Select MTree from the dropdown menu to manage MTrees.

Step 2: Create a New MTree

Click on Create MTree or Add MTree (the exact button label may vary).

Set the Path for the MTree as /data/col1/oracle.

Step 3: Set the MTree Size Limit

In the MTree creation dialog, look for an option to set a Quota or Size Limit for the MTree.

Set the Size Limit to 200 TiB to ensure the MTree does not exceed this capacity.

Step 4: Save the Configuration

The maximum backup speed of the PowerProtect DD Virtual Edition (DDVE) when utilizing DD Boost is 4.2TB per hour. DD Boost is a feature that enhances the speed and efficiency of data transfers between the backup application and the Data Domain appliance by performing deduplication operations closer to the source, thus reducing network traffic and improving throughput. DDVE’s performance capabilities are optimized for virtualized environments, and the 4.2TB/h rate represents the upper limit under ideal conditions, maximizing data protection performance in virtual setups.

1. Writes request from the backup software

First, the backup software sends a write request to the DD system.

2. Analyzes data for redundancy and stores new data segments

Next, DDOS analyzes the incoming data for redundancy and stores only the unique data segments to optimize storage.

3. Stores the fingerprints

After deduplication, the system stores the unique fingerprints of the data.

4. Verifies that the checksum that is read back matches the checksum that is written to the disk

This step involves verifying the data integrity by matching the written checksum with the read checksum.

5. Verifies that DDOS can read data from the disk

Finally, the system verifies that the data can be read back correctly from the disk, ensuring the write was successful.

Explanation: Enabling the security-officer authorization policy activates the dual authorization process, adding a layer of security by requiring approvals for certain actions. This feature is critical for environments with strict compliance and data governance requirements.
