- // The DS and FRS use the same structure to represent different schedules.
- // The DS uses a 15-minute polling schedule. FRS uses a 60-minute
- // start/stop schedule. Hence, the schedule for the system volume is
- // a special case because we only have the DS schedule to work from.
- // We will work around this problem by treating the 15
- // -minute polling schedule as a 60-minute start/stop schedule.
- // Replication is enabled for any hour that has any of the four
- // 15-minute bits set.
- //
- // When the ReplicationSchedule is not present the default is
- // "always replicate."
