The default frequency is weekly (168 hours), which is suitable for most

NOTE: We recommend that you leave the patrol read frequency and other patrol read
settings at the default values to achieve the best system performance. If you decide to
change the values, record the original default value here so you can restore them later,
if necessary:
Patrol Read Frequency: ___________________
Continuous Patrolling: Enabled/Disabled
Patrol Read Task Rate: ___________________
7. (Optional) Set Patrol Read to run at a specific time.
