Yes, this is no different, really. It would work very well. Just keep it
in sync, and all should be fine. You can just pull out any drive at
will, without causing any filesystem corruption. The fireproof drive can
be inserted in a different computer with ZFS support and you can run
"zpool import" and then you can mount the filesystem.

You shouldn't use USB for your external drive, though. E-SATA, Firewire
or Thunnderbolt is fine.

I don't mean to say RTFM, but the top results of a Google search are as
good a starting point as any:

I think this article is quite good:

If you have any further questions, don't hesitate to ask. :)
