I’m sort of new to Dreamcompute and all its terminology and concepts, despite having used it (successfully!) for a couple years. What I want to do now is a dist upgrade from Debian 9 to 10 on a server instance. Debian’s official instructions include solemn warnings about the need to back up, so I am looking for how to do that as painlessly as possible.
I see how to create an image/snapshot from one of my instances – easy enough. Now suppose I shoot myself in the foot and want to restore that instance from the snapshot. I haven’t been able to find documentation about that.
I can imagine you could create a new instance from the snapshot, yes. But it would have a unique name – i.e., different from the one I want to roll back to its earlier state. True? I am looking for a way to restore the same instance back to its former state, including its IP addresses and all that good stuff.
Any thoughts? Is there a tutorial somewhere that covers this?
