Pool names must contain alphanumeric characters as described here:

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
directory. See below.
Thanks,
