Is data persistent on Neo4j?

[mikempc]

I've been using Neo4j in November but since then I had other things to do. Recently I relaunched the docker image and now all the data I had ... is gone ... Do you know A. if I can find it ? B. What could have lead to such a wipe out ? C. Is data persistent there ?

Here are my images:

Typically the graph persists outside the container for this very reason.
For example Introduction - Operations Manual

includes

docker run \
    --restart always \
    --publish=7474:7474 --publish=7687:7687 \
    --volume=$HOME/neo4j/data:/data \
    neo4j:4.4

where by the data volume is defined to persist outside of the container
