I was struggling with disk space issue on the server hosting my Mastodon instance. I thought Mastodon was eating all disk space... I was #wrong! The space was used by a forgotten backup (~50G) and older docker stuff (~50G).
rm backup and docker system prune and docker images prune -a did the trick.
Disk space went from 160G to 44G. Yay!
