Adding to Jonathan's answer, I'd underline that in OI each zone's
root storage is a separate dataset heirarchy - which was recommended,
at least to have one dataset for the zone, but not enforced in other
OSes (Solaris 10, SXCE). Here the current roots (matching the GZ BE
related to package updates) are legacy-mounted into the zoneroot,
i.e. /export/zones/cupszone/root.

So to untar your zone's backup, you have to recreate a similar
structure, including a number of ZFS dataset attributes. Or make
a recursive zfs-send stream and transfer that.

HTH,
