Database¶

Backups¶

Primary¶

The database is backed up every day at midnight. The dump file is located in /var/backups/postgres/.

Secondary¶

The whole virtual machine is backed up by BackupNinja on the "dom0" controller, using:
- rdiff backups every day
- tar files on Saturdays.

See /etc/backups.d on the dom0 (192.168.0.12).

Tertiary¶

TODO: remote backup.

Restoration¶

If the VM is not shutdown properly, there's a chance that the database is corrupt, and needs to be restored from one of the backups.

After the restoration, restart gisaf:

systemctl restart uwsgi.service

From primary backup¶

With user postgres:

# Optionally, rename the corrupt database, selecting another name than @avgis_c2@ every time:
psql -c "ALTER DATABASE avgis RENAME TO avgis_c2;" 
# Drop the existing database
psql -c "drop database avgis;" 
# Create a new database:
createdb -E utf8 -T template0 avgis
# Restore the database
pg_restore -d avgis /var/backups/postgres/avgis.pg_dump
