Limit bandwith with Copilot

Hello,

we are backing-up a remote Oracle database telling Netbackup to limit the bandwidth to not congestion the network.

We would like to use Copilot but in order to do this we should mount through this limited network the netbackup appliance NFS share.

I don't know if NFS writes can be limited but I am wondering if Netbackup could anyway limit itself in any way writing to the share.

 

Thanks

Regards

    There is no option in NFS itself to limit the bandwidth consumption, nor is there a option in Netbackup itself. 

    So you are looking for other ways to do this either by traffic shaping on the network layer or from the OS by using tc (traffic control) program and by the use of different "qdisc" (queueing discipline) as mentioned by Red Hat in this article  https://access.redhat.com/solutions/69133 (require login)
