   Figure 9.3. Recurrence Schedule

   Set Recurrence to the unit of time that you want to use as an interval between snapshots. If you do not want to set up recurring snapshots, leave this field set to None.

   Minutes

   Takes a snapshot every N minutes, where N is the value of the Interval field, with the first snapshot being taken at the time specified in the Start Schedule by field.

   Hours

   Takes a snapshot every N hours, where N is the value of the Interval field, with the first snapshot being taken after the time specified in the Start Schedule by field. Subsequent snapshots will be taken at the start of the hour. For example, if snapshots are to recur every 2 hours, and the first snapshot occurs at 2.20 PM, the next snapshot will occur at 4.00 PM.

   Days

   Takes a snapshot at the time specified in the Execute At field every N days, where N is the value of the Interval field, with the first snapshot being taken after the time specified in the Start Schedule by field.

   Weeks

   Takes a snapshot at the time specified in the Execute At field every N weeks, where N is the value of the Interval field, with the first snapshot being taken after the time specified in the Start Schedule by field.

   Months

   Takes a snapshot at the time specified in the Execute At field every N months, where N is the value of the Interval field, with the first snapshot being taken at the time specified in the Start Schedule by field.

   The End by option determines whether snapshots will stop after a certain date. To set an end date, set End by to Date, and use the fields beside End Schedule By to enter a date and time at which snapshots should stop. To take snapshots continuously with no end date, set End by to No End Date.
