Hello Anselm,

Thanks for your help.

The final purpose is to backup and restore SOGo from scratch, so maybe
I will end up restoring the whole database.

Nothing in the method above seems appropriate for me.

Since I want to do the backup on the local machine, http or https is
not very relevant. What is more, however, is that I need some "special"
account, with read access to all user's address books and calendars,
and I did not find anything close to this in the documentation.
