Question about capacity license model

Hello, we were told that we have to switch our current traditional netbackup licenses to capactiy ones since otherwise we will not be able to extend our current support agreement.   I was running ...

    there is no problem with the restore. It does not count any data against licenses

HI mst1  The new capacity license model uses the FETB or Front-End Terabyte to calculate the actual data  protected for a client (Front end).  It does not measure the capacity of the storage where the data resides or the total amount of data that is stored on the device. That means, it will only consider the data that is protected irrespective of the number of copies or times it is backed.


For the FETB calculation,it takes a backup of the last 90 days with the assumption that we would have a Full backup of the client at least once in a quarter. Or to put it simple , it will pick the largest FULL backup in the last 90 days.
To get to the FETB value, it adds the Largest Full backup of each Policy / Client combination from the last 90 days.

Consider the following:

  1. Assume a device with 100 TB of total storage capacity.
  2. A total of 65 TB of the total capacity is in use.
  3. NetBackup protects a total of 60 TB of the used data through multiple backup storage units.
  4. That is measured as 60 TB of front-end capacity.

The total terabytes of front-end capacity are independent of the number of copies NetBackup makes. A backup of 200 TB to basic disk with two copies to tape is still only 200TB of front-end capacity.

    Hello DeepS,

    thank you very much.

    So if i did a huge full backup of a client 100 days before, and only differential from there on, would this mean for the FETB cacluation this huge full backup does not count?

    Lets say a huge full backup of 50 TB was made 100 days ago (for archiving reasons). In the last 90 days only differential backups were made for this client with much less data in total (say 5 TB), would a 5 FETB capacity license be sufficient?
