I want to install some packages on a production instance, needed for a new application to work. But I'm afraid of some conflict with the applications already running. In VMWare vSphere I usually make a clone of the VM, and I change the VM to Clone in case it fails. From what I've been seeing, in Oracle Cloud it seems to be more complicated.
As I understand it here, I have to backup the boot volume of the instance, then do the restore, then create a new instance and attach the boot volume as an image. Then I have to leave the same network settings, copy and paste the ssh key that connected to the old instance, among other things, perhaps.
I found it more complicated. But sometimes you know of a simpler way to restore an instance to a healthy point.
