NetBackup Encryption Option Info for Solution Engineers

This document provides solution engineers with implementation details and performance impact of the NetBackup Encryption option. It discusses how software-based encryption affects backup performance on different levels and recommends encrypting only customer-related data. The document also includes preliminary performance results based on internal VERITAS test data, noting the small difference in performance between 128-bit and 256-bit AES encryption.

  1. NetBackup Encryption Option Info for Solution Engineers For Internal Use Only

  2. NetBackup Encryption Option implementation details • Software based encryption affects backup performance on 2 levels • Increases time to complete backup based on the bit-level of encryption • CPU utilization increases at the client for both backup and recovery • Recommend encrypting only customer related data An approximation of performance impact** ** Internal VERITAS test data. Results will vary for customers based on data and hardware

  3. Preliminary Encryption Option Performance - Baseline Note the relatively small performance difference between 128 & 256-AES.
