mike Right now the best way to manage this is to use Borgbackup or something similar like Restic, that can make a true byte level backup of the data, without having to shutdown the system and make a traditional image. That backup can then be stored wherever you wish, another country, another provider etc... The problem is it's complicated and manual setup. Which isn't as easy to manage.
The CP replication will allow for failover to another server already in the cluster and likely with a different provider and /or certainly in a completely different DC. Super useful if your growing your estate or find a crap provider and need to move.
Currently the CP can be moved, once you've moved it and start it up with it's new IP, it will ASSUME that IP and then talk to all nodes as that IP (from what I've learnt) But if you move a server over to another box and bring it up to TEST, you'll inadvertently send that signal out, even if the image has a bad issues and is no good. So for now I don't trust this process to be straightforward, it's doable at best if needed.
Likewise in the event of complete DR, the CP database is backed up as well by enhance backups, enhance could help. But that's no DR at all and very bad business practise and if your estate was massive, well I dread to think how long it would take to manually recover.
DracoBlue Yeah I am figuring it will be at least a few more months. I remain optimistic.
