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.

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.

EMC AppSync is the product that integrates with RecoverPoint to provide application-driven point-in-time copies. AppSync simplifies and automates the process of generating and consuming copies of production data.Integrated with EMC storage arrays, AppSync enables application owners to satisfy copy demand for data repurposing, operational recovery, and disaster recovery1.

AppSync allows users to:

Discover application databases or file systems.

Create copies of the data (snapshots, clones, or replicas) that are application-consistent.

Use the copies for various purposes, such as development/testing, reporting, or backup and recovery operations.

Restore from the copies in case of data loss or corruption.

AppSync’s integration with RecoverPoint enhances its capabilities by providing a robust data protection solution that can create point-in-time copies based on specific application events or schedules, ensuring that copies are consistent with the application’s state at that moment1.

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.

When the “Test a Copy” wizard is in progress in a Dell RecoverPoint environment, it temporarily disconnects the local copy from the production and remote copies to allow testing of the data at a specific point in time without affecting the ongoing replication and production operations. The steps involved are:

Initiate Test a Copy: The administrator starts the “Test a Copy” wizard from the RecoverPoint management interface.

Disconnect Local Copy: The wizard disconnects the local copy from the production and remote copies to isolate it for testing.

Perform Testing: The administrator or users perform necessary tests on the local copy, which is now in an isolated state.

Reconnect Local Copy: Once testing is complete, the wizard will reconnect the local copy to resume normal replication and protection operations.

This process ensures that testing can be conducted on a consistent dataset without impacting the production environment or replication processes1.

A MetroPoint Consistency Group is a special type of Consistency Group in Dell RecoverPoint that is designed for environments where high availability and disaster recovery are critical. It includes:

Active Production Copies: These are the primary copies that are actively used in the production environment.

Standby Production Copies: These copies are on standby and can be activated in case the active production copies fail or need to be taken offline for maintenance.

The MetroPoint Consistency Group allows for continuous data protection and availability across multiple sites, combining the benefits of VPLEX Metro with the third-site replication provided by RecoverPoint1.

When using RecoverPoint Unisphere to collect system information, the “Collect System Information” file can be stored on an FTP server that is configured on the RPA cluster. This allows for centralized storage and easy access to the file for further analysis or troubleshooting. The steps typically involve:

Accessing Unisphere: Log into the RecoverPoint Unisphere interface.

Running the Wizard: Navigate to the appropriate section and run the “Collect System Information” wizard.

Choosing Storage Option: Select the option to store the file on an FTP server configured on the RPA cluster.

Retrieving the File: Access the FTP server to retrieve the “Collect System Information” file as needed.

This method ensures that the collected system information is securely stored and can be accessed by authorized personnel for maintenance or support purposes1.

In a Dell EMC RecoverPoint environment, Snap-based replication is supported by the Unity array. This feature leverages the intelligent array-based snapshot capability available in Dell EMC Unity platforms.It enhances asynchronous replication by allowing a user-defined interval for replication, which is particularly useful for environments where minimizing the replication window is critical1.

The Snap and Replicate feature is enabled by leveraging the intelligent array-based snapshot capability available in Dell EMC VNX, XtremIO, and VMAX3/AF platforms as well1.However, for the specific context of the question, which focuses on the EMC array that supports Snap-based replication in a RecoverPoint environment, the correct answer is Unity2.

The priority level of a Consistency Group in Dell RecoverPoint is used to manage bandwidth allocation among multiple CGs that share the same primary RecoverPoint Appliance (RPA). Here’s how it works:

Priority Level Setting: The priority level is set within the CG’s settings, indicating its importance relative to other CGs.

Bandwidth Allocation: The higher the priority level, the more bandwidth is allocated to that CG when bandwidth is limited.

Resource Management: This setting helps ensure that critical CGs receive the necessary resources for replication, especially during peak times or when system resources are constrained.

Replication Efficiency: By managing bandwidth allocation through priority levels, RecoverPoint can maintain efficient replication and meet Recovery Point Objectives (RPOs) for all CGs1.

This feature is particularly important in environments with multiple CGs and limited bandwidth, as it allows administrators to ensure that the most critical data is replicated first1.

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.

When initializing a Consistency Group with a local copy in a RecoverPoint environment, several factors can affect the duration of the process. One possible reason for a longer than expected initialization time is slow performing storage on the production array.If the production storage is not able to handle the I/O operations efficiently, it can lead to delays in the initialization process1.

Another factor to consider is the available bandwidth to the RecoverPoint Appliances (RPAs).Limited WAN bandwidth can also cause delays, but since the scenario mentions a local copy, WAN bandwidth is less likely to be the issue unless the RPAs are also handling remote replication1.

Size mismatch between the production and copy volumes or the copy not being attached to the same splitter as production could also be potential issues, but these would typically prevent initialization from proceeding rather than causing a delay1.

For a detailed diagnosis and resolution, it is recommended to review the system’s performance metrics and logs, and consult the official Dell RecoverPoint documentation or contact Dell EMC support directly1.

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.

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.

When creating a Consistency Group using Unisphere on RecoverPoint/EX, the wizard displays volumes for selection as copy volumes based on specific criteria. The volumes displayed must be masked to the selected cluster and must be the same size or larger than the production volume. This ensures that the copy volume has sufficient capacity to hold all the data from the production volume and any additional data that may be replicated in the future.

The process for selecting the copy volume involves:

Identifying all volumes visible to the selected cluster.

Filtering out volumes that are smaller than the production volume to prevent potential space issues.

Presenting the remaining volumes as options for the administrator to choose as the copy volume.

This approach prevents the accidental selection of a volume that is too small to serve as a copy volume, which could lead to replication issues or data loss.It also allows for flexibility in choosing a larger volume if desired, which can be beneficial in scenarios where future growth is anticipated1.
