Back in the olden days, I would just put a
mysqldump > dump.sql in a crontab and called it a day. When I started to host more and more stuff with docker, I first just migrated that approach to docker and put it all in a container. That still required me to mess around with config files. Once I started to host postgres containers it all got even more complicated. Thus, I needed a new solution.
I built this tool to make backups easy: Simply point it to a host running docker containers and it will automatically inspect and find all mysql/mariadb and postgres containers and do backups of them on a schedule. No configuration required, it “just works”.
