Calculate Daily Changes: With 100 GB of cumulative changes per day, the total amount of changes over two days would be 200 GB.

Determine Journal Size: The Journal size must be large enough to store all the changes for the required rollback periD.Therefore, a Journal size of 200 GB is necessary.

Set Protection Window: The “Required Protection Window” should be set for 2 days to match the rollback requirement.

Configure Copy Policy: The copy policy should be configured to ensure that the Journal maintains the point-in-time images for at least 48 hours.

By following these steps, the company can ensure maximum protection with the least amount of storage used, while also meeting their rollback requirements1234.

To recover a production volume that has become inaccessible due to logical corruption using RecoverPoint’s “Test a Copy and Recover Production” wizard, follow these steps:

Select a snapshot prior to the corruption: Identify and choose the appropriate point-in-time image from the Journal that was taken before the corruption occurred.

Mount the snapshot to a verification host and verify its integrity: Attach the selected snapshot to a non-production host where you can perform checks to ensure the data is consistent and free from corruption.

Unmount the production volume as the Recovery wizard will overwrite it with the recovery data: Ensure that the current production volume is not in use because the recovery process will overwrite the existing data with the data from the snapshot.

Monitor the progress of recovery from the Unisphere ‘Manage Recovery’ wizard: Use Dell EMC’s Unisphere interface to track the recovery process and ensure that the data is being restored correctly.

These steps are based on the standard procedures outlined in Dell RecoverPoint documentation for using the “Test a Copy and Recover Production” wizard to restore volumes to a previous state1.

In Dell RecoverPoint, a Bookmark is a user-created point-in-time image that can be tied to specific application events. This feature allows users to mark a particular point in time within the continuous data protection timeline of RecoverPoint, which can be used for recovery purposes. Here’s how it works:

User Command: A user issues a command to create a Bookmark, typically through the RecoverPoint management interface or via scripting.

Tied to Application Events: The Bookmark can be associated with specific application events, such as before and after a significant update or batch process.

Point-in-Time Image: The Bookmark represents a point-in-time image of the data at the moment the Bookmark was created.

Recovery: In the event of data corruption or loss, the Bookmark can be used to recover data to the exact state it was in at the time of the Bookmark.

Bookmarks are an integral part of RecoverPoint’s data protection capabilities, providing flexibility and precision for data recovery operations1.

One possible reason for the inability to add an XtremIO source LUN to the Consistency Group in RecoverPoint could be that the XtremIO array was not licensed in RecoverPoint. Licensing is a critical step in enabling the features and functionalities of RecoverPoint for specific storagearrays.If the XtremIO array is not licensed, RecoverPoint would not recognize or allow the addition of its LUNs to a Consistency Group1.

Additionally, it’s important to ensure that the RecoverPoint version supports the XtremIO array model.For instance, RecoverPoint does not support XtremIO X2 arrays until version 5.11. Therefore, if the RecoverPoint version is earlier than 5.1, it would not be able to replicate volumes from an XtremIO X2 array, which could manifest as an issue when trying to add LUNs to a Consistency Group.

For the most accurate and up-to-date information, it is always best to consult the latest official Dell RecoverPoint documentation or contact Dell EMC support directly.

The Dell RecoverPoint documentation recommends a wait period of 7 days before running the Balance Load tool. This period allows for the system to stabilize and for any anomalies in the load distribution to become apparent, ensuring that the Balance Load tool can operate effectively. It’s important to note that this information is based on the best practices outlined in the Dell RecoverPoint documentation and may be subject to change with different versions or specific system configurations.For the most accurate and up-to-date information, it is always best to consult the latest official Dell RecoverPoint documentation or contact Dell EMC support directly1.

The Journal lag in a Dell RecoverPoint system refers to the amount of data that has been written to the production volumes but has not yet been replicated to the remote site or copy volumes. The maximum Journal lag setting affects the RPO because it determines the maximum allowable time or data volume that can pass before the data must be replicated to the remote site to meet the recovery objectives.

Here’s how the Journal lag impacts the RPO:

Journal Lag Definition: Journal lag is the measure of the difference between the most recent write to the production volume and what has been replicated to the copy volume.

RPO Impact: The RPO is the maximum targeted period in which data might be lost from an IT service due to a major incident. If the Journal lag exceeds the maximum setting, itmeans that the RPO could be breached, as there would be more data at risk of being lost than what is acceptable per the RPO policy.

