I think there's room for many possible designs here depending on the use
cases. Luckily the plugin system will give us the flexibility to
experiment with these designs. I wouldn't say we're ignoring you, just
exploring our options.

I consider myself a pretty technical person, but I'm still pretty new to
ZFS and have yet to try out RAID-Z and pool replication. If we hope to
have the widest impact, we'll need a variety of backup solutions.

I'm most interested in the case where you can just install a plugin and
have a mostly reliable, realtime, encrypted, streaming backup. This is
something people can enable no matter what hardware or filesystem
they're running on.

I agree, we should should be building instead of arguing. I don't think
the arguing has been unproductive, I'm going to be looking more into ZFS
replication with my setup.

Cheers,
Will
