I am running a debian server on a KVM/qemu
machine. we are using overlays (1 to max 3 levels) when testing
new things and commit them back to base when tests where good.|
Now I accidentally saw that qcow2 (or maybe qemu in general)
aswell allows snapshots and I wonder what the difference between
the mechanics of those 2 is.
Can someone kindly explain that? Furthermore I
know that in vmware some people use snapshots for backup purposes and wonder whether that
would be a concept wioth qemu snapshots as well.
