[k8s] Ability to backup all volumes

[Arno500]

Currently the driver expects a specific PVC name and namespace. This is cool, but I guess a really common use case would be to back up everything (or with the labels filter), notably in the case of a self-hosted home Kubernetes cluster such as metadata backups for k8s:// which will backup everything at once if requested.

It just gives:

arno@serveur ~ [1]> plakar at @somewhere backup k8s+pvc://
[00:00] 00000000                                                                                                                                                                                                                                                                                                                                                                     0 B
        import: nodes=0, objects=0
         store: read=0 B, write=0 B
plakar: failed to create an importer for k8s+pvc://: bad location: expected namespace/pvc-name but got

If I had to guess, the k8s+csi have the same issue.

Thanks a lot!

Hello,

Yes, k8s+pvc and k8s+csi work on a pvc-by-pvc basis. The rationale was that, in my experience, you usually don't want to back up all the PVCs in a cluster, so I went with the more granular way.

Now, I do understand though that there are situations where just doing a backup of everything (maybe still filtering by namespace and/or labels) is desiderable.

I'll discuss this internally (need to see which is the best way of doing this bulk import) and will get back to you.

Thanks!
