Usage
=====
Example usage
=============
In this example we're going to backup a SmartOS machine called `smartos01` to our fileserver called `fs1`.
Its important to choose a uniq and consistent backup name. In this case we name our backup: `smartos01_fs1`.
Select filesystems to backup
----------------------------
On the source zfs system set the ```autobackup:name``` zfs property.
For example, to backup a complete smartos host:
```
[root@smartos01 ~]# zfs get -t filesystem autobackup:smartos01_fs1
NAME PROPERTY VALUE SOURCE
zones autobackup:smartos01_fs1 true local
zones/1eb33958-72c1-11e4-af42-ff0790f603dd autobackup:smartos01_fs1 true inherited from zones
zones/3c71a6cd-6857-407c-880c-09225ce4208e autobackup:smartos01_fs1 true inherited from zones
zones/3c905e49-81c0-4a5a-91c3-fc7996f97d47 autobackup:smartos01_fs1 true inherited from zones
```
