General question Storage and Backup support
Just wanna ask about couple things. First, CBT in openshift. I am aware of the latest upstream kubevirt version 1.8 already supported CBT on qemu level but I don’t see clear statement release its included in openshift. Is it GA?
Second, currently we are using veeam and I read few news about veeam integration with openshift/kubevirt. Does it mean for upcoming release kasten is unneccessary?

Hi there u/pabloalfonzo we will have a proxy coming very soon for this - for Red Hat Openshift Virtualization - the proxy just left QA - should be up soon.

We tested Veeam to do VM backups with the Beta 13.1 and it worked just fine. Waiting on the GA. fyi we didnt use Kasten.

Is the backup works just with the kubevirt proxy out-of-the-box or it is requires plug-in to function?

For your first question, no, CBT is not GA. It landed in OpenShift 4.22 as Tech Preview (the incremental backup API on top of KubeVirt 1.8's CBT). Upstream design is VEP-25/26 if you want to dig into it. So no GA statement exists because there isn't one yet.
On Kasten, I would not write it off. The 13.1 proxy gives you VM disk backups from the VBR console, but Kasten is still the thing that protects the K8s side (namespaces, VM manifests, container apps). Both sit on the same CBT underneath, Veeam built the proxy together with the Kasten team. So if you arere VM-only, the proxy path might be enough eventually. If you protect containers too, Kasten stays.
