Recovery procedures

The procedures provided here are based on a system topology with two peer master servers (server 1 and server 2) and two replica servers (server 3 and server 4).

Server 2 is acting as a fail-over master, meaning that it does not accept updates directly from client machines unless server 1 is taken offline.
This diagram shows the two peer servers, server 1 and server 2 with bidirectional update flow between them. Each of the peer servers has a unidirectional update flow to each of the replica servers, server 3 and server 4.
