Backup/restore of region controllers

[Andres Rodriguez]

Hi Junaid,

I just wanted to make a clarification. You don't really *need* to backup
/var/lib/maas/* for most cases. The Region Controller will automatically
re-generate everything (all config files, re-import images, etc). So:

1. If you have both MAAS Region and Rack on the same machine, there's
definitely no need to backup /var/lib/maas/*
2. If you have additional stand alone rack controllers, you need to make
sure the secret is updated to the one re-generated in (1) in order for the
rack controller to re-connect to the new region controller.

Hope this helps!
