[pbs-devel] [PATCH v2 proxmox-backup] fix #3323: dry-run for cli backup subcommand

Fri Feb 18 10:55:38 CET 2022
From: Markus Frank <m.frank at proxmox.com>
adds a dry-run parameter for "proxmox-backup-client backup".
With this parameter on it simply prints out what would be uploaded,
instead of uploading it.
