Help section needed - Backup/Restore of database

[OndrejValenta]

Hi,
could someone add a help section explaining how backup and restore of data is supposed to work.
Imagine a situation that we want to transfer a database from one server to another, is there even a way to do that. As I understand it, both servers would have to have the same master key right? But what if those servers must have different master keys.

Or is there some way to define masterkey while restoring data to new server?

Thank you
