Hi Martin, Keep in mind this is a single host.. so.. is there a command line operation I can run from the host to snapshot the running engine VM? Then if then update fails I can revert (by command line) the running VM from before the update. I don't mind getting my fingers dirty if I have to script it.
I've used the "engine-backup" tool, but frankly IMHO a snapshot is a better way to handle an immediate update, rather than having to completely re-install the VM and restore from backup. This operation is exactly why snapshots exist. :) Thanks, -derek On Fri, November 18, 2016 3:33 am, Martin Sivak wrote: > Hi Derek, > > I do not think we support snapshots of the hosted engine VM at the > moment.
