# Creates backups/world-YYYY-MM-DD-HHMM[-label].tar.gz and uploads it

# as a Gitea release asset on the `origin` remote.

# If the container is running, flushes world via rcon and archives via

# docker exec. Otherwise archives data/world from the host directly.

# the local archive is still created and upload is skipped.
