Currently there's no such integrated tool, but honestly I do not think that
would be *that* hard to make. We have a similar process in plan for VMs, i.e.,
boot a VM with a live system and the backup disks as read only disks
plugged in.

Note also that the client has already support to mount an archive of a backup
locally over a FUSE filesystem implementation - maybe that would help already.

Yes.

So here I do not have all details in mind but AFAIK: mot yet, it detects
some file changes where inconsistencies could have happened but doesn't
yet tries to detect if the underlying storage supports snapshots and uses
that to get a more consistent state. For containers we do that explicit
through the vzdump tooling.

No, currently I do not have any, I'm afraid.

Great, hope it fits your use case(s).
