[Users] engine-backup restore how to

There doesn't seem to be any solid documentation on how to use the engine-backup restore function, and I'm not able to restore a backup. The best I've come up with is: 1. Install engine on new host 2. Stop engine 3. run engine-backup --mode=restore --file=filename --log=logfile Fail. Log shows: psql: FATAL: password authentication failed for user "engine" 2014-01-29 18:20:30 10285: FATAL: Can't connect to the database 4. engine-backup --mode=restore --file=engine.bak --log=logfile --change-db-credentials --db-host=localhost --db-user=engine --db-name=engine --db-password='newpassword' Fails with same error. 5. change user to postgres, drop the old db, create a new db named engine, set password for engine user same as 'newpassword' 6. engine-backup --mode=restore --file=engine.bak --log=logfile --change-db-credentials --db-host=localhost --db-user=engine --db-name=engine --db-password='newpassword' Restoring...
