When you have a service which is acting weirdly, ideally I'd like to snapshot the VM, then do whatever I need to do to repair the service urgently.
That might involve making a new VM from scratch, but it also might twiddling some settings, or other emergency changes.
Afterwards, I want to be able to restore the VM state, probably in a firewalled off environment, so I can debug exactly what was wrong.
Sometimes I'd like to do it to a set of VM's - for example, if there is some DNS wierdness, I might want to snapshot an application server and a DNS server.
So far, no cloud provider seems to offer functionality to make that easy, which is a bit disappointing.
