Our default is to keep archives for two months.  For class related lists, we keep them for four months which covers a semester.  We like to have logs to help diagnose problems. We've started adding a Notebook-Header= Full to provide additional information to track problems.

We run a job every Saturday evening that purges old archive files.  We keep a separate file, read by the Saturday job, that has a list of retention periods.  Some lists we just keep a week.  Others are kept forever.  A few have explicitly asked for no archives at all.
