gew@dnlunx.UUCP (Weijers G.A.H.) writes that:  BACKUP/VERIFY does *not*
check whether the data on tape is consistent with the data on disk.

which is strange since it acts like it does.  I know its not buffering
the data in memory when it rereads the tape to compare with and it
seems to access disk just as much.   I know BACKUP/COMPARE does since
it gives error message by disk bblock of file for differences.  Come to
think of it so does BACKUP/verify ...  now if DEC would just release
VMS BACKUP for Ultrix (Ala their FOrtran, C and LISP products.)
