The offset is necessary to avoid port conflicts when starting the colocated backup. If both brokers try to use the same ports then one of the brokers won't work. > Does that mean backup server 1 will create new listen port 5545 to > live server, and backup server 2 will create new listen port 5645? Yes. However, there's a typo in the documentation. It talks about a connector using port 61616 and then backups using 5545 and 5645 due to the port offset. However, it should say the backups will use 61716 and 61816 instead.
