I think is B. # cd /; tar cvf /tmp/sue.tar sue By default the tar utility uses (scsi) tape as medium. As can be seen in the example above scsi tape devices can be found in /dev/st* or /dev/nst*. The latter one is a NON rewinding tape, this means that the tape does not rewind automatically after each operation. This is an important feature for backups, because otherwise when using multiple tar commands for backups any backup but the last would be overwritten by the next backup.

mmm... Ok, my mistake I I also read: "The major difference is after perform a task, /dev/st0 will rewind to begining of tape, but the /dev/nst0 won't." The answer is: D
