Ok, only a note to say, afer some long time, that i've abandoned the 'zfs
snapshot' script.

After some test in some real wold scenario i got without snapshot:

        14-Nov 17:43 svpve3-sd JobId 29940: Elapsed time=48:14:20, Transfer rate=19.31 M Bytes/second
          FD Files Written:       22,001,262
          FD Bytes Written:       3,348,102,512,393 (3.348 TB)

and with snapshot:

        21-Nov 16:03 svpve3-sd JobId 30339: Elapsed time=47:19:10, Transfer rate=19.69 M Bytes/second
          FD Files Written:       21,997,689
          FD Bytes Written:       3,348,098,003,450 (3.348 TB)

a roughly 1,9% gain. Probably other scenario can gain better (or worster)
but this is mine, an considering the complication of handing path with
'strippath' in the game.

Simply, it's not worth.
