[ADSM-L] AW: How can I exclude files from dedupe processing?

Hallo John, Paul,

 

for client dedup, have a look to exclude.dedup  option

 

And: compressed objects can also be good candidates for deduplication. Have
a try and test reduction(s)

Deduplication is an attribute of a a storage pool.  If you have data you
don't wish to de duplicate, you would need a separate storage pool.

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.

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?
