LIMIT_BANDWIDTH option for NetBackup servers
This option specifies a limit for the network bandwidth that NetBackup clients use on a network. The actual limiting occurs on the client side of the backup connection. This option limits only backups. Restores are unaffected. The default is that the bandwidth is not limited.
Note:
LIMIT_BANDWIDTH applies only to IPv4 networks. Use the THROTTLE_BANDWIDTH option to limit IPv6 networks.
