A backup container dumps the database every night, keeps 14 daily and 8 weekly
copies and once a week restores a copy into a scratch database to check tables
and row counts. update.sh takes a copy before updating, restore.sh brings one
back and keeps the old database aside. CI runs the dump, verify and restore
cycle on the database the end-to-end journey filled.
