EDIT: you CAN write the zfs stream directly to tape (using plain
output redirection, without using tar) so you don't need a temporary
file (at least this is true in Linux), but it's kinda awkward since
you need to remember (or store somewhere else) where the zfs stream
was from and what file number (on the tape) stores the stream.

So again I suggest you use disk as backup media when possible.
