:/root '/shares/internal/<dir>/'

And, if the sources are really /etc and /root, you can just 
combine them into the following (and the --relative is redundant because 
it's based at the root directory):

/usr/bin/rsync -avz --human-readable --progress --update 
--ignore-existing --delete --relative rsync-reverse:'/etc /root' 
'/shares/internal/<dir>/'

(in which case you might not even need the ControlMaster/ControlPath 
stuff.)
