Should one reinstall a freedombox from the beginning, setup domain and users exactly as they were before (I noticed the documentation says they are not saved), upgrade and then restore?
Is something else missing before doing the restore? Or is the order different?
Is there another way to use the restore function?
Is it possible to restore while using a different domain?
With respect to email:
provided the user accounts are configured before restoring, will all aliases be restored as well?
are previously received email restored as well in dovecot?
I configured my routeur so that it allocates the IP of my old freedombox to the new hardware (so I don’t have to change all the rules and my SNI proxy configuration)
after booting a fresh install, I connected to plinth, setup the admin username/password, said how the freedombox is connected to internet, waited for software update to complete
I did the restore (it requires creating the archive to restore, which needs running “borg export-tar” on the machine where the backup is), this puts the applications back
I recreated all the users
I configured the domain and ask Let’s encrypt to renew certificates
I added a fresh remote backup location and activated scheduled backups
Then I see that the emails are there. I did not try changing the domain.
My conclusion: it works well but the manual is missing the information how to restore the backup.
EDIT: changed “backup” to “software update” in 2., I was obsessed with backup obviously.
