exabyte to exabyte copy -- How?

[George Planansky]

I need a way to make copies of our exabyte dump tapes, a couple of
times a week.  These have ten or so dump files on them.

Copytape works for making a copy of 9-track tapes:

   9-track tape drive a  ---> { copytape } ---> 9-track tape drive b

1. Is there a program that will do:

   exabyte tape drive a  ---> { copytape } ---> exabyte tape drive b

(A while back, I couldn't get copytape to work with an exabyte drive.)

2. Is there in fact a way to run exabyte drives to make copies directly:

   exabyte tape drive a  ---> exabyte tape drive b

3. If there is a reasonable way to make duplicates of these exabyte
tapes, I would appreciate hearing of it.

Thanks.