Management Actions: Administrators can monitor and manage the Journal lag to ensure that the RPO is maintained. If the lag approaches the maximum setting, actions may be taken to increase replication throughput or address any issues causing replication delays.

In summary, the maximum Journal lag setting is crucial for ensuring that the RPO is met, as it directly influences the amount of data that could be lost in the event of a failure or disaster1.

When a Consistency Group failover is performed to a remote copy in a Dell RecoverPoint system, the point-in-time images stored in the copy Journal are deleted after the copy becomes the new production.This is because the copy Journal’s role is to maintain a record of changes for recovery purposes, and once the copy is promoted to production, its Journal is reset to start recording new changes from that point forward1.

The process involves the following steps:

Failover Initiated: The administrator initiates a failover to the remote copy.

Copy Becomes Production: The remote copy is promoted to the production role.

Journal Reset: The point-in-time images in the copy Journal are deleted as part of the promotion process.

New Production Journal: A new production Journal is started to record changes from the new production copy moving forward.

This ensures that the RecoverPoint system can continue to protect the data with a fresh start for the new production environment1.

To identify whether physical or virtual RPAs are in use on a specific cluster using Unisphere for RecoverPoint, follow these steps:

Navigate to RPA Clusters: In Unisphere, locate and click on the ‘RPA clusters’ section.

Select Cluster Name: Find and select the specific cluster you want to investigate.

View RPA Details: Click on the ‘RPAs’ option to view detailed information about the RPAs associated with the selected cluster.

This process will provide you with the necessary information to determine the type of RPAs (physical or virtual) that are being used within the specified cluster1.

To integrate Site Recovery Manager (SRM) with RecoverPoint, the storage replication adapter is a critical component that allows SRM to manage RecoverPoint replication properly. The installation steps are as follows:

Identify SRM Servers: Determine which servers are running the VMware Site Recovery Manager service.

Install SRA: Install the RecoverPoint SRA on each of the SRM server hosts at both the recovery and protected sites.

Verify Installation: Ensure that the SRA is correctly installed and recognized by the SRM service.

Configure Replication: Use the SRA within SRM to configure and manage replication settings for disaster recovery.

It’s important to use the most current version of the SRA to ensure optimal compatibility and available features.The SRA can be downloaded from the VMware website, and the SRA release notes and product documentation should be consulted to determine compatibility with SRM versions1.

In a Dell RecoverPoint system with XtremIO arrays at both production and disaster recovery sites, setting the replication mode for a Consistency Group as “Continuous” implies that the replication occurs continuously without predefined intervals. This mode aims to minimize the Recovery Point Objective (RPO), which is the maximum targeted period in which data might be lost due to a major incident. While an RPO of 0 seconds is ideal, it is often not practical due to network latency and system processing times.Therefore, an effective RPO of less than 60 seconds is a realistic target for a “Continuous” replication mode, ensuring that data loss is minimized to the lowest possible timeframe in the event of a disaster1.

RecoverPoint Write Phase:

In the RecoverPoint replication process, the write splitter plays a crucial role in intercepting writes from the host and forwarding them to both the production storage and the RecoverPoint appliances (RPAs).

Write Splitter Functionality:

The write splitter intercepts write I/O requests from the host and splits the I/O to both the production LUN and the RPAs. This ensures that the data is written to both the primary storage and replicated copies.

Acknowledgement Process:

During the write phase, the write splitter must ensure that the data is successfully written to the production LUN before acknowledging the write request back to the host.

This is because the primary concern is ensuring data integrity and confirming that the data is safely stored in the production environment before any replication considerations.

Detailed Workflow:

Step 1: Host issues a write request.

Step 2: The write splitter intercepts the write request.

Step 3: The write splitter forwards the write to the production LUN and the RPAs.

Step 4: The production LUN processes the write and sends an acknowledgement back to the write splitter.

Step 5: Upon receiving the acknowledgement from the production LUN, the write splitter then sends an acknowledgement back to the host.

When the database team’s write activity is expected to exceed the space allocated for Image Access mode in RecoverPoint, additional Journal volumes need to be added to accommodate the increased write activity. This can be done through the Unisphere for RecoverPoint interface:

Navigate to Protection: Access the Protection menu in the Unisphere for RecoverPoint.

Manage Protection: Go to the Manage Protection section.

Select the Consistency Group (CG): Choose the appropriate CG from the list.

Select the Copy: Click on the copy that is being used for the Point-in-Time (PIT) testing.

