following following instructions from Aswani:

Use db_json_exim.py from 'config_api' container
docker ps -a | grep config_api

backup
1)docker exec -it <config_container>
2)cd /usr/lib/python2.7/site-packages/cfgm_common
3)python db_json_exim.py --export-to db-dump.json

restore
If u want to try restore on same cluster
1)stop Cassandra ,zookeeper and kafka containers in all nodes and delete config
config-location: /var/lib/docker/volumes/config_*
2)Start Cassandra and zookeeper containers
3) python db_json_exim.py --import-from db-dump.json
4)start kafka containers on all nodes

Thanks,
