+# Alas, although VSPC's job data does specify whether a job runs "daily", it
+# does not tell you which days. Veeam allows "daily" jobs to be configured to
+# run on specific days of the week, which is something we use in production to
+# run certain backup jobs only on a Saturday.
+#
+# So we need to filter through VSPC's somewhat inconsistent policy API to find
+# daily settings. If a job is supposed to run on exactly one day a week, we
+# treat it as weekly, otherwise daily.
+#
+# NB: if we ever use more than one day during the week (e.g. two), the logic in
+# this plugin will need to be changed. The logic here, and in process() above,
+# match what we currently do in prod, since a "better" approach will require a
+# lot more code for a system we might phase out for something else.
