When we see that symptom, it typically means that some Windows admin has changed the ACLs on files and pushed it down to all the subfolders.
Typically they are changing permissions back and forth trying to resolve some issue without realizing that they are causing the TSM server to backup the files repeatedly. Ben -----Original Message----- From: ADSM: Dist Stor Manager [mailto:ADSM-L@VM.MARIST.EDU] On Behalf Of Thomas Denier Sent: Thursday, October 18, 2012 9:51 AM To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] Odd client behavior We recently noticed an unexpectedly rapid increase in database space usage on one of our TSM servers. This seems to be the result of two Windows clients that are consistently backing up hundreds of thousands of files every night. We checked our other two TSM servers and found two more Windows clients behaving this way. In all four cases the behavior started during the same backup window: late October 9 and early October 10. All four systems are in the same Windows domain. The domain administrator does not recall any noteworthy updates on October 9. One of the Windows administrators involved looked at dsmsched.log and reported that the backups include large numbers of files that have not been updated or even accessed recently. The four Windows clients have, among them, three Windows levels (XP, 2003, and 2008), two TSM client levels (5.3 and 6.2), and three groups of people responsible for system administration. The three TSM servers involved include one 5.5 server and two 6.2 servers. All run under zSeries Linux. I would appreciate any suggestions regarding possible causes for this behavior.
