"Measuring Front-end Terabyte" in NetBackup

Hi,

I have NetBackup environment and would like to perform license conversion from traditional into capacity based licensing.

I understand that only source, protected data by NetBackup or "current largest full or syntetic backup" should be calculated as "Front End TBs" as per "NetBackup Licensing and Protection Services" guide.

Also, capacity growth for next years should be predicted into capacity calculations.

My questions is, how to measure "Front End TBs" capacity for NetBackup clients where "data archiving" is performed for unlimited time period?

    1. It is again "current largest" full backup or

    2. "aggregated full" from all data archives maintained by NetBackup catalog?

 

Thanks,

  • The 1st one is correct:

    1. It is again "current largest" full backup .

  • Hmmm, but its not a backup, its an archive. If I understand correctly he's referring to a user archive which means it will constantly be different data that is "protected"?

     

    I don't think the policy kept this in mind :P

  • Hi,

    Can you give me consistent answer?

    Acording to the "NetBackup Licensing and Protection Services" guide:

    Measuring Front-end Terabyte
    NetBackup Platform model uses front-end terabyte as the licensing meter. Front-end terabyte is defined as the total
    aggregate amount of data on Clients or Devices on which NetBackup is installed or for which NetBackup is used to
    provide backup functionality. Data is measured as the current largest aggregate full (or synthetic full) backup performed.
    A terabyte is defined as 1024 gigabytes. Please note:
     Data that is no longer on the client but the backup image is maintained by NetBackup. This data is not included in
    the calculated number of front-end terabytes
     Primary storage performs deduplication. The quantity of pre-deduplicated data is calculated
     Archived data is not calculated unless it is backed up by NetBackup. If achieved data is protected by NetBackup
    then the amount of data residing in the archive is measured

     

    If data from NetBackup clients is archived (with user archive) to unlimited time period "which is similar" to last bulet from the text above, it seams that whole capacity that is maintained under NetBackup catalog should be licensed?

    Is this correct?

     

    Thanks,

  • I believe the point referring to archived data is not referring to data that was archived via a netbackup user_archive shedule.

     

    I think it refers to systems archived using for instance Enterprise Vault. This will only be included in front end capacity if you actually backup the Enteprise Vault Stores.

     

    I think you should ask a Symantec SE about this and report back.

  • Hi

    The nbdeployutil is available (in netbackup\bin\admincmd\ or downloadable if not on V7) which helps calculate the estimated capacity.

    This has no mention of any archived data on its explanation fields of the ones that i have run but perhaps if it detects archived data it may give different results

    It may be worth a try to see what it gives you:

    see this pdf for more details:

  • At the end if the day if you were to do a full backup of everything you wanted to protect using NBU, what would that amount equate to?  That is typically the answer.  Factor in growth for the remaining year, and you're set.

    You will true up each year as needed when you do your renewals.
