Are backupexec and tsm used for the same client at the same time. If so I believe that one problem, or at least is the reset of the archive bit by backupexec. I seem to remember that this would trigger a backup by tsm.
In general I believe that tsm will backup a file if the file metadata/catalog data changes. I wonder if this is also the case with the use of the subfile feature. Please correct me if I am wrong this is old fuzzy memory as I have not check in the recent past. len -----Original Message----- From: ADSM: Dist Stor Manager [mailto:ads...@vm.marist.edu] On Behalf Of Bill Boyer Sent: Thursday, March 18, 2010 2:34 PM To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] TSM client checklist for backup. Is there a list of what the TSM client checks for on a file to determine if the file needs to be backed up? I have a client that is running both BackupExec and TSM on servers and he's telling me that TSM backs up way more than backupExec and 'what the users have changes.' Using their words. This customer also has TPC Data and is using the Files as Risk report to estimate how much data needs to be backed up. But I think that just goes on the archive bit and the last modification date/time of the files. Which is only a fraction of what TSM uses to determine a file's eligibility for backup.
