DEICH-5666 croncile: backup and restore routine

cronicle/README.md

+# Cronicle
+
+Cronicle is a scheduler for all the periodic jobs that the various components in the system needs to run. This includes backup of databases, and all the different tasks that Koha must perform routinely.
+
+## Backup and restore of Cronicle configuration data
+
+A cronicle-job is set up to take a daily backup of Cronicles configuration. This includes all the jobs and the shcedule, but does not include the output of the historical job runs.
+
+The backup is just a single text file, and is stored in the same place as MariaDB and Virtuoso backups are stored.
+
+To perform a restore, the backuped file must be put in to the mounted data volume at a designated location, so that cronicle will import it on next restart of the container.
+
+To fetch the latest cronicle backup and restore config run the following (se deployment-config repo for environment variables):
+
+```
+> docker stop cronicle # cronicle MUST be stopped before restore
+> docker run --rm --network bridge -v ${SSH_PRIVATE_KEY_MOUNT}:ro -v ${SSH_PUBLIC_KEY_MOUNT}:ro -v deichman_cronic
+le_data:/cronicle-data instrumentisto/rsync-ssh rsync -e "ssh -o StrictHostKeyChecking=no" -azPv --delete --progress
+--info=progress2 --copy-unsafe-links datafetch@${DATAFETCH_HOST}:$backup_dir /cronicle-data/restore
+> docker start cronicle
+```
