Redeploy local vpn version

Since I am open sourcing it, I'll be moving away from hosting a public cloud version for users.

Instead, I need to create a local production host for myself and a public demo version.

A few things needed for this:

[ ] a script to backup data for a user from couchdb to a file
[ ] a script to load that data into a couchdb
[ ] a script to compare two sets of data in two different couchdbs to validate a copy/backup
[ ] a backup of the prod db, both using my script and at a filesystem snapshot level
