Note sure if this is any help, but.......

Normally we DO NOT write  twins when running VMArchive.
(The main reason for this is that with only two tape drives you
couldn't then do merge/purge correctly)

However to make sure that we  are in a 'reasonable' position to get
back a file  in the event of  a tape crash, we use  VMBTCPY EXEC to
copy each  set of VMARCH  tapes as it is  closed and move  the copy
offsite.

As in  your case its  fairly simple to  use the output  from VMARCH
VOLUME QUERY to determine which tapes need to be copied.

Note: I seem to recall something having been said at one time about
      the need  to be careful  when copying VMBACKUP tapes  as they
      sometimes have very long reocrd/block length, hence VMBTCPY.
