[libvirt-users] Drive-backup functions.

List, Two years ago there was discussion on implementing QEMU's block-dirty-bitmap backup solution: https://www.redhat.com/archives/libvir-list/2016-June/msg00380.html https://www.redhat.com/archives/libvir-list/2016-April/msg00401.html But I haven't seen anything since, and looking through git, it doesn't look like any of these patches were included. Can someone please bring me up to speed on what is up with these patches and what the current thinking is in regards to backing up with libvirt? Currently I'm snapshotting, then syncing the quiesced base image to one I have on alternate media, but it's slow and takes up a lot of space. Thanks, schu
