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.

In Dell RecoverPoint, a Consistency Group is built from one or more replication sets. Each replication

set consists of a production volume plus any local or remote copy volumes to which it is replicating1.

Since the mission-critical application is stored on three volumes, and each volume will be part of a

replication set, the Consistency Group for the application will contain three replication sets. This

ensures that all three volumes are protected and replicated as part of the RecoverPoint protection

strategy1.

It’s important to note that the number of replication sets in a Consistency Group is equal to the

number of production volumes being replicated. Therefore, if an application spans multiple volumes,

each volume will be part of its own replication set within the Consistency Group1.

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.

When a VPLEX distributed device is selected during the RecoverPoint Consistency Group Creation

wizard, the option to create a MetroPoint Consistency Group becomes available. This is because

MetroPoint is a feature that leverages VPLEX distributed devices for enhanced data protection and

disaster recovery capabilities. The steps involved in this process typically include:

Selecting the VPLEX distributed device: During the creation of a Consistency Group, you choose the

VPLEX distributed device as the source of replication.

MetroPoint option appears: Once a VPLEX distributed device is selected, the wizard presents the

option to create a MetroPoint Consistency Group.

Configuring the MetroPoint Consistency Group: If you choose to create a MetroPoint Consistency

Group, you will then configure the necessary settings, such as replication mode and RPO (Recovery

Point Objective).

Finalizing the setup: After configuring the settings, you finalize the creation of the Consistency Group,

which now has the enhanced capabilities provided by the MetroPoint feature1.

MetroPoint Consistency Groups are designed to provide continuous data protection and availability

across multiple sites, combining the benefits of VPLEX Metro with the third-site replication provided

by RecoverPoint1.

The Dell EMC RecoverPoint Gen6 appliance contains two slots for I/O modules. For Slot1, the

supported I/O modules are 10-Gb optical fiber and 10-Gb twisted copper pair. This means that Slot1

can accommodate either 10 GbE optical or 10 GbE copper I/O modules1.

The I/O modules are network interface cards with the following characteristics:

10-GB OPTICAL FIBER MODULE: 4 ports, Ethernet network type, supported speed of 10 Gb, wire type

of optical fiber (SFP+).

10-GB TWISTED COPPER PAIR MODULE: 4 ports, Ethernet network type, supported speed of 10 Gb,

wire type of BASE-T twisted copper pair1.

These modules provide the necessary connectivity for the RecoverPoint appliance to manage

replication setup and operations, ensuring efficient data protection and disaster recovery

capabilities1.

:

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.

Questions no: What will be the replication state between the new production and former production

when the administrator selects “Set Copy as Production”?

Verified Answer:

When “Set Copy as Production” is selected, the failover replica copy is confirmed as the new

Production and initiates replication to additional replicas other than the original Production copy

which is already receiving writes after the failover1. This means that the replication state between

the new production and former production would involve initiating replication to the additional

replicas.

Step by Step Comprehensive Detailed Explanation with Reference:

Failover Occurs: The administrator initiates a failover, which involves switching the roles of the

production and non-production copies.

Set Copy as Production: The administrator selects the “Set Copy as Production” option, which

confirms the failover replica copy as the new Production.

Replication Initiated: Replication is initiated to additional replicas, excluding the original Production

copy, which continues to receive writes after the failover.

State of Former Production: The former production copy, now a replica, will be in a state where it is

receiving the replicated data from the new production copy.

This process ensures that the data protection and replication continue seamlessly after the failover,

with the new production copy taking over the role of the source for replication1.

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.

Snapshot Technology: XtremIO arrays use snapshot technology that allows for quick access to data at

a specific point in time.

Logged Access Mode: When using RecoverPoint with XtremIO arrays, Logged Access mode is used

because it leverages the snapshot capabilities of XtremIO.

Instant Promotion: The snapshots created by XtremIO are instantly promoted as the SCSI personality

of the copy, making them immediately accessible to the host.

Efficiency: This process is efficient because it does not require the Journal to roll forward or

backward, which would be necessary for other access modes like Virtual Access.

This capability is part of what makes XtremIO an effective storage solution for environments

requiring rapid access to multiple data points for testing, development, or recovery purposes12.
