AFAIUI, morebots has been completely replaced by Stashbot now and is no longer needed (please confirm). The easiest way to archive it would be to tar the whole directory, but:
tools.morebots@tools-bastion-03:~$ du -hs * 40K cache 72K confs 4,0K IRCNOTIFIER_KEY 4,0K labs.sh 4,0K logs 4,0K production.sh 4,0K public_html 4,0K qa-morebots.sh 4,0K README 4,0K replica.my.cnf 1,1M src 4,0K STASHBOT-DOES-THE-WORK-NOW 212K test-adminbot 4,0K test.py 19M venv tools.morebots@tools-bastion-03:~$
shows that the majority of the space is occupied by a venv and the source that is already archived in Git, so if the configuration files are no longer deemed important, I think just deleting the directory would work as well.
