VM/Container Backup

Proxmox VE backup failed with connection error

Problem

  • Proxmox VE backup failed with Error connecting to proxmox System: "('Connection aborted.', gaierror(-2, 'Name or service not known'))"]. This error occurs after a VM was migrated to another cluster node. Consequently, the Proxmox VE backup fails.

⇒ Solution

  • Ensure that every Proxmox VE cluster node can resolve other cluster nodes correctly by using DNS or hosts file.

File backup of Proxmox hypervisor fails

Problem

  • Backup of /etc/pve/ fails.

⇒ Solution

  • You should exclude the /etc/pve/ directory from backup; /etc/pve/ is only a file system representation of the cluster database, which is located at the path /var/lib/pve-cluster/config.db. For more information, see Proxmox wiki article. For further information also see Proxmox Cluster File System (pmxcfs).
