Andy,   See this



See this LINKS:


Symantec Deduplication Calculator:


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

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 .