Edit Journal: Click on the Edit Journal option.

Add Journal Volumes: Add one or more additional Journal volumes to ensure there is enough space for the write activity during the testing periD.

By adding additional Journal volumes, the database team can continue their testing without disruption due to space limitations in the Image Access mode1.

When using the CLI to create a new Consistency Group in RecoverPoint, after initiating the process with the create_group command, the next step involves adding volumes to the group. The add_replication_volume command is used to add a volume to a Consistency Group as a replication volume.This command specifies the volume to be replicated and associates it with the newly created group1.

The sequence of commands would typically follow this pattern:

Run create_group to initiate the creation of a new Consistency Group.

Run add_replication_volume to add each production volume that needs to be replicated within the Consistency Group.

Additional commands would follow to configure the properties of the Consistency Group and its replication sets1.

It’s important to note that the add_group_set command is used for different purposes, such as grouping multiple Consistency Groups together, and the create_replication_volume and create_production_copy commands are not standard commands in the RecoverPoint CLI for this context1.

When using the automatic journal provisioning feature in RecoverPoint, the system requires dedicated resource pools to be set up.These resource pools are predefined storage resources that RecoverPoint can utilize to automatically create and allocate Journal volumes as needed when adding a Consistency Group1.

The process for setting up automatic journal provisioning typically involves:

Creating Resource Pools: The administrator defines resource pools within the storage array, dedicating specific storage resources for RecoverPoint’s use.

Configuring RecoverPoint: Within the RecoverPoint configuration, the administrator specifies that these resource pools are to be used for automatic journal provisioning.

Adding a Consistency Group: When a new Consistency Group is added, RecoverPoint automatically provisions Journal volumes from the dedicated resource pools without manual intervention by the administrator.

Monitoring and Managing Journals: The administrator can monitor the automatically provisioned Journals and manage them as necessary through the RecoverPoint management interface.

This feature streamlines the process of setting up and managing Journal volumes, making it more efficient and less prone to human error1.

When setting up replication for a Consistency Group between clusters using XtremIO storage arrays at each site connected through Fibre Channel, the maximum throughput that can be expected per RecoverPoint Appliance (RPA) is 300 MB/s. This throughput is a measure of how much data can be transferred from one site to another per second by each RPA involved in the replication process.

The throughput capacity is important for planning and ensuring that the RecoverPoint system can handle the expected data load during replication activities. It affects the Recovery Point Objective (RPO) and the overall efficiency of the disaster recovery setup.The 300 MB/s figure provides a benchmark for administrators to gauge the performance capabilities of their RecoverPoint system when used in conjunction with XtremIO storage arrays1.

It’s important to note that actual throughput can vary based on several factors, including network conditions, the amount of data being replicated, and the specific configuration of the RecoverPoint and XtremIO systems1.

The performance of the Journal volumes at the remote copy can significantly affect the time it takes for a Consistency Group to complete the first-time initialization. The Journal volumes are where all the changes to the protected volumes are recorded before they are replicated to the remote site.If the Journal volumes are performing poorly, due to issues like high latency or low IOPS (Input/Output Operations Per Second), it can slow down the initialization process as the system struggles to record and replicate the data efficiently1.

Other factors such as the distance between the production and remote copy clusters and the number of RecoverPoint Appliances (RPAs) at both the production and remote copy clusters can also influence the initialization time. However, these factors typically affect the ongoing replication performance rather than the initial synchronization.The number of RPAs can impact the system’s ability to process and replicate data, but the most direct impact on initialization time is the performance of the Journal volumes, as they are the bottleneck in the data recording process1.

For the most accurate and up-to-date information, it is always best to consult the latest official Dell RecoverPoint documentation or contact Dell EMC support directly1.

For Distributed Consistency Groups in a Dell RecoverPoint environment, the minimum size required for each journal volume is 40 GB.This is the minimum per copy, which can be a single LUN or multiple LUNs that add up to at least 40 GB1.

The size of the journal is determined by the write change rate of what is being replicated and the protection window required per Consistency Group. A general rule of thumb is about 15-20% of the total amount of data being replicated.For example, if a Distributed Consistency Group (DCG) has production server LUNs totaling 500 GB, then the journal per copy would be about 100 GB following this rule1.

It’s important to note that while 40 GB is the minimum, the actual size may need to be larger depending on the specific requirements and write change rate of the environment.The journal size should be sufficient to handle the data changes and provide the necessary protection window1.
