kb/sec speed is very slow on a Unix client during backup

Hi,

 

I have a unix client with the OS AIX Power system 770. When trying to run a backup, the kb/sec is slow and is fluctuating between 40 and 70 kb/sec. The client is running on a Solaris Netbackup Master and media server. Could this be a network issue on the client machine or data buffer tuning would required to be done on the media server. All the other backups on the clients running through this media server seem fine. If it is a network issue what setting would need to be checked or and also if a media server tuning would required to be done for a lot of clients getting affected with slow kb/sec rate what would be the solution for this ?

Please advise and help with your inputs.

    40-70KB/sec for client - Sound like the client has a speed/duplex issue with it Network card

    General performance tuning is documented in Backup planing and performance tuning guide chapter 2:

    1)fist you need to find that your source data is having the good I/O capablity.. can be check though bpbkar null test

    2) then speed between the media server and client ( use regular FTP or ipefr test)

    3) then load on the media server.

    see the suggestion from Marianne on another post to isolate the slow backups

    Yes, it was an issue with the network card setting which was set right and the backups seemed to function fine post this.

    Thank you for the suggestions and inputs.
