BoostFS allows applications without native DD Boost support to leverage DD Boost's deduplication benefits. It provides a seamless data protection layer across various backup applications by streamlining storage and data transfer processes. BoostFS, or Boost File System, is used to enable backup functionality for applications that do not natively support DD Boost. It allows these applications to leverage Data Domain storage efficiency by providing a file system interface. BoostFS essentially provides a method for applications without DD Boost integration to still utilize deduplication and other Data Domain benefits, making it highly effective for environments that want to standardize their storage approach but have a mix of applications with and without DD Boost support.

PowerProtect DD High Availability configurations are supported on the DD9900 model with a single set of shared storage, ensuring redundancy and failover capabilities, critical for enterprise-level data protection environments.

PowerProtect DD High Availability (HA) configuration provides a continuous availability solution, particularly suited for DD9900 systems. Here are the two key attributes of DD HA:

Single Set of Shared Storage: In the HA configuration, both nodes in the active/standby configuration share the same set of storage. This shared storage ensures that if the active node fails, the standby node can take over without data loss, accessing the same storage seamlessly.

Supported Only on DD9900 Systems: The HA feature is exclusive to high-end PowerProtect DD models, specifically the DD9900. This limitation is due to the hardware requirements needed to support the robust failover and data redundancy capabilities inherent in an HA setup.

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.

A small TCP window size can restrict data throughput, leading to suboptimal performance in CIFS-based file transfers. Adjusting the TCP window size can help maximize network bandwidth utilization and improve transfer speeds.

The ddboost storage-unit create <storage_unit> command is used to create a storage unit specifically for DD Boost-enabled backups, facilitating direct backup operations with PowerProtect DD.
