There is a cronjob which runs to backup the omero db and this cron job is normally set to run on a nightly basis at ~2am.

Columbus stores the resultant backup file (pg_dump file) in /OMERO/OMERO4_4/db_backup

The dump files are updated nightly with a maximum of 3 pg_dump files being retained.

It is possible to backup the omero db manually by using the pg_dump utility. The arguments specified in the command dictate how the dump is created. More information regarding pg_dump can be found on the following webpage:

Manually create a db dump (log in as the 'columbus' user):

$ pg_dump -Fc -v -f /OMERO/OMERO4_4/db_backup/omero4_4_backup.pg_dump omero4_4

Restore the db dump:

$ sudo /etc/init.d/columbus stop

$ pg_restore -v -c -Fc -d omero4_4 /OMERO/OMERO4_4/db_backup/omero4_4_backup.pg_dump

$ sudo /etc/init.d/columbus start
