I'm not completely sure I understand this.
Are you making a backup to vtapes (on disk).
And than make a backup of those vtapes to ptapes?

So a restore from physical tape than means:
First restore a backup image for each backup level from ptape
to vtape.
Then restore the needed files from vtape images.


If all you want is having a backup on vtapes (for fast/easy
restore) and on ptapes (for e.g. offsite storage), then have a look
at the rait:  you can use it to mirror a backup to two different
set of tapes (one being a set of vtapes):

The naive two-stage approach that I understand you are implementing
has a lot of drawbacks (e.g. there is no "index" for a restored vtape
image, use of amrestore is not possible in that case; besides the
duplication of the volume of bytes that is transferred of course.)
