So why not create an extra start it only when you want to make a backup, wait until it is up to date, stop it and then stop it to back it up?

Hi all,
We are looking for a proper solution for backups of monitor (all maps that they hold). On the internet we found advice that we have to stop one of monitor, back it up (dump) and start daemon again. But this is not right approach due to risk of loosing quorum and need of synchronization after monitor is back online.
Our goal is to have at least some (recent) metadata of objects in cluster for the last resort when all monitors are in very bad shape/state and we could start any of them. Maybe there is another approach but we are not aware of it.
We are running the latest nautilus and three monitors on every cluster.
Ad. We don't want to use more monitors than thee.
Thank you Cheers Michal -- Michal Strnad
