100% agreed. Unfortunately VMware doesn't allow to take snapshots of powered off virtual machines. I'd really like to see that as a means to minimize downtime: shutdown take snapshot boot (downtime less than 5 minutes) now take all the time you need to copy/backup snapshot while your virtual server ist already back at your service Does anyone know the reason why you cannot snapshot powered off machines?
