I believe you have something else happening.  If that option was changing the 
ACLs of millions of files you would be very aware of that happening.  
"administrative" rights are not unlike sudo in Unix, you are assuming the 
identity of a more powerful user.
It is not uncommon for admins here to do what you describe without the results 
you describe.

Subject: [ADSM-L] Win2008 with UAC and backing up files that really didn't 
change... kind'a

OK, so I have a file server with 6 volumes each of 2.5 TB's and each with 
1-2.5M files on them.

Under Win2008 there is this ~funk~ called UAC such that an "administrative"
id has effective permissions to everything but not really any direct permission.

That is, if I go into this server and under explorer I click on the top 
directory on one of the volumes it says "you don't have rights to view this, do 
you want to grant yourself rights?" and when I click "OK" windows goes out and 
gives my userid direct permissions to all subfolders and files. BUT.
that is a change to the permissions of every directory and file and next incr 
backup, TSM backs up everything. yes, sometimes 2.5M files at 2.5 TB's just 
because some admin clicked "OK" on giving themselves permission to view things 
at the top folder level.



Is anyone else seeing this?
