Using bpstart_notify to mount LUNs doesn't backs up data

[GoodspeedRS]

I'm using bpstart_notify to run a script that will run a storage snapshot function and mount some LUNs to directories (/backup/disk1, /backup/disk2...) with several GBs each.
The server is an HP-UX IA-64 NBU Standard Client 6.5.3.1.

At the beginning of the backup job it takes long enough to run the script (the same amount of  time when I run the script manually) and when the Netbackup start writing to tape, it only backs up the empty directories (disk1, disk2...).

When the backup job start, before the script run, Netbackup estimates the backup size and says has only 32Kb of data (the directories are stil empty).

It seems that NetBackup backs up only the data found during the estimate, before the disks are mounted, even the disks are mounted with data in it.

Any ideas?

Is "cross mount points" enabled in ths policy ?

try
backup/disk1/*
backup/disk2/*

 Can you please post the script ?

Why not use Snapshot Client feature?
I't requires aditional license but works 100%. The whole process is automated - no scripting or manual intervention required.

When you run the script manually is the data available??

We don't use bpstart_notify in this case.
We made a shell scriot that initially makes all the LUN operations and FS mounting and then invokes bpbackup utility. Bare in mind that in this case you are able to effectively control the status code of each operation of snapshot creation and FS mounting.

Maintaining such scripts  is rather painful but  this is a sole mean to backup tons of data.

It wasn't.
After checked "Cross mount point" it worked as it should.

Thanks Nicolai!

I'm very impressed with the Symantec Partner Forum. Thanks for all the answers!
