Solution This solution provides the following: Point-In-Time Recovery • RecoverPoint provides continuous data protection with multiple recovery points to restore applications instantly to a specific point in time. Continuous Replication • Protected applications with bidirectional synchronous and asynchronous replication in a physical virtual and cloud infrastructures. Simplified Testing • Streamline disaster recovery testing of your application environment while production replication continues unaffected. RecoverPoint integrates with vCenter Server to allow the RecoverPoint administrator to quickly view virtual machines fully protected by RecoverPoint, and to see which of the virtual machine’s LUNs/data stores are not protected. Additionally, RecoverPoint is integrated with VMware Site Recovery Manager (SRM) to simplify and automate disaster recovery failover and failback in VMware Infrastructure. VMware vCenter SRM automates the recovery process so it becomes as simple as pressing a single button. There is no need for you to interact with the RecoverPoint console and the VMware console: instead VMware automates the process. All you have to do is ensure that the production virtual machines are mapped to LUNs that are replicated by RecoverPoint to the remote site.

Ease of Integration, Comprehensive Features RecoverPoint Overview EMC RecoverPoint is a comprehensive data protection solution that provides integrated CRR and CDP, with bidirectional synchronous and asynchronous replication. RecoverPoint offers Fan-out where the same data can be protected to up-to 4 remote locations hence enabling businesses to achieve regulatory compliance and flexibility with various operational scenarios. RecoverPoint offers 4:1 Fan-in as well, where various data can be protected back to a centralized Disaster Recovery site. RecoverPoint allows users to recover applications Locally or Remotely to any point in time without impact to the production application or to ongoing replication. RecoverPoint offers heterogeneous replication with bandwidth efficiencies in IP or Fiber Channel synchronous or asynchronous replication environments, which lowers your multi-year total cost of ownership. RecoverPoint CDP enables you to roll back to any point in time for effective local recovery from events such as database corruption. RecoverPoint integrates with VMWARE Site Recovery Manager and enables point-in-time granularity for SRM environments through the use of it Virtual Storage Integrator (VSI). RecoverPoint is appliance-based, and it comes in a physical form or a virtual form (Virtual Machine) which enables it to better integrate in various environments and protect information stored across heterogeneous servers and storage environments. RecoverPoint uses lightweight splitting technology in the Symmetrix VMAX, Clariion VNX , and VPLEX to mirror a write to a RecoverPoint appliance that resides outside of the primary data path. Implementing this approach enables RecoverPoint to deliver continuous replication without impacting an application’s I/O operations.

Lab Scenario RainPole has a critical application protected with RecoverPoint and RainPole's management has set a requirement to be able to recover this application using the Local copy or Remote copies. In the first part of this lab you will assume that an upgrade to the system goes wrong and you're required to restore the application using the Local copy. The second part of this lab will involve simulating a hardware failure to the production server and you'll be required to perform a failover to the remote site where a stand by host will continue to run the application.

Return to Unisphere for RecoverPoint Return to the Unisphere for RecoverPoint interface and navigate to the Lab_2_Operational Recovery Consistency Group if you're not there already. Validate that both links are in Active state. Next we will create a Bookmark, by clicking on the Bookmark button at the bottom of the Status pane.
Create a Pre-Upgrade Bookmark A bookmark is simply a labeled point-in-time image. Typically bookmarks are taken before upgrades, patches, data structure changes and during quiesced state of the application. Every point-in-time image is Crash-Consistent Crash-Consistent. Bookmarks can be either crash-consistent if taken while the application is running or Application-Consistent if taken while the application is quiesced. In this scenario, you have worked with the database team who are planning a major data restructure and they have asked you to take a bookmark before they start their data restructure process. Enter a name for the bookmark, type Before_Upgrade
Operational & Disaster Recovery using RecoverPoint
Page 68
Assuming the Bookmark was taken while the application was online, choose Crash-Consistent and click OK
Validate Bookmark Expand the Lab_2_Operational Recovery Consistency Group and select the CDP copy. Next select the Journal tab and validate that the bookmark which you've created in the previous step is in the CDP journal. By clicking on "Bookmark" at the top of the bookmark column you can sort by any named bookmarks. This can help you locate your bookmark faster.
Operational & Disaster Recovery using RecoverPoint
Page 69
Data Corruption at Production After you have taken the bookmark, the database upgrade starts but unfortunately the Database Administrator updates the wrong table causing the application to break. RainPole management decides that they need to recover the database to a point pre-upgrade. Fortunately, RainPole has protected this database with RecoverPoint and have the ability to recover using many available images both locally and remotely. Once you get a request that the database team want the database to be restored, you quickly realize that the Local Copy is the best approach. You present the CDP copy to the Linux machine, verify the data and then restore production. Now, to simulate the data corruption, return to the Linux server window. Let's add some text to the file named file2 using the echo command. We then use the cat command to verify the text in the file. Enter the following command at the prompt to add text to to the file: echo "Wrong Data" >> file2 cat file2 Verify your output matches the example above. Oh no! We knew it! The database team didn't want that data in file2! The database need to be restored.
Unmount File System We now have few options: 1. We can perform Test a Copy (enable image) using the bookmark we took prior to the upgrade, mount the CDP copy on the local host and have the DBAs copy the file over from an alternate host or alternate file system to the prod file system
Operational & Disaster Recovery using RecoverPoint
Page 70
2. We can Enable Image Access, validate the data and then perform a restore or recovery from the CDP copy back to production 3. Use the bookmark and perform Recovery. Since you have verified the bookmark, you felt confident that it contains the data as it was prior to the upgrade, you choose option #3. To recover the corrupted file system, remove host's access to it. cd / umount /data
Let's go back to Unisphere for RecoverPoint and recover production

Recover from Remote Copy After successfully recovering from corruption using the Local (CDP) copy, you're now being faced with a different scenario. In this scenario, the Linux production server in Cork encounters a hardware failure and requires repair, so RainPole management asks you to failover the application from Cork to New York where there is a target server that can run the application. This time we will use the Fail Over wizard under the Recovery tab.
Connect to VC01 (Cork) To simulate the hardware failure of the production Linux server vm01 vm01, we will log-in to VC01 and poweroff the server. Locate the VMware vSphere Client VC01 shortcut on the desktop and double click.

