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

["[SOLTECSIS] Carles Xavier Munyoz Baldó"]

Yes, but it is possible to make a local incremental backup and then
rsync it to the remote datacenter. It requires a lot of less bandwidth
than if we have to transfer full backups every day to the remote data
center.

I understand that Ayufan's patch is not the best option for incremental
backups but I believe that, if there is no backup inconsistent data
problem with it, is a good option until exists something better.

What do you thing about it?
