Restore email notification

About the scripts...

Have you tried to read up in NetBackup Administrator's Guide, Volume II   about the notify scripts ?

restore_notify script
The restore_notify.cmd script (on Windows) and the restore_notify script (on
UNIX) run on the server that contains the storage unit. The NetBackup tape or disk
manager (bptm or bpdm) calls the script when it finishes sending data to the client
during a restore. The script is called regardless of whether data is sent.

userreq_notify script
The userreq_notify.cmd script (on Windows) and the userreq_notify script (on
UNIX) run on the master server.
The scripts are located in the following directories:
On Windows: Install_path\VERITAS\NetBackup\bin\userreq_notify.cmd
On UNIX: /usr/openv/netbackup/bin/userreq_notify
NetBackup calls the script each time a request is made to either of the following:
■ List files that are in backups or archives
■ Start a backup, archive, or restore
You can change this script to gather information about user requests to NetBackup.

Sound like userreq_notify is the one you need...
