> Why backup server need to do offset? 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.

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.
