parent_notify_script issue (NetBackup 22.214.171.124, Solaris 10 master server)
We have two Exchange 2007 Server clusters in two different locations (two separate policies). Our disk storage is tight in both locations so I created a script for each location that deletes an unexpired backup image when I need to free up more space for a new backup. I call my image_deletion script in the NetBackup parent_start_notify script for these jobs so I can avoid Status 129 (disk space full) errors. In one location this setup is working flawlessly, backups always successful, images deleted as needed.
In the other location sometimes the backup fails due to disk space being used by other backup polices that use the same disk space. When that happens we get a Staus 129 error and the job retries again and again. But even though the retry attempts show up as new jobs in the Activity Monitor, the parent_notify_script does not seem to run again, so my image_deletion script does not get called to free up the required free space.
Isn't it normal for the parent_notify_script to be run each time a backup is begun, even if the job is a retry of a previously unsuccessful backup job?
Or am I misunderstanding how NetBackup works?
