netcatを介して失敗した（ZoL）ZFS転送を回復できますか？

埋め込まれた暗号化が利用可能かどうかはわかりませんが（そうだと思います）、通常send -t | recv -sプールでサポートされている場合は、特別なフラグを使用して失敗した転送を回復できます（illumosのドキュメント、zorに関連していると思います）。

zfs send [-Penv] -t receive_resume_token
       Creates a send stream which resumes an interrupted receive.  The
       receive_resume_token is the value of this property on the filesystem or
       volume that was being received into.  See the documentation for zfs
       receive -s for more details.

zfs receive [-Fnsuv] [-o origin=snapshot] filesystem|volume|snapshot
zfs receive [-Fnsuv] [-d|-e] [-o origin=snapshot] filesystem

   -s  If the receive is interrupted, save the partially received state,
       rather than deleting it.  Interruption may be due to premature
       termination of the stream (e.g. due to network failure or failure
       of the remote system if the stream is being read over a network
       connection), a checksum error in the stream, termination of the zfs
       receive process, or unclean shutdown of the system.

       The receive can be resumed with a stream generated by zfs send -t
       token, where the token is the value of the receive_resume_token
       property of the filesystem or volume which is received into.

       To use this flag, the storage pool must have the extensible_dataset
       feature enabled.  See zpool-features(5) for details on ZFS feature
       flags.

zfs receive -A filesystem|volume
       Abort an interrupted zfs receive -s, deleting its saved partially
       received state.
