Troubleshooting

If you encounter a following error during backup job:

Fatal error: proxmox: Error closing backend. Err=Unknown error during program execvp

You should check the Proxmox Task log for the following error:

TASK ERROR: could not get storage information for 'local':
       can't use storage 'local' for backups - wrong content type

Then your ’local’ Proxmox storage resource is missing the required ’backup’ content type. This kind of configuration is expected by vzdump Proxmox command to save a backup task log and guest vm configuration. As a remedy you can add a missing ’backup’ content type to the ’local’ Proxmox storage resource or configure your backup job to use a different Proxmox storage resource for that. In the latter case you should add a vzdump_storage=... parameter to your configuration.
