ZFS-enhanced way to copy files over network?

What is the best way to copy files from one computer to another using ZFS or checksumming?

I have a FreeNAS server with ZFS and a Mac with Mojave and ZFS.

I want to copy a large (4 TB) Time Machine sparsebundle from the server to the ZVOL on the Mac over the network.

I wonder if there is a ZFS-enhanced way to do this, which perhaps includes metadata or checksums.

Apparently ZFS only includes options for copying (send/receive) complete filesystems or volumes, not individual files.

I found the command

cp -z

on an Oracle online manual, but this apparently does not work in the macOS terminal.

Any idea?

zfs cp macos freebsd

There is no way to leverage ZFS for this using any of it's features other than send/receive. Unless you are transferring an whole fs or volume snapshot (full or incremental), ZFS can't help you.
