Redundancy and failovers

So I've set up my ignition to have a master and a backup. when my master goes down the backup starts and when backup goes down master starts. Now these are all automatic processes which are good.

The problem is when master goes down and backup comes up and then master comes back up the backup immediately switches over to master. I do not want this scenario, I want it to remain in backup for a while to collect all the tag data and any information to update to master then switch to master. When it just immediately switches over some data were not yet updated from backup to master.

In ignition redundancy config there is a setting called

Startup Connection Allowance

I've set this to the default 30000 milliseconds but I do not think this is the correct setting to achieve the above.

Anyone knows anyway to achieve this?

Set the master node's Recovery Mode to Manual:

Note, proper operation of redundancy expects both servers to run all the time under normal conditions. That is needed to maintain synchronization prior to failover.
