Fri Feb 26 04:07:51 PST 2016

Dear all,
as a follow up on this you can find here

https://github.com/GeoNode/geonode/commit/cf1c7e7c7a90239f5171a6f83608d4d40360c262

The GeoNode backup and restore utilities converted into GeoNode Base
Management Commands.

They can be invoked now as:

*python manage.py backup --backup-dir=/tmp/*

*python manage.py restore --backup-file=/tmp/2016-02-26_054445.zip*

Best Regards,
Alessio Fabiani.
