I have doubt on BPSTART_TIMEOUT working.

[MG11]

So suppose i have set bpstart_timeout value to 800 seconds in my bp.conf on master server

My backup has 8 seperate streams.
So this bpstart time out is for all individual streams 

will it wait for 800 seconds for stream 1 to complete before it gets timedout
Or this 800 seconds is for complete backup ?

And when we say bpstart started and bpstarted finished ..by bpstart finished what we actually mean what netbackup looks for before saying bpstart complete ? Does it mean that stream 1 is about to start actual data transfer ?

Are you using bpstart_notify on one or more clients?

bpstart_timeout only applies to client backups where bpstart_notify scripts have been implemented on clients. 
bpstart_notify script on client needs to complete before bpstart_timeout value.

Please read up in NBU Admin Guide II how bpstart_timeout is linked to bpstart_notify:

Backup start notify timeout is also explained in Admin Guide I under :
