Start/stop DBMS from cypher-shell? (Community Edition 4.4.3 on Mac)

I thought I might script a shutdown-dump-startup sequence to back up my local working DB daily or so. It seems that neo4j-admin isn't fully supported on CE, but cypher-shell seems to have some commands that should help.

I tried "stop database neo4j;" and it did indeed stop. But then "start database neo4j;" has no effect. It gives an error message about the database being "unavailable".

Worse, the DB seems corrupted. Neo4j Desktop can start it, but then the Browser shows 0 nodes.

So... is there a known issue with "stop database" being dangerous? Or am I missing the documentation of the correct sequence of operations?
