Bandwidth properties
Use the Bandwidth properties to specify network bandwidth limits for the NetBackup clients of the selected server.
Note:
The actual limiting occurs on the client side of the backup connection. The bandwidth limits only restrict bandwidth during backups. By default, the bandwidth is not limited.
The Bandwidth properties apply to currently selected master servers.
To manage entries in the Bandwidth dialog box, select one of the following buttons.
Adds an entry to the bandwidth table for each of the selected clients. | |
Changes an entry to the bandwidth table for each of the selected clients. | |
Removes the selected entry from the bandwidth table. |
When a backup starts, NetBackup reads the bandwidth limit configuration as configured in the Bandwidth host properties. NetBackup then determines the appropriate bandwidth value and passes it to the client. NetBackup computes the bandwidth for each new job based on the number of jobs that are currently running for the IP range. NetBackup does not include local backups in its calculations.
The NetBackup client software enforces the bandwidth limit. Before a buffer is written to the network, client software calculates the current value for kilobytes per second and adjusts its transfer rate if necessary.
