How capacity licensing uses Front-end Terabytes
The licensing fees for the use of NetBackup are based on the total number of Front-End Terabytes (FETBs) protected by NetBackup. Front-End Terabyte Calculation is a way of determining the total terabytes of data NetBackup protects. One FETB is 1 TB of protected data. The data can either be on clients or devices where the software is installed or where the software is used to provide backup functionality.
The nbdeployutil utility uses accurate licensing or image headers in the NetBackup catalog to determine the terabytes of data that NetBackup protects. Any partial terabyte of data is rounded up to the next whole terabyte. The final total is the sum of the FETBs for each client or policy combination that the analyzer examines. The utility measures the actual data protected.
