Hi All,
Anybody use to backup graylog configuration, please share your experience.
yes. it’s good, and useful.
copying server.conf to somewhere, and doing a mongodump and copying that somewhere are indeed good.
you missed the plugin folder 
Well then, I guess someone will have to re-install them after recovering 
What is your suggestion ?
Could there be a backup and recovery official documented procedure?
the docs are open source - contribute!
How about archive log day by day ?
It’s not graylog configuration.
GL stores log in ES. So you have to backup ES.
