More granularity for backup/restore

[stvboyle]

This is really a feature request.  The ability to backup and restore parts of the configuration is great.  I love the ability to backup the dnsmasq config on one box and restore it on another.  I would love more granularity, for example I cannot backup and restore just the Load Balancer config.  Support for most or all of the different sections of the config would be great.

I was able to do a full backup from each of two hosts then copy the loadbalancer section from one config file to the other to make it work.
