ADSM backups failing because of duplicate volume labels, eventhough the
physical drives have different labels.

This is found because of   subst like  "W:\: => C:\WINNT\Profiles\ADMINI~1"
error message:

Backups can be completed by removing substitutions,  by  "subst  w:  /d"
and rerunning backup again....it completes fine.

But as subst is server admin controlled, adsm backups have no control on these
settings.
Is there any way to avoid the failures, due to subst,  when we backup the
physical drive,
and not the substitution-drive.....

I appreciate your inputs.
Thanks, vijay.
