I'm actually familiar with SAS, which is a Stand Alone Sequencer from Apparent Networks. It's designed to send a specific sequence of packets that traverse the network and then based on the order in which they come back Apparent Networks then produces a report about potential network problems.
We got another tool called iperf, which is another standalone binary that is allowing us to perform some network utilization testing.

The tool utilizes ICMP so its much easier to use than anything port based and its given me some very good feedback when trying to utilize 100% of our gigabit pipes. Between the bpbkar utility and SAS utility I've been able to identify many bottlenecks and it assists greatly when performance tuning your network options. For my money its much better to isolate the local disk with bpbkar32 > null then the network pipe w/ SAS than to use bpbkar32 in an actual backup setting and try to read log files. -Jonathan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ellis, Jason Sent: Monday, October 16, 2006 7:03 PM To: [email protected] Subject: [Veritas-bu] Running bpbkar32 from the command line Got a good one for the group... We're trying to do some bottleneck testing and are running into a problem with the FTP ports being closed down on our Windows systems, thus we cannot really test the network between the clients and media servers. We're trying to see if we can kick off bpbkar32 manually to just move a single file to disk on the media server to test the network like and FTP would. I know we test the client side locally by running: bpbkar32 -nocont [file_path_to_test] 1> nul 2> nul I also know that bpbrm is the process responsible for starting bpbkar32 and passes all the information bpbkar32 needs to start the backup. One thought is to enable the bpbrm log file and see what options are being passed, however if anybody out there has already done this and can give me a breakdown of running bpbkar32 manually that would be great! Thanks in advanced!
