[wplug] rsync and preserving owner/group

[Andrew Biggadike]

I'm using rsync through ssh to backup certain directories of my laptop
to my desktop, but it doesn't preserve the owner and group of my files. 
The man page states that typically only root can set file ownership.

What would be the most secure way of configuring this so I can preserve
file ownership and group settings?  Logging in as root doesn't seem like
a great idea.
