Backup is extremely slow

Question

I'm using Networker 7.3.2 to backup my client. But the rate is extremely slow, reaching only 25KB/s. How can I determine if this is Networker's issue or other issue. please advise. Thanks

The simplest way is to reproduce same data path (client to storage node via push and get methods) with some OS tool like ftp or ssh and see what values do you get.

Tried ftp from client to storage node. The speed is about 170KB/sDoes that mean the Networker is having issue?

It is quite slow.It must be better, if you use 100mb ethernet.Which is client architecture?Did you transfer big files or smaller one?First check the routing tables on both side.Secondly, check if the client and server can resolve each ip address, and the server backup interface in the client properties.Third:Try to catch some traffic between server ond client.Useful tools for this:Windows: Ethereal (www.ethereal.com)Solaris: snoop (build in the OS)It can be helpful.Regards:Paul

I think it is a networking issue ...

I don't think this is NW issue as you get 170KB/s with ftp which is silly. Issue could be NIC or switch port which is set to wrong mode (in 80% of cases that's it), strange issue with blades when [not] using teaming (I never really understood that one and it happens with Broadcom cards only) or some other network parameter. The only valid issue where this speed would be expected is if you have HDFS, but I was under assumption you don't have one.
