> Hi @rp- Can you perform some tests with this PR changes and confirm? I created a test cluster and also tested the backup nfs. Everything worked as expected, I only noticed that the backup .qcow2 file took the FULL space, so it looks like there is no zero discard happening. Is there a way to tell qemu/libvirt to use zero-discard while creating the backup image? Or would it be possible to later use `qemu-img convert -c` or `virt-sparsify` on the backup? btw. `virt-sparsify` only worked without using the `--in-place` option, but then the savings are huge 414M vs. 8GB, also the qemu-img compress gives 527M vs. 8GB.
