[pbs-devel] [RFC proxmox-backup] fix #5710: api: backup: stat known chunks during backup

[Dietmar Maurer]

> For this case, the index is initially copied over from the previous

No, sorry. But Gabriel pointed out that this will have a negligible effect in most cases, so we can keep the current code if too difficult to implement.
