Premium Edition

What does the backup and restore actually do, what settings does it carry?
Can I backup 1 appliance and restore the settings (domains, relay, etc) without the network coming across.

Also I cannot seem to get my key working.

Yes, you can backup and restore all your configurations with maillogs. But the version of backuped one should be same as the version of restored one.
