Wouldn't this work?

   dsmc restore x:\ -subdir=yes -fromdate=mm/dd/yyyy -fromtime=hh:mm:ss
-replace=all

where -fromdate and and -fromtime are the date/time that the image was
taken.

Paul,

If you used the flash-copy (hardware) image to do the restore, then did
a TSM restore with the "ifnewer" parm, how would that be different than
if you used a TSM image?

This might be the answer I was looking for.  But I am concerned that we get
optimal restore performance.  *If* TSM has to position tape, etc, prior to
determining whether the file is newer or not, that would cost time.  Do you
know if this is the case?  This is a filesystem with millions of files.

Thanks again.
