[gpfsug-discuss] mmbackup with own policy

[T.A. Yeep]

Hi Dr. Martin,

You can refer to the Administrator Guide > Chapter 30 > Policies for
automating file management, or access via the link below. If you downloaded
a PDF, it starts with page 487.
https://www.ibm.com/docs/en/spectrum-scale/5.1.0?topic=management-policy-rules

There a quite a number of examples in that chapter too which can help you
establish a good understanding of how to write one yourself.
