    Hi,

     

    • 32 TB is what you can assign to the Media Server, what the protected value is depends on dedupe rates in your environment.
    • This would depend on your environment but take a look at the guide for some more information http://www.symantec.com/docs/DOC3657
    • I think Netbackup uses fixed block, didn't find any documentation on this.
    • NetBackup reserves 10% of the 32TB for the Database. It might not reach that figure but its a protection measure.

Based on the training material I have, you can select either fixed or variable block size within your Advanced Disk Pool. You are not limited to either.  Have a look at the following: http://www.symantec.com/business/support/resources/sites/BUSINESS/content/live/DOCUMENTATION/3000/DOC3657/en_US/NetBackup_Dedupe_Guide.pdf

In terms of hardware dedup, Symantec Netbackup uses the term:  OpenStorage dedup.  As long as you have the correct license, you can dedup at either the client, media server or Disk appliance level.

Hope that helps.  AlfredMJNZ
