How to reduce the file backup rate on NetBackup?
The following example show how the reduce file backup rate. In the example, the NetBackup policy name is 8807, client name is linux8807_eth2, NetBackup master server name is linux128.

1. Check the backup policy of 8807, confirm the policy type is "Standard",  Linux file backup policy type is "standard", and this case only use for "standard" policy type.
2. If "Allow multiple data streams" in backup policy is selected, please cancel  "Allow multiple data streams" box.

3. Open the NBU master server properties, set "Bandwidth" property to limit the backup bandwidth. For example, limit bandwidth of client linux8807_eth2(backup IP is to 10000KB/sec, “from host” and “to host” are IP of same client. The /etc/hosts on NBU master server can get the IP mapping of backup client.
NOTE: All backup policies on this client will be limited if bandwidth is configured.

 4. Bandwidth property will take effect after restarting nbu services.

1> stop NBU services
# /usr/openv/netbackup/bin/bp.kill_all
2> check NBU services use 'bpps' command and confirm all progresses have stoped, if some progresses can not stop, manually kill it(for example, kill -9 xxx).
# /usr/openv/netbackup/bin/bpps
3> start NBU services.
# /usr/openv/netbackup/bin/bp.start_all
