[pve-devel] [PATCH v2 guest-common] vzdump: correctly handle prune-backups option in commandline and cron config

[Fabian Ebner <f.ebner@proxmox.com>]

Previously only the hash reference was printed instead of the property string.
It's also necessary to parse the property string when reading the cron config.
