+    Set the backup schedule for a Linode.
+
+    name
+        The name (label) of the Linode. Can be used instead of
+        ``linode_id``.
+
+    linode_id
+        The ID of the Linode instance to set the backup schedule for.
+        If provided, will be used as an alternative to ``name`` and
+        reduces the number of API calls to Linode by one. Will be
+        preferred over ``name``.
+
+    auto_enable
+        If ``True``, automatically enable the backup feature for the Linode
+        if it wasn't already enabled. Optional parameter, default to ``False``.
+
+    day
+        Possible values:
+        ``Sunday``, ``Monday``, ``Tuesday``, ``Wednesday``,
+        ``Thursday``, ``Friday``, ``Saturday``
+
+        The day of the week that your Linode's weekly Backup is taken.
+        If not set manually, a day will be chosen for you. Backups are
+        taken every day, but backups taken on this day are preferred
+        when selecting backups to retain for a longer period.
+
+        If not set manually, then when backups are initially enabled,
+        this may come back as ``Scheduling`` until the day is automatically
+        selected.
+
+    window
+        Possible values:
+        ``W0``, ``W2``, ``W4``, ``W6``, ``W8``, ``W10``,
+        ``W12``, ``W14``, ``W16``, ``W18``, ``W20``, ``W22``
+
+        The window in which your backups will be taken, in UTC. A backups
+        window is a two-hour span of time in which the backup may occur.
+
+        For example, ``W10`` indicates that your backups should be taken
+        between 10:00 and 12:00. If you do not choose a backup window, one
+        will be selected for you automatically.
+
+        If not set manually, when backups are initially enabled this may come
+        back as ``Scheduling`` until the window is automatically selected.
+
+    Can be called as an action (which requires a name):
+
+    .. code-block:: bash
+
+        salt-cloud -a set_backup_schedule my-linode-instance day=Monday window=W20 auto_enable=True
