Andy,

 

See this LINKS:

https://www-secure.symantec.com/connect/forums/netbackup-7-compression

http://www.symantec.com/deduplication

 

Symantec Deduplication Calculator:

http://eval.symantec.com/flashdemos/products/netbackup/dedupe_calc2/

 

This links have all information do you need know about the Netbackup Compression and Deduplication.

 

Just more one information, the Netbackup Compression dont need a separeted license, but Deduplication have a separete license to use, I recommend you use both, because some policys and file types dont need to be dedup because you dont have much gain, but the others file types have a high compression rate when use deduplication.

thank you for your infomation .

form your infomation ,NBU software compression(policy-base compession which is used before deduplication  ) uses Lempel-Ziv (LZ) compression,but which  algorithm the deduplicatiopn compression (in pd.conf,there is a compression option which is used after deduplication ) use is not mentioned .
