[pbs-devel] [PATCH proxmox-backup v1 1/1] close #3770: pbs-client: add quiet backup flag

[Hannes Laimer <h.laimer@proxmox.com>]

Signed-off-by: Hannes Laimer <h.laimer@proxmox.com>
---
this feels 'chunky', having quiet and verbose(which is sometimes called
debug). Maybe some kind general verbosity enum might make sense, but then
it should not just be used here.
