Hello Stefan,
Can you expand on this some more? I have similar concerns for Livebackup.
At the beginning of your paragraph, did you mean 'asynchronous I/O
emulation' instead of 'synchronous I/O emulation'?
Also, I don't understand the 'stack' construct that you refer to. When you
say 'push a

Hello Stefan,
I have been thinking about this since you sent out this message.
A quick look at the libvirt API indicates that their notion of a
snapshot often refers to a "disk+memory snapshot". It would
be good to provide feedback to the libvirt developers to make
sure that proper support for a

than vmware, xen and hyper-v.
Thanks,

Hello Dor,
Let me see if I understand live snapshot correctly:
If I want to configure a VM for daily backup, then I would do
the following:
- Create a snapshot s1. s0 is marked read-only.
- Do a full backup of s0 on day 0.
- On day 1, I would create a new snapshot s2, then
copy over the snapsho
Hello Dor,
One important advantage of live snapshot over live backup is support of
multiple (consecutive) live snapshots while there can be only a single
live backup at one time.
This is why I tend to think that although live backup carry some benefit
(no merge required), the live snapshot + liv
