Suppose that you have several file servers, whose volumes fit into three general classes:

  • Class A stores users’ home directories. The data in this class changes at a rapid rate throughout the day.

  • Class B stores shares for organizational units within the company. The data in this class changes at a slow rate throughout the day.

  • Class C stores only sets of data exported by scripts that run once each night. Because the scripts run just once daily, the data in this class changes only once each day.

In this case, you might organize your protection groups as follows:

  • For Class A, create Protection Group X, and specify a protection schedule composed of an hourly synchronization schedule and a shadow copy schedule consisting of four snapshots spaced evenly across business hours.

  • For Class B, create Protection Group Y, and specify a protection schedule composed of an hourly synchronization schedule and a shadow copy schedule consisting of two snapshots spaced evenly across business hours.

  • For Volume C, create Protection Group Z, and specify a protection schedule composed of one scheduled shadow copy each day, immediately preceded by one synchronization job.
