Certainly I feel it is difficult, but is it logically impossible to write a

I'm wondering if somebody can kindly direct me to a sort of newbie way of

Hi Toyama,
You cannot restore an individual file from a snapshot stream like
the ufsrestore command. If you have snapshots stored on your
system, you might be able to access them from the .zfs/snapshot

Hi--
Pool names must contain alphanumeric characters as described here:

The problem you might be having is probably with an special characters,

And a very nice device it is indeed.
However for my purposes it doesn't work as it doesn't fit into a 2.5" slot and
use sata/sas connections.
Unfortunately all my pci express slots are in use.
