Hallo John, Paul,
for client dedup, have a look to exclude.dedup option And: compressed objects can also be good candidates for deduplication.

If you have data you don't wish to de duplicate, you would need a separate storage pool. ..Paul (sent from my iPhone) On Aug 3, 2015, at 8:19 AM, Dury, John C. < <mailto:jd...@duqlight.com%3cmailto:jd...@duqlight.com> jd...@duqlight.com<mailto:jd...@duqlight.com>> wrote: Unfortunately the final storage pool is the dedupe pool.

Since the files are already using a separate management class, you can just= change the destination storage pool for that class to go to a non-duplicat= ed storage pool. ..Paul (sent from my iPhone) On Aug 2, 2015, at 11:07 AM, Dury, John C. < <mailto:jd...@duqlight.com%3cmailto:jd...@duqlight.com> jd...@duqlight.com<mailto:jd...@duqlight.com>< <mailto:JDury=%2...@duqlight.com%3chttp://DUQLIGHT.COM> mailto:JDury= @DUQLIGHT.COM<http://DUQLIGHT.COM>< <mailto:jd...@duqlight.com%3cmailto:JDury=%2...@duqlight.com%3cmailto:20@DUQLI GHT.COM> mailto:jd...@duqlight.com%3cmailto:JDury=%2...@duqlight.com<mailto:20@DUQLIGHT .COM>>>> wrote: I have a 6.3.5.100 Linux server and several TSM 7.1.0.0 Linux clients. Thos= e linux clients are dumping several Large Oracle databases using compressio= n, and then those files are being backed up to TSM. Because the files are c= ompressed when dumped via RMAN, they are not good candidates for dedupe pro= cessing. Is there any way to have them excluded from dedupe server processi= ng ? I know I can exclude them from client dedupe processing which I am not= doing on this client anyways. I have the SERVERDEDUPTXNLIMIT limit set to = 200, but these rman dumps are smaller than 200g. I have our DBAs investigat= ing using TDP for Oracle, but until then, I would like to exclude these fil= es from dedupe processing as I suspect it is causing issues with space recl= amation. If it helps, these files are in their own management class also. Ideas?
