Hi Tommaso, Thank you very much, it is really appreciated.
Currently, the incremental backup feature is in its final stage of development. We have a few issues in the underline layers (libvirt \ QEMU) that prevent us from preforming some flows but we expect them to solve in the first RHEL 8.2 Z-stream. The first stage of incremental backup for a running VM will be available in oVirt 4.4 GA as a tech-preview. You will be able to perform an incremental backup for a running VM (when the VM will go down you will need to take a full backup again). All the API is already implemented so you will be able to start and build your backup solution. Here is a short demo of the first incremental backup in oVirt - https://youtu.be/CWKqapnvntg Thanks, On Thu, 23 Apr 2020 at 11:39, Tommaso - Shellrent <tomm...@shellrent.com> wrote: > Hi Nil, my colleague Francesco and I are very interested in incremental > backups. > Is there an estimate of the release date of the feature? > Can we somehow collaborate with you to speed up its development? > Il 20/04/20 21:15, Nir Soffer ha scritto: > > On Mon, Apr 20, 2020 at 3:39 PM Eyal Shenitzky <eshen...@redhat.com> > <eshen...@redhat.com> wrote: > > Hi Francesco, > > It is great to hear that you are trying the new incremental backup feature. > First, please note that in this stage we implemented only the support for > full VM backup. > > In order to use it, you need libvirt version 6.0 at least. > > The only upstream distro that can be used now is Fedora 30.
