does KVM in CentOS have native virtualization 'drivers' for Win2008
server? if not, I wouldn't run it in a production environment.
I wouldn't use Vmware Server/Workstation for a production server,
either. I found VMWare server 2.x quite unstable on a number of
different configurations, and the performance is considerably lower than
the native hypervisor style virtualization like ESX(i)
VMWare ESX(i), assuming your hardware is supported, works great. Rock
solid, very good performance, excellent support for windows, linux,
solaris, etc guests. VMware supports copy-on-write snapshots, too.
re backups, you do know Windows Server has its own snapshot feature for
taking backups, known as VSS (Volume Snapshot Services) ?
do note, snapshots are an AID to backups, they aren't a substitute for
proper offsite archived backups for emergency recovery. For instance,
they won't protect against system hardware failure. Any, a volume with
too many snapshots pending tends to bog down considerably in disk IO
performance.
