since proxmox gui/scheduling won't allow serialization of this tasks,
i'm running them via cron/script

# proxmox-backup-manager verify pve-t620_backup --ignore-verified true
--outdated-after 30
# pvesm prune-backups pbs_pve-t620_backup --keep-daily 31 --keep-weekly
8 --keep-monthly 6
# proxmox-backup-manager garbage-collection start pve-t620_backup

regards
Roland
