Create external backup of artfiles.de databases via phpMyAdmin panel behind DCP login.

dcpsqldump.sh

#!/usr/bin/env bash
# Script to backup an artfiles database via phpMyAdmin behind DCP.
# This is mainly useful for their "Private Web medium" plan because the
# next larger plan includes SSH access, so you can just use mysqldump directly.
# The exported SQL is piped to stdout and must be saved to a file or
# piped further for compression, encryption, etc.
# $ ./dcpsqldump.sh > database_$(date +%F).sql
