So you zfs send to a file and save the file to tape?

Personally, I use zfs send and zfs receive to replicate the data to
a second system, and then simply tar the replicated file system
to tape. That way I'm not dependent on zfs to get the data back
(and can get individual files/directories back if necessary, which
it often is). And you have the ability to slot that copy of the data
instantly into service if the primary copy fails.

For tar, you can substitute a free or commercial backup solution.
It works the same way.
