Hi Hans,

I've been snagged by this on many occasions myself.  The worst time was when 40 
TB of data had to get backed up again because a system admin made a simple 
permission change at the root directory.

I agree with you that since TSM now uses DB2 for its database, it should be 
able to handle storing permissions for Windows clients in the TSM database, 
just like it does for Linux clients.  If you're willing to create an RFE, I'll 
vote for it!

When our customers changes permissions on their file servers there is total 
chaos with new full backup of everything and no practical method to get rid of 
the extra backup data. I think our customers should be able to do this without 
paying twice as much for their backups.

From what I have heard TSM couldn't just update these files because there is 
too much overhead keeping this information in the database. However in the 
meantime TSM has gone from the proprietary database in v5 to a full DB2 which 
should handle this well.

It would be nice if IBM took a look at this problem and came up with a 
solution. Don't know if other TSM admins think this is an issue though.
