If your running Solaris, you could try the  'tcopy' command.
 From the man pages -

NAME
      tcopy - copy a magnetic tape

SYNOPSIS
      tcopy source [destination]

DESCRIPTION
      The tcopy utility copies the magnetic tape  mounted  on  the
      tape  drive  specified  by  the  source  argument.  The only
      assumption made about the contents of a tape is  that  there
      are two tape marks at the end.

      When only a source drive is specified, tcopy scans the tape,
      and displays information about the sizes of records and tape
      files.  If a destination is specified, tcopy makes a  copies
      the  source  tape  onto  the destination tape, with blocking
      preserved. As it copies, tcopy produces the same  output  as
      it does when only scanning a tape.

      The tcopy utility requires the  use  of  Berkeley-compatible
      device names. For example,

      example% tcopy /dev/rmt/1b /dev/rmt/2b

REMEMBER - the safety of your data is your responsibility
If it's important to you - ** MAKE A COPY ** or 2 or 3 or 4 or ........

There is only one certainty about storage systems - they *will* fail !
