NetBackup Troubleshooting Guide Appendix A contains process flow diagrams as well as detailed explanation.

A Symantec Trainer has shared this easy to read summary in pdf format with me.

I would like to share it here for the benefit of the greater community.

Hi Guys

I created the attached file from the NBU Manual back in the day(NBU6.5). Being a bit of a noobie[I still am] I created it to get my head around the NBU processes. 

It's a power point presentation that shows the process flow, where to look at/for logs and how to stop and start the process. Hopefully it will be of some help to somebody else out there.

Not encrypted, just password-protected.

You should be able to open 'read-only'.

View the doc as a slide show.

You will notice that Figure 1 contains a 'nbgenjob' process which was used to manage multiple streams in NBU 6.0. This process was removed in NBU 6.5. This why I was so glad when I found this new, updated doc.

Same 6.0 doc also published here: http://www.symantec.com/docs/TECH46468

Marianne,

This is a wonderful flow however I found that you do not discribe the Master Server / Client communications that take place during a multistream backup. We found out reciently that we cannot even start then if you have "Allow multiple streams" selected and the master server cannot talk to the client.

The above comments are not to be construed as an official stance of the company I work for; hell half the time they are not even an official stance for me.

The Index Reference card at the top of the thread is simplistic and covers the majority of the logs you'll need for basic backups to tape. The power point is good also for an overview.

The http://www.symantec.com/docs/TECH46468 posted by Marianne is the best public document available. There are mistakes in this document too. The most obvious is the lack of BPCD even being mentioned and others.

The netbackup 7.5 troubleshooting guide gives us more information about the process flow that is correct and accurate. http://www.symantec.com/docs/DOC5180  What is missing is the call backs some processes make shown in Marianne's link. 

There is not one document that shows a lot of the differences when the same process flow is used with other features. (VMware, Accelerator, BMR, Snapshots, etc). The more you know about the product the easier our jobs become. From a Detailed status and the point of failure we know what host to go to and which logs to enable.

To get the most definitive answer on the process flow. Shut down netbackup. Enable verbose = 5 and Vxlogs to 6. Use the mklogdir. Then configure a one file backup all on the master server as the client. Use the Detailed status to give the pid number you'll need to find in the logs along with the above guides as to which log to read first.

The other option is to inquire with Education Services and have a class taught on the subject.

Happy Backup.
