Hello
I've read the How to backup Neo4j Running in Kubernetes it seems that either the tool has change since the redaction of the article or that I'm not using the correct version of neo4j.
I've deployed neo4j with helm3 in a k8s 1.17 cluster (hosted by ovh.com)
helm install --namespace neo4j db stable/neo4j --set imageTag=4.0.3
I would like to do a DB backup and restore but I'm facing two issues:
neo4j-admin backup
but I only see neo4j-admin dump
with no parameter to specify host/user/password when running the image withkubectl run -it --rm neo4j-admin --image=neo4j:4.0.3 --restart=Never --namespace neo4j --command -- bash
Any ideas how to dump/load or backup/restore a neo4j community db running in a kubernetes cluster ?
best regards,

There is a difference between dump/load and backup/restore. The dump/load commands are strictly offline operations, while backup/restore are online operations.
To do this with kubernetes, you should use the online option of backup/restore, and the articles you're following are the right ones to go to.
The existing operations manual documentation for Neo4j is rather focused on running in the context of an actual machine or VM rather than running in kubernetes, where special considerations apply.

Thank you for the semantic clarification. Indeed backup/restore is what I'm after.
When we read the code associated with the post, the neo4j-admin backup
command is used.
But using the latest neo4j-4.0.3
docker image, I don't see the backup
option.
Is that a difference because of the version 3.4
vs 4.0
or because your code uses the enterprise version and I'm using the community one ?
$ kubectl run -it --rm neo4j-utils
--image=neo4j:4.0.3 --restart=Never --namespace neo4j --command -- bash
If you don't see a command prompt, try pressing enter.
root@neo4j-utils:/var/lib/neo4j# ./bin/neo4j-admin -V
4.0.3
root@neo4j-utils:/var/lib/neo4j# ./bin/neo4j-admin

The backup/restore is only available in the enterprise edition.

It's true that backup/restore is an enterprise feature. Additionally, there are big differences between 3.5 and 4.0 that bear on the configuration
