Offline Backups with two (or more) External Disks
-------------------------------------------------
It can be desirable to have multiple disk-based backups of the same machine.
To accomplish this,
* create one zpool per external HDD, each with a unique name, and
* define a pair of ``push`` and ``sink`` job **for each** of these zpools, each with a unique ``name``, ``listener_name``, and ``root_fs``.
The unique names ensure that the jobs don't step on each others' toes when managing :ref:`zrepl's ZFS abstractions <zrepl-zfs-abstractions>` .
