To schedule space reclamation on a PowerProtect DD system as specified, here’s the general procedure to follow in the DD System Manager:

Log into DD System Manager: Access the management interface for your PowerProtect DD system.

Navigate to Data Management: In the sidebar, look for an option labeled Data Management or similar (may vary slightly depending on the exact DD OS version).

Select Space Reclamation: Within Data Management, find and select Space Reclamation settings.

Set Schedule:

Click on Schedule and choose to add a new schedule if not already present.

Set the Day to Monday.

Set the Time to 4:00 AM.

Configure Resource Limit:

Look for an option to limit the resource usage for the reclamation task.

Set the Maximum System Resource Usage (or a similarly named option) to 25% to avoid impacting the system performance excessively.

Save the Schedule: Confirm and save your settings.

Verify the Schedule: Check that the schedule appears correctly in the list, indicating it will run every Monday at 4:00 AM with the specified resource usage limit.

After completing these steps, the PowerProtect DD system should reclaim space as scheduled without exceeding 25% resource usage, minimizing its impact on other system operations.
