[PVE-User] Is it possible to use qemu Livebackup feature withProxmox?

["[SOLTECSIS] Carles Xavier Munyoz Baldó"]

Ok, I understand then that it is a problem of backup time (because it
reads all blocks), but the resulting incremental its ok, isn't it?

It is better to really read only the changed block since the last
backup, it will be possible when the qemu incremental backup is
commited, but in the meantime I believe that something like de Ayufan's
patch integrated in the Proxmox official release will be great.

What do you thing about it?
