EMC RecoverPoint for Virtual Machines Administrator’s Guide 3
RecoverPoint for Virtual Machines
RecoverPoint for Virtual Machines enables local or remote replication allowing recovery to
any point in time. RecoverPoint for VMs consists of a VMware® vSphere Web Client
plug-in, a RecoverPoint write-splitter embedded in the ESXi hypervisor, and a virtual
appliance, integrated in the VMware ESXi server environment.
You should be familiar with the following terms and concepts:
◆ RecoverPoint for VMs splitter: The RecoverPoint for VMs splitter is proprietary software
installed on every ESXi server in an ESXi cluster involved in RecoverPoint replication
or running virtual RPAs. The RecoverPoint for VMs splitter splits every write to the
VMDK and sends it first to the vRPA.
◆ Virtual RecoverPoint appliance: The virtual RecoverPoint appliance (vRPA) is a virtual
data appliance that manages all aspects of data replication.
◆vRPA cluster:
A vRPA cluster is a group of 2-8 vRPAs that work together to replicate and
protect data. There are one or two clusters in a RecoverPoint for VMs system; onecluster is used for local replication and two are used for remote replication. To
scale-up and support a higher throughput rate, you can have up to eight vRPAs in your
clusters.
◆ RecoverPoint for VMs system: A RecoverPoint for VMs system includes all
RecoverPoint for VMs components at all clusters in one installation.
vSphere Web Client Plug in: The RecoverPoint for VMs plug-in within the vSphere Web
Client. This is the user interface for managing VM replication. Access the vSphere Web
Client at: https:// : /vsphere-client/
Where is the IP address of the vCenter and is the port selected in
the installation of the web client plug-in. The default port is 9443.
RecoverPoint replication
The following logical entities constitute the replication environment:
◆ Consistency groups: A consistency group is a container for virtual machines and all
their copies whose application data needs to be replicated to a consistent point in
time. For instance, if you replicate a database and its transaction log, you need both
files, and you always need both files to be at the exact same point in time. You can
achieve this by placing the virtual machine running the database and the virtual
machine running the transaction log in one consistency group or in one group set. The
consistency group comprises virtual machines, their copies, and their journals.
◆ Copies: In RecoverPoint for VMs, a copy is an image of a virtual machine and its
application data accessible at a vRPA cluster.The application data is immediately
usable. The following types of copies exist:
• Production copy: The production copy consists of all of the virtual machines with
their application data that are the source for replication (that is, protected by
RecoverPoint).

RecoverPoint for Virtual Machines
•Local copy:
A local copy is a copy of production virtual machines with their
application data that is accessible on the vRPA cluster running production. The
local copy is used for continuous data protection, such as recovering from logical
errors and data corruption. A virtual machine that is replicated to a local copy is
identified by the .copy extension at the end of the virtual machine name.
• Remote copy: A remote copy is a copy of production virtual machines with theirapplication data that is accessible on a remote vRPA cluster. ( Remote denotes
clusters that are connected only by WAN.) The remote copy is used for disaster
recovery. A virtual machine that is replicated to a remote copy is identified by the
.copy
extension at the end of the virtual machine name.
◆ Shadow VM: For internal RecoverPoint use only. A shadow VM is identified by the
period at the front of the virtual machine name and the .recoverpoint extension at the
end of the virtual machine name.
◆Journals:
Each copy of a consistency group must contain a resource pool that is
dedicated to holding marking information or point-in-time history.
• Production journal: Production journals store information about the replicationprocess that makes synchronization between the production and copies more
efficient. After failing over, the production journal becomes a copy journal.
• Copy journal: The copy journal receives successive writes written to production.
Since the write-order is maintained, it is possible to apply or undo writes so that
the copy image can reflect any point in time.
◆ Snapshot: A snapshot is the difference between one consistent image of stored data
and the next. Snapshots are stored in the copy journal.
◆ Snapshot consolidation: A process that consolidates the data of multiple snapshots
into a single snapshot to allow a longer history to be retained in the journal.
Automatic snapshot consolidation settings can be specified in the copy protectionpolicy.
◆ Bookmark: A bookmark is a manual snapshot with a label you apply to it to identify it.
Parallel bookmarks are bookmarks with the same name applied at the same time to
multiple consistency groups in a group set.
◆ Group set: A group set is a collection of consistency groups to which the system
applies parallel bookmarks at a user-defined frequency. Group sets are useful for
consistency groups that are dependent on one another or that must work together as
a single unit.
◆ Link: A link is the communication connection between RecoverPoint copies. When the
link is open, data can be transferred between copies.
RecoverPoint for VMs protection
The following concepts are integral in RecoverPoint for VMs protection and recovery:
◆ Protection: Protection is the replication of a VM to a copy by adding it to a consistency
group. Protection can be used to recover from logical data corruption by selecting a
point in time before the corruption; or from a physical disaster by failing over to the
copy.
-

