The NUMBER OF BUFFERS PER STRIPE parameter affects buffer space availability. This parameter is set in the NetBackup MS SQL Client interface for each operation. NetBackup uses this parameter to decide how many buffers to allocate for reading or writing each data stream during a backup or restore operation. By allocating a greater number of buffers, you can affect how quickly NetBackup can send data to the NetBackup master server.

The default value for the NUMBER OF BUFFERS PER STRIPE is 2, which allows double buffering. You may get slightly better performance by increasing this value to a higher value.

In the Microsoft SQL Client interface, you can change this value through the NetBackup client properties dialog box. (File > Set NetBackup client properties). Otherwise, you can use the NUMBUFS parameter to set this value when you create a batch file manually.
