Measuring NetBackup performance: overview
The final measure of NetBackup performance is the following:
The length of time that is required for backup operations to complete (usually known as the backup window).
The length of time that is required for a critical restore operation to complete.
However, to measure and improve performance calls for performance metrics more reliable and reproducible than wall clock time. This chapter discusses these metrics in more detail.
After establishing accurate metrics as described here, you can measure the current performance of NetBackup and your system components to compile a baseline performance benchmark. With a baseline, you can apply changes in a controlled way. By measuring performance after each change, you can accurately measure the effect of each change on NetBackup performance.
