session_start_notify script
The session_start_notify.cmd script (on Windows) and the session_start_notify script (on UNIX) run on the master server. When a set of backups is due to run, NetBackup calls this script to do any site-specific processing before it starts the first backup. NetBackup passes no parameters to this script.
To use this script, copy the script to the bin directory:
UNIX:
/usr/openv/netbackup/bin/goodies/session_start_notify to /usr/openv/netbackup/bin
Windows:
install_path\netbackup\bin\goodies\session_start_notify.cmd to install_path\netbackup\bin
Modify the script and confirm that you have permission to run the script.
