-It is running a crontab that execute the backup.sh script every day at midnight.
-
-The dump of the database are stored in folders name like this : "ecolyo-agent-YEAR-MONTH-DAY-HOUR-MINUTE-SECOND". Only the 14 last days are stored.
-
-The location of the backup folder on the server is specified in the volumes of the "database-backup" service, in the docker-compose file.
+Backups are scheduled automatically with the help of CronJobs on Openshift.

+- Monter un pod du déploiement "database-restore"
+- Rentrer dans le terminal de ce pod
+- Aller dans le dossier des dumps horaires `cd /dump/hourly` ou journaliers `cd /dump/hourly` ou hebdomadaires `cd /dump/weekly`
+- Décompresser le dump souhaité `gzip -d YYYY-MM-dd_hh:mm:ss.sql.gz`
+- Restorer ce dump (remplacer seulement YYYY-MM-dd_hh:mm:ss.sql) `mysql -uroot -p$MYSQL_ROOT_PASSWORD -h$DATABASE_HOST $MYSQL_DATABASE < YYYY-MM-dd_hh:mm:ss.sql`
