Thank you for your message ,Matthias J. I understand the concept of server and cluster, but we need to backup the entire kafka service (topic, configurations in cloudera)
I have read 3 options 1.Kafka Backup 2.Snapshots of the file system 3.Mirror Maker2 but there is not much information. ________________________________ De: Matthias J.
