Allow selecting namespaces to backup on a NS label instead of the NS names

[titou10titou10]

velero backup createallows to backup:

• all resources from namespaces included by their names:--include-namespaces
• resources that match a certain label :--selector (possibly more restricted by the--include-namespaces above)

What we need is to backup everything belonging to namespaces that have specifically a certain label attached, ie select the namespaces to backup based on an label assigned directly to the namespace, instead of their names

Is there a way to do this?

If not, it would be something like adding a new parameter for this: --include-namespaces-selector?
Thx

@titou10titou10 unfortunately Velero does not currently support this.

We do already have a feature request for this in the backlog - see #503. I'm going to close that one out and leave this one open for tracking.

Are you interested in working on a contribution here? If so, we can discuss more on what the design for this would look like.

Having a namespace label selector for all the objects in that namespace, would be a great improvement usage of Velero.

Closing because will be handled when #2413 is implemented.
