If you support Netbackup at your site, I’m sure you’ve had to look into issues with slow clients and failed backups. The nbstatus script I mentioned in a previous post is useful for identifying connection problems, but it doesn’t help you understand how well your clients are performing. To help me understand how much data my clients are pushing, I wrote the nbthroughput shell script:
$ nbthroughput

The script will display the fastest clients, the slowest clients, and how much data your clients are pushing to your media servers. I find it useful, so I thought I would post it here for others to use.
