I have deployed the Couchbase operator helm chart on Kubernetes.
The backup pods were running correctly, but the incremental pod started to fail due to a rollback error.
It seems related always to the same vBucket, but I don’t know how to solve this.
Here it is the error:
(Cmd) Error backing up cluster: failed to execute cluster operations: failed to execute bucket operation for bucket ‘<bucket_name>’: failed to transfer bucket data for bucket ‘<bucket_name>’: failed to transfer key value data: failed to transfer key value data: failed to open stream: failed to stream vBucket 56: client received rollback, either purge this backup or create a new backup repository. See the ROLLBACK section in the backup documentation for more information
NOTE: The full backup works fine. Only the incremental is getting this error.
