Backup/Migration: Which mailu folders hold relevant data?

[sando38]

Hello friends,

I have the following directory holding all mailu related data:

root@mailu-1-3db6-120e92:/home/mailu# ls
certs  dav   docker-compose.yml  hack  mailu.env  pass   webmail
data   dkim  filter              mail  mailqueue  overrides  redis

Your documentation mentions backups/migrations, etc. could be done via rsync, etc.

Which folders should be backed up?

Thanks in advance and have a great day!
