I plan to backup to another drive on the same disk.

I downloaded the July 10th build of the REST standalone server and created a
neo4j.properties file
with enable_remote_shell set to true. However, when I try to connect it, I
still
get the locked
store message and it prompts me to open as readonly. Do I also need something
in
the
wrapper.conf file? Also, used JConsole to see the configuration attributes
which
show up as unavailable.
