Hello -

        I am going to a client site next week that is having a problem with
incrementals.  Scenario follows setup.

        Unisys NT 4.0 SP6, 4x700MHz, 2GB Memory, 2x18GB disk  (MASTER/MEDIA-
EVERYTHING direct connected)
        (2) Adaptec 3944 Dual Channel Scsi Card
        (1) Adaptec 2944 Robot Control
        STK L700 v2.00.00
        (4) 9840 drives v1.25.116
        (1)   7TB EMC ARRAY   -  3 1/2 TB in use.

        Client breaks mirror on EMC array and REBOOTS NT Master/Media server
to create BCV Local Drive Meta VOlume 500GB G:\.
        
        Client then kicks manual incremental backup of data.  This happens
each day until each metavolume is backed up.

        The data is NOT accessed in ANY OTHER WAY.   It is not a database.
It is literally 10 million image files of tax return forms that are not in a
database, not on a website, not anything.  They are static and only accessed
for backup.   New files get added, though.  1TB /year.

        When the backup occurs, some kind of change must happen to one of
the times on the files - a bit must change - because an incremental is
ALWAYS a FULL backup.   Daily, each metavolume may have 1MB to 10GB added -
but no changes to existing files or file directories.  Just new files and
directories.  

        Any ideas as to how to fix the time problem so that incrementals are
only the new files/directories?

        Thanks.
