Method 1: Run the script on the backup server and pull the data from the server specfied by --ssh-source. This is usually the preferred way and prevents a hacked server from accesing the backup-data:
```
root@fs1:/home/psy# ./zfs_autobackup --ssh-source root@1.2.3.4 smartos01_fs1 fs1/zones/backup/zfsbackups/smartos01.server.com --verbose

After that you can rename the disk image from the temporary location to the location of a new SmartOS machine you've created.
Snapshotting example
====================
Sending huge snapshots cant be resumed when a connection is interrupted: Next time zfs_autobackup is started, the whole snapshot will be transferred again. For this reason you might want to have multiple small snapshots.
The --no-send option can be usefull for this. This way you can already create small snapshots every few hours:
````
[root@smartos2 ~]# zfs_autobackup --ssh-source root@smartos1 smartos1_freenas1 zones --verbose --ssh-cipher chacha20-poly1305@openssh.com --no-send
````
Later when our freenas1 server is ready we can use the same command without the --no-send at freenas1. At that point the server will receive all the small snapshots up to that point.
