Below I describe the backup procedure taken from: http://docs.geonode.org/en/latest/deploy/backup.html

For migrating from one GeoNode version to another, in particular 1.2 to 2.0 check this document: http://docs.geonode.org/en/latest/tutorials/admin/migrate/index.html#migrate

For moving to another server, the general advise is:

• backup GeoNode - Django project + DB, backup GeoServer (DataDirectory)
• update/upgrade the current server to the latest version
• create a new server + move all the project files
• see this link for a GeoNode style template: http://github.com/GeoNode/geonode-project

Backup GeoNode Server (with GeoNode 2.0c8):

1. Backup Geonode users DB (psql needs to be running)
   • sudo -u postgres -i pg_dump -c -Fc geonode > /home/ssteinig/geonodedb.backup
2. Stop services
   • sudo service apache2 stop
   • sudo service tomcat7 stop
   • sudo postgresql-8.4 stop o: sudo service postgresql stop
     (I am actually running PSQL 9.1.11 on cedeusgis1)
3. Backup Geonode config & GeoServer data directory:
   • sudo tar -cvzf /home/ssteinig/geonodeConfigBackup.tgz /etc/geonode
     Note, doing this step for backup is good, but when archiving for moving to a different server, it is better to edit the important local_settings.py file manually.
   • sudo tar -cvzf /home/ssteinig/geonodeDataBackup.tgz /var/lib/geoserver/geonode-data/
     Note, this step my not be very useful as the GeoServer data seems to be in a different folder (see next step). Hence, geonodeDataBackup.tgz may be empty and...
   • it looks like GeoServer data are here: /usr/share/geoserver/data/ . So we shall make a backup of it too:
     • sudo tar -cvzf /home/ssteinig/geoserverDataBackup.tgz /usr/share/geoserver/data/
4. In addition, any templates, design changes, uploaded documents, and CSS files will also need to be captured.
   • e.g. my modified css and logo have been in /etc/geonode/media/geonode/img/ ... so they should be backed-up within the config tgz file.
   • but my text modifications to the start pages (i18n strings) are in a different location (...but see as well below where I save the whole Django GeoNode package)
     • sudo tar -cvzf /home/ssteinig/geonodei18nBackup.tgz /usr/local/lib/python2.7/dist-packages/geonode/locale/
   • just to be save I may also do a backup of the GeoNode web folder where I have the CSS, the thumbnails, and uploaded documents (pdf + xls +doc, etc):
     • sudo tar -cvzf /home/ssteinig/geonodeWWWBackup.tgz /var/www/geonode/
   • and a copy of the Django GeoNode folder and the egg-info folder that I needed later:
     • sudo tar -cvzf /home/ssteinig/geonodePyDjangoBackup.tgz /usr/local/lib/python2.7/dist-packages/geonode/
     • sudo tar -cvzf /home/ssteinig/geonodePyDjangoEggBackup.tgz /usr/local/lib/python2.7/dist-packages/GeoNode-2.0-py2.7.egg-info/
5. re-start the previously stopped services: Apache2, Tomcat7, PSQL

Backup Spatial Data DB

Restore GeoNode Server

copied text - not tested yet

1. stop all services: apache2, tomcat7, psql
2. restore GeoNode config and GeoServer
   • sudo tar -C / -xvzf /home/ssteinig/geonodeConfigBackup.tgz
     Note it may actually best to not do this step, but to manually edit local_settings.py. The logo image that is currently in that archive is also not super important and gets placed in it position when I restore from geonodeWWWBackup.tgz that contains /var/www/geonode.
   • sudo tar -C / -xvzf /home/ssteinig/geonodeDataBackup.tgz
     This step may also not be very useful, as the file does not contain any data since the folder /var/lib/geoserver/geonode-data/ is empty. However, GeoServer data seems to be /usr/share/geoserver/data/ instead)
   • when moving to a different server, I did re-run now:
     • sudo geonode-updateip 10.0.2.15 to get the same db settings
     • modify the file local_settings.py
       • change the geonode db password to the one from the new machine
       • set the Allowed_Hosts variable to "*"
     • sudo geonode collectstatic -v0 to copy the styles/logo into /var/www/geonode/static/geonode
3. restore the template and design files
   • restore the static web page part
     • sudo tar -C / -xvzf /home/ssteinig/geonodeWWWBackup.tgz
   • when moving to another server with a different GeoNoder version (2.0 final instead of 2.0c8), then I got a DB error, ala: "DatabaseError at / [...] <column base_resourcebase.license_id does not exist [...] LINE 1: ...ype_id", "base_resourcebase"."constraints_other", "base_reso... " with the location /usr/local/lib/python2.7/dist-packages/geonode/search/views.py in search_api, line 160
   • hence, I deleted the django folders of GeoNode 2.0 final:
     • /usr/local/lib/python2.7/dist-packages/geonode/ and
     • sudo rm /usr/local/lib/python2.7/dist-packages/GeoNode-2.0.egg-info/
   • and restored the whole django-geonode package backup-ed from 2.0c8 before using
     • sudo tar -C / -xvzf /home/ssteinig/geonodePyDjangoBackup.tgz
     • sudo tar -C / -xvzf /home/ssteinig/geonodePyDjangoEggBackup.tgz
     • This will also restore my i18n strings, i.e. the text on the GeoNode startpage.
4. Restore the GeoNode database
   • sudo service postgresql start (or: sudo /etc/init.d/postgresql-8.4 start)
   • sudo -u postgres psql
   • drop database geonode;
   • create database geonode;
   • \q
   • sudo -u postgres -i pg_restore -Fc -d geonode /home/ssteinig/geonodedb.backup
5. When switching Server to a new GeoNode version, then the problem is that the new GeoServer does not know the data yet. Hence, if I want to display a layer in GeoExplorer, then nothing is show. Looking into GeoServer, there are also no layers. So the data need to be updated from the db. For that I use
   • geonode syncdb --noinput --all
6. start services: apache2, tomcat7

Restore DB