Summary You have successfully managed to protect a critical application from 2 different disasters. In the first one, you were able to quickly utilize RecoverPoint Local copy to restore the application to a pre-upgrade stage without losing any data. In the second scenario a hardware failure was encountered at the primary site, and by using RecoverPoint Remote copy you were able to select the best point-in-time image to run production at the remote site and then failback once the production server has been repaired. RianPole management could not be happier!

Lab 3 - Disaster Recovery using RecoverPoint with VMware Site Recovery Manager
Operational & Disaster Recovery using RecoverPoint
Page 97
Lab Scenario RainPole has a critical Active Directory and SQL database protected using RecoverPoint. You're using Site Recovery Manager with SRA and the new EMC Virtual Storage Integrator (VSI) to manage the environment. The application team has scheduled a major upgrade of the SQL database, however; they run into an issue during the upgrade that requires them to recover back to a point prior to the start of the upgrade. Given your expertise and the fact that you have RecoverPoint, you feel very confident that you're able to recover the application to any point in time in. In this exercise you will use SRM to conduct a Recovery operation using a specific point-in-time to the Remote site and then perform a failback but first we will review the setup of the Consistency Group and the SRM configuration.
Please Note: As this lab environment is fully virtualized there may be delays in the readiness of Lab 3 when it is first made available. In this instance it is recomended to perform lab 1 or 2 while lab 3 is in a initializing state.

VSI Plugin As part of RainPoles disaster Recovery plan they would like to able to failover to a predefined point in time. The new EMC VSI plugin enables SRM to take advantage of RecoverPoint's point-in-time images hence allowing you to perform Recovery operations to any point-in-time snapshot or bookmark as we will see later on in this lab. As part of this process you will first view the plugin and the details it needs to be able to provide this capability.

SRM Recovery using RecoverPoint and the new EMC VSI The database team is about to begin the upgrade process and they have asked you to take a bookmark of the environment. We first add some text to help us track the status of the database SQL server and then we take a bookmark which can be used in the SRM Recovery. This bookmark is a cautionary step and not needed as the EMC VSI plugin will give you access to all point-in-time images. However, taking a bookmark will help you locate the exact point-in-time that you need to recover to in case anything goes wrong during the upgrade. Locate a shortcut to Putty on the desktop, we will use it later on to access the command line for RecoverPoint and create a bookmark.
Access the SQL Server in Cork We will first RDP into the production SQL server(shown below) using mRemote and then create some data to indicate a pre-upgrade point-in-time. We will then take a RecoverPoint bookmark which will be used later on in the EMC VSI and SRM Recovery

Create a Pre-Upgrade Bookmark A bookmark is simply a labeled point-in-time image. Typically bookmarks are taken before upgrades, patches, data structure changes and during quiesced state of the application. Every point-in-time image is Crash-Consistent (please note that due to the version of code used in building the lab, the Crash-Consistent is listed as Unknown). Bookmarks can be either crash-consistent if taken while the application is running or Application-Consistent if taken while the application is quiesced. In this scenario, you have worked with the database team who're planning a major data restructure and they have asked you to take a bookmark before they start their data restructure process. To take a bookmark, execute the following command: bookmark_image
Operational & Disaster Recovery using RecoverPoint
Page 124
You will then be asked to specify a Consistency Group for the bookmark, enter Lab_3 Disaster Recovery with SRM. Please note that you can tab and the CLI will auto-complete the name of the Consistency Group Enter a name for the bookmark, type Before_Upgrade Select default policy for journal consolidation which is always. Journal Consolidation policies are user defined policies that allow for longer retention of images without requiring additional journal space. Assuming the Bookmark was taken while the application was online, choose Crash-Consistent (Unknown) and press Enter to continue. Validate that the bookmark_image command was successful; the system should display Request for bookmark registered successfully message indicating successful execution of the command.
Validate Bookmark If you would like to validate that the bookmark has been created in the copy journal. You can execute the get_images command Enter Lab_3 Disaster Recovery with SRM for the group name Then specify a copy name New York CRR
Operational & Disaster Recovery using RecoverPoint

Leave the default for the remaining 3 questions and the list of available images will be displayed. Validate that the bookmark we just created Before_Upgrade is there.
Operational & Disaster Recovery using RecoverPoint
Page 126
Data Corruption at Production After you have taken the bookmark, the database upgrade starts but unfortunately the Database Administrator updates the wrong table causing the application to crash. RainPole management decides that they need to failover to the remote site and use a point in time just before the upgrade had started. Fortunately, RainPole has protected this database with RecoverPoint and have implemented Site Recovery Manager with the new EMC VSI which enables SRM to access any available image. Now, to simulate the data corruption, return to the SQL server RDP session in mremote. Let's add some text to the file named SQL Status to indicate data corruption. Let us simply add: Wrong Data and then make sure to save the file You might want to close and reopen the file to make sure the Wrong Data text has been saved. Now the application is down and we need to rollback to a pre-upgrade state.
