I am getting the strong feeling that if I want to get my ideal, I will have to switch to a service that does give me full VMware control and thus the snapshotting control. Currently my provider does a one-size-fits-all, weekly snapshot for the most recent 4 weeks, and making a restore request goes to their sysadmin ticketing system and takes days and days. :-(
I doubt this has anything to do with VMWare. SimFS and unable to load Kernel Modules looks more like Linux container like OpenVZ/Virtuozzo. With this you only have userland for your backup.
