Resolution: Not a Bug
Backup Image in CND 2.2.0 GA is based on cbbackupmgr 6.6.2
Our docs suggest that with this image in 2.2.0, we can take backup of Couchbase Cluster from 5.5-6.6
This is not valid as cbbackupmgr 6.6.2 doesn't support backup from non 6.6 cluster.
This was confirmed by running a backup test with Operator 2.2 running 5.5.0 CB cluster and the test case failed : http://qa.sc.couchbase.com/view/Cloud/job/k8s-cbop-gke-pipeline-2.2.x/50/console (Operator framework 2.2.x doesn't support server versions pre 6.5.0)
