Backup script for Lemmy - eviltoast

Hello, do you know about a script or app or so that can backup data from a Lemmy instance as an end-user? At least the list of subscribed communities, settings, profile (bio) should be nice. I’ve been on VLemmy and lost one full evening trying to figure out what my subscription were (well not completely lost my time I also discovered new communities), but I want to avoid that in the future. If this doesn’t exist yet I may develop it but I’m pretty sure I’m not alone and someone did it already…
