Until a few months ago I was using Qemu/KVM/VirtManager with snapshots
for linux and Windows VM's running network services - the trick is
redundancy and suspend.

Using libvirt, suspend the VM which copies ram to disk, then snapshot
((I used btrfs) both the ram and storage and restart the VM - takes
seconds (so redundancy may be needed) - at this point I backup'ed the
snapshot and deleted it.


When using snapshots of live systems, I had problems restoring some of
the more active VM's which this avoids.
