We mostly rely on AMANDA, but for a simple, compressed, encrypted,
tape-spanning alternative backup (intended for disaster recovery) we use:
tar cf - files | lzf (quick compression utility) | ssl (to encrypt) | mbuffer
(which writes to tape and looks after tape changes)
Recovery is exactly the

Having this feature seems like a no-brainer to me. Who cares if SVM/
UFS/whatever didn't have it. ZFS is different from those. This is
another area where ZFS could thumb its nose at those relative
dinosaurs, feature-wise, and I argue that this is an important
feature to have.

I'm not sure the best way to do this, but my thought was to have ZFS
