If you wish to create backups of your BitBot instance (which you should, [borgbackup](https://borgbackup.readthedocs.io/en/stable/) is a good option), I advise backing up the entirety of `~/.bitbot` - where BitBot by-default keeps config files, database files and rotated log files.
I run BitBot as-a-service on most popular networks (willing to add more networks!) and offer github/gitea/gitlab webhook to IRC notifications for free to FOSS projects. Contact me for more information!
