This must have been an issue of the USB key; I've plug'ed in another
one:

Aug  5 13:53:12 rebelion kernel: da0 at umass-sim0 bus 0 target 0 lun 0
Aug  5 13:53:12 rebelion kernel: da0: <Generic USB Flash Drive 1.00> Removable Direct Access SCSI-2 device 
Aug  5 13:53:12 rebelion kernel: da0: 40.000MB/s transfers
Aug  5 13:53:12 rebelion kernel: da0: 2037MB (4171776 512 byte sectors: 255H 63S/T 259C)

and the restore of about 600 MByte was done in half hour;

sorry for bother the list with this;
