This is a script to monitor Netbackup policy changes. It is extremely basic as I am not a programmer but it does meet my needs. It runs the bppllist command to an output that sets the benchmark and then when run on a daily basis it simply does a diff from the benchmark output.
Also, it creates a tarfile of the class (policies) directory and saves it for 30 days. This has helped eliminate the need for doing a restore when a policy is accidently deleted.
