Maybe 'shadow migration' ?  (eg: zfs create -o shadow=nfs://server/dir

Hm, interesting, so it works as a sort of replication system, except
that the data needs to be read-only and you can start accessing it on
the target before the initial sync. Did I get that right?

The source filesystem needs to be read-only. It works at the VFS layer so it doesn't copy snapshots or clones over. Once mounted it appears like all the original data is instantly there.

There is an (optional) shadowd that pushes the migration along, but it will complete on its own anyway.

shadowstat(1M) gives information on the status of the migrations.
