openQRM consist of "files" and a "database". Having a backup of both parts allow to "roll-back" the update at any point.
All files in openQRM are located within the openQRM base-directory (normally /usr/share/openqrm). To create a simply backup please run the following commands as 'root' on your openQRM Server:
cp -aR /usr/share/openqrm /usr/share/openqrm-5.0.before-update
To backup the openQRM database content (assuming mysql as the database backend) please run:
mysqldump openqrm -p > /usr/share/openqrm-5.0.before-update/openqrm-db.sql
This command will ask for the openQRM database password.
At any time you can roll-back to your previous state of your openQRM environment by running as 'root'
mv /usr/share/openqrm /usr/share/openqrm-update-rolled-back && mv /usr/share/openqrm-5.0.before-update /usr/share/openqrm && /etc/init.d/openqrm restart
Furthermore openQRM provides a 'state-backup' which captures the full-state (all configuration files and the databases content). A 'state-backup' of openQRM also allows to "roll-back" the update at any point. To run a state backup please run:
/usr/share/openqrm/bin/openqrm state backup -n 5.0.before-update
To list all state backups please run:
/usr/share/openqrm/bin/openqrm state list
To apply/restore a state backups please run e.g.:
/usr/share/openqrm/bin/openqrm state restore -n [backup-name]
