It'd be handy for wiki sysops to be able to backup their wiki any time they choose (e.g. when there has been major changes) rather than having to wait until the next scheduled backup dump, which could be a week away. The easy way to do this is with the WikiTeam's dumpgenerator.py script.
However running this on a Miraheze wiki
python dumpgenerator.py --api=https://mywiki.miraheze.org/w/api.php --xml --images
gives the error: "Error in index.php, please, provide a correct path to index.php"
