I've read that NDMP was provided in OpenSolaris and is an "open"
protocol to handle backups in an interoperable manner. Possibly
it can wrap ZFS backups even if they need to be split over many
tapes. I have no experience with it and haven't read more, so
can't really elaborate or even say if it is what might help you.

Cursory googling came up with a couple of interesting articles:
