yes, i have the exact same problem on one drive on one server.  i can do a
full backup, about 19 gig, and then do an incremental backup and it will get
over 14 gig:
 
id     class type       client  date       time        kbytes    #files

i also tried going by the date instead of archive bit, but that didn't help.
i created a logs\bpbkar directory on the client to log what was happening,
and found:

so when it gets the "access is denied", i'm guessing it can't read either
the time or archive bit, so it backs up the file.  it doesn't make sense why
it only happens on one drive on the server, when it works for the others.
also,  it didn't do this initially, it just started happening last year.
i've tried to do some research but haven't found anything yet.  it hasn't
been a high priority, it only wastes some tape, and at least it is backing
up too much, instead of not enough.  
 
good luck,
jerald iverson

Subject: [Veritas-bu] Incrementals are backing up unmodified files


Hopefully someone out there has seen this before and can help me out.

I am using Netbackup BusinesServer 3.4.1. One of the clients being backed-up
is a NT 4.0 SP5. 
The problem I am having is that daily Incrementals are always backing-up
every file in one of the
subdirectories (F:\Users). These are files that have not being modified for
a really long time, even
for a year. The archive bit is not set. I even changed the Netbackup setting
to use modification date 
rather than archive bit and same behavior.  It doesn't happen with other
directories in the same disk, 
only with this one. No problem reported in the logs. 

Regards,
Rafael.
