Thanks for the lesson in copying tapes! I am looking into the "native"
COPY command in BackPack. You may or may not be aware that BackPack puts a
limited copy of itself, BPREST, at the beginning of the tape and in MPE/iX
STORE format so that the recipient need not already have the BackPack
product. I am waiting for a response from ROC as to whether the COPY does
that as well.
Mike: do you know the answer to this question?
