Limitations

This article presents limitations of the Proxmox Plugin.

Granular restore (Single Item Restore) is not available yet. A file level backup of the VM with the Bacula FD inside the Guest VM is needed to enable single file restores of a Proxmox guest VM. Read more here.
Concurrent backups of the same guest VM are not possible.
Only Full level backups are possible. This is a Proxmox limitation as its API does not provide methods suitable for other backup levels. This limitation is described in details in the Features chapter, which also describes another module, QEMU that is free of that limitation.
VM templates available on the Proxmox system can not be backed up. This is also a Proxmox limitation.
In listing mode with the vm or vmid parameters, the plugin will display both guest VMs and VM templates. This limitation will be removed in the future.
Backup of LXC created in unprivileged mode could fail with Permission denied error in Proxmox Task execution log and a following job messages error log:
```
Error: proxmox: Error closing backend. Err=Unknown error during program execvp
```
This is a known issue which will be removed in future release of the plugin.
The restart command has limitations with plugins, as it initiates the Job from scratch rather than continuing it. Bacula determines whether a Job is restarted or continued, but using the restart command will result in a new Job.
