Pete, Due to the virus scan on a non-journaled backup client, would the metadata be updated at the TSM server ? And when a file is listed as updated in the TSM client log how much data is actually being sent ? Last but not least, is this functionality different in other versions of the TSM server and client ? I am running a 4.1 server on AIX 4.3.3 and varying versions of the NT clients from 4.1.2.12 - 4.1.3.0 . I plan on migrating soon to 4.2 server and all 4.2 clients.

In almost all cases, the worst case scenario is that Journal Based Backup will revert to a traditional progressive incremental backup and no additional objects will be backed up. The one possible exception is when virus protection (or potentially other) software saves objects object attributes (for example, last access date/time stamp), modifies them, and then resets them to their original value. In this scenario objects processed by the virus protection software will not be backed up again by traditional incremental backup because candidates for backup are selected based on attribute comparison between the local copy of the object and the copy of the object on the TSM server. Since the Journal service monitors real-time change activity to the filesystem, each object processed by the anti-virus software will generate a change notification and will cause an entry to be added to the journal database, and since Journal Based Backup selects backup candidates based solely on the contents of the journal every object process by the virus protection software (usually the entire filesystem) will be backed up again. Symantec has a fix available for Norton Anti-Virus which allows the caching/resetting of attributes to be turned off during Nav scan processing (please see the TSM readme file for details about obtaining the fix). Anyway, you might want to try turning off any virus protection software (Symantec or otherwise). Hope this helps .....

I've never heard of a journal-based backup causing a backup of the entire machine.... do we even know whether James is running the journal service? It might help to know how often these full backups occur, and if there is any pattern. Also, is it possible that someone is altering any copygroup settings, perhaps changing the MODE from MODIFIED to ABSOLUTE? Maybe the file space is getting renamed or deleted?

Yes but it keeps the list locally and sometimes I think it gets confused so it just backs everything up again... -----Original Message----- From: Ochs, Duane [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 21, 2002 5:33 PM To: [EMAIL PROTECTED] Subject: Re: Why are all my NT files getting backed up again? I thought journaling creates a list of changed files and prevents the system from scanning every file that didn't change in order to find the ones that did change.

James, are you running the Journaling service? I think I remember a similar problem that was fixed by removing it. -----Original Message----- From: Louie, James [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 21, 2002 4:39 PM To: [EMAIL PROTECTED] Subject: Why are all my NT files getting backed up again? I have a few NT4 servers with TSM 4.2.1.20 client that occasionally do a full backup instead of an incremental. There are many files that have no change in size or date or permissions (at least that I can see). I just turned file auditing on to see if I can catch anything. Any ideas on what may trigger a full backup? Thanks in advance. James Louie Philip Morris Management Corp.
