How does one copy a SCSI tape ?

[Farooq Butt]

You have an OS tape. You wish to copy it for safekeeping. You use "dd" but
it doesn't seem to work.  What is a good way to duplicate OS release
tapes.  Again, I reiterate, this copying is merely for safekeeping as
tapes tend to get chewed up at our site ....

  thanks,

ps: If Sun considers this to be "illegal" please let me know as I tend to
be woefully ignorant in these matters of legality.....
