// 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."

// Only the interval schedule is currently implemented. Others are ignored.
