How to make restore sessions not disappear

A client asked me today to help out with an auditing problem. They need to show to their auditors that they have demonstrated the ability to recover from a backup regularly.

But by default, Data Protector removes any restore session older than 30 days.

The magic variable is KeepObsoleteSessions and it is in /etc/opt/omni/server/options/globals (or on Windows C:\ProgramData\omniback\config\server\options\global or some variation depending on where you installed it).

I set KeepObsoleteSessions=3650, which means that they will still see their restore sessions 10 years from today.

Of course, they will also see barcode scanning sessions, backup sessions without media and various other irrelevant sessions, but they are happy with that.
