I have searched around but could not really find an answer to my question. My intended set-up is:
UCS Master as home server reachable from the internet via dyndns with (among others) installation of Nextcloud.
UCS Backup or Slave on a hosted (low price, low performance) vserver with installation of Kopano.
The idea is to have all my Nextcloud data at home and use the high availability of a hosted system for receival of emails. I simply don’t trust the reliability of our local ISP and the stability of my homebrew hardware, which is okay for nextcloud, but not for email.
Will this setup work, especially having a UCS Master whose ip is changing over time? How will the UCS Backup/Slave get to know the updated Master IP? I could not really find an answer to this in the docs or the forum
Thanks for you support!
