Backup your machines on Pfsense with znapzend tool.

<!--more-->

### The servers
```
proxmox-node1 192.168.10.20
omv-nas1 192.168.10.50
```

### Create sub volume
Note that while recursive configurations are well supported to set up backup and retention policies for a whole dataset subtree under the dataset to which you have applied explicit configuration, at this time pruning of such trees ("I want every dataset under var except var/tmp") is not supported.

```
zfs create local-zfs/vm-data
pvesm add zfspool local-zfs --pool local-zfs/vm-data
```

### Build znapzend on servers
```
apt-get install perl unzip git mbuffer build-essential git
