About the NetBackup data transfer path
The overall performance of NetBackup is limited by the slowest component in the backup system. For example, a fast tape drive that is combined with an overloaded server yields poor performance. A fast tape drive on a slow network also yields poor performance.
The backup system is referred to as the data transfer path. The path usually starts at the data on the disk and ends with a backup copy on tape or disk.
This chapter subdivides the standard NetBackup data transfer path into four components: the NetBackup client, the network, the NetBackup server, and the storage device.
This chapter discusses NetBackup performance evaluation and improvement from a testing perspective. It describes ways to isolate performance variables to learn the effect of each variable on overall system performance. It also describes how to optimize NetBackup performance with regard to those variables. It may not be possible to optimize every variable on your production system.
Note:
The requirements for database backups may not be the same as for file system backups. This information in this chapter applies to file system backups unless otherwise noted.
