Hello & greetings.
as a "newbee" in Unix / Linux system and also Proxmox I'm looking for some help please...
I have HomeAssistant (VM), EMQX and Zigbee2MQTT as LXC still running fine on my Proxmox - without any issues or problems.
Since a couple of days I receive a error: "bad message (74) about my automated backup to my QNAP NAS of only the Zigbee2MQTT LXC (complete log file attached).
The HA VM and EMQX LXC backups are without error.
I would be very pleased if anybody can give me a hint and helpful hand
how to fix this issue.
Kind regards, Alex
