Is the computer powerful enough to run windows in a VM? If so, do that on a snapshot-capable filesystem (zfs or btrfs) and run a nightly cron job to snapshot the windows VM, and keep old snapshots for at least a month. If he gets scammed again, roll back to the night before.
My understanding is that COW file-systems such as ZFS or BTRFS are horrible for VMs, and recommended practise is to turn off COW.
COW within COW is bad, so don't use BTRFS for the filesystem inside a VM and for the VM data store. Running Ext4 in a VM and BTRFS or ZFS for the VM store works well enough as long as your disk access isn't too intensive. If you use SSD for the storage then performance should be fine. The LUV server is running on a ext4 filesystem in a KVM VM on top of a BTRFS RAID-1 (with snapshot backups) on a pair of SATA SSDs. It works OK.
How does Windows licensing work such a system? Do you need to purchase another Windows license to use it within a VM?
Legally if you have one Windows OS and one Windows license it should be OK but MS might try to stop that with some license terms. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