RecoverPoint for Virtual Machines
EMC RecoverPoint for Virtual Machines Administrator’s Guide 5
◆ Protection policies: RecoverPoint protection is policy-driven. A protection policy is
uniquely specified for each consistency group, copy, and link and defines how
replication is carried out. The protection settings defined in the policy will affect how
replication behavior changes depending on the level of system activity and the
availability of network resources.
◆Policy templates: Policy templates are defined protection policies that are saved andcan be reused. Three default policy templates are included in RecoverPoint for VMs:
Default local link; default remote link; default copy.
◆ Image access: Image access mode allows you read/write-access to a selected point in
time at a copy. Image access mode is used to test a copy to verify that it is a reliable
and consistent replica of production. It is also the first step in restoring production
from the copy, rolling back to a previous point in time, recovering data, and failing
over to the copy.
◆Failover and disaster recovery:
Failing over a consistency group to a local or remote
copy sets that copy to be the production and the original production becomes the
copy. Failing over to a copy can be used to recover from a disaster at the production
site and allows system operations to continue from the copy. Failing over erases the
copy journal. During failover, transfer is paused and access to the original production
is blocked. System operations can be resumed at the original production source by
failing back.
◆ Recovering production: Recovering production restores the production from the copy
at the selected point in time.
◆ Initialization: Initialization is the RecoverPoint process used to synchronize the data of
the copy VMs with their corresponding production VMs to ensure consistency. A full
sweep is an initialization that is performed on all of the VMs in a consistency group. A
full sweep initialization occurs when a consistency group is created. Full sweeps are
also required when you enable a disabled consistency group and when there isproduction journal loss.
Supported VMware actions
◆ vMotion:
• Host and Storage vMotion are supported.
• Applies to both vRPAs and protected VMs.
◆ Memory and CPU changes to protected VMs are allowed:
• These changes are not replicated.
• You can manually adjust resources on copy VMs.
◆ VMDK source insertion:
• RecoverPoint for VMs auto-provisions VMDK at the copy VM and adds it to
consistency group as a new replication set.
• The journal history is deleted and a volume sweep is performed.
◆ VMDK source removal:
• VMDK is not removed from the copy VM to protect against accidental removal.
◆ Source VM deletion:
• When the RecoverPoint for VMs detects a deletion of a VM, it recognizes it as a
disaster for all relevant VMDKs which were lost.
• The copy VM remains intact.

RecoverPoint for Virtual Machines
◆ Target VMDK deletion:
• When a copy VMDK is removed, RecoverPoint for VMs recreates the VMDK.
• The journal history is deleted and a volume sweep is performed.
◆ Taking VMware snapshots is supported only on production virtual machines and not
on copy virtual machines. Using the VM Restore operation to restore a production
virtual machine from a VMware snapshot or clone will cause a full sweep.
◆ Promoting VMware snapshots on the copy VM is highly unrecommended.
◆ Replicating a virtual machine with fault tolerance enabled is not supported.
◆ Changing the configuration of virtual machines that are being replicated is not
supported, except changing network connections, which is supported.
◆ To clone a copy VM, it must be powered off. If it is not powered off, a VMware snapshot
will be created, which causes permanent data corruption.
◆ vCenter in Linked Mode is not supported.
◆ The resources (memory and CPU) of a running vRPA can be increased but not
decreased. The changes will take effect only when the vRPA is rebooted.
◆ Any suspend or resume tasks (or hibernation-like functionality) of a running vRPA
virtual machine is not supported and will lead to data corruption or failure.
◆ Collecting vSphere logs from a running vRPA (for instance, using vSphere File > Export >
Export System Logs command) may cause inconsistencies in the datastore or other
unexpected behavior.
◆ Before creating a VMware snapshot of a vRPA, it must be detached from the vRPA
cluster.
◆ Upgrading VMware tools on the vRPAs is strictly unsupported and may lead to
undesired results.
◆ Any online or offline porting of vRPA is supported without affecting high availability,
except for suspend or resume operations, which can lead to corruption (especially if
the vRPA is the cluster leader for the consistency groups).

RecoverPoint for VMs protection
Use the procedures in this chapter to set up your RecoverPoint for VMs system and start
protecting VMs.
Licensing your system
Once your RecoverPoint for VMs sales order is approved, a LAC (License Authorization
Code) is automatically sent to the email addresses provided during order entry,
containing all of the customer’s entitlements. Each entitlement must be activated and
then saved as a license file before it can be added to the RecoverPoint system.
Before you begin, note the following:
◆ Licenses can be partially activated or fully activated.
◆ Licensing is enforced per vRPA cluster, using the RPA cluster ID.
◆ When reaching license limit, users will not be able to protect new VMs. but replicationof existing VMs will continue.
To license RecoverPoint for VMs:
1. Access your entitlements on emc.support.com:
• If you have your LAC email, open it and click the Click here link to automatically
access Powerlink Licensing on the EMC Online Support site, and search for the
entitlements associated with the LAC.
• If you do not have your LAC email but you do have your LACs or sales order
numbers, log into the EMC Online support at http://support.emc.com, and:
a. Select Support > Service Center from the main menu
b. Select Get and Manage Licenses
c. Select RecoverPoint for Virtual Machines
d. Enter the customer's LAC and click Activate to search for all inactive
entitlements associated with a customer's profile or access all of the features
of the Licensing site by clicking Manage Entitlements. Whichever option you
chose, the Search Entitlements to Activate screen is displayed.
2. Activate your entitlement(s) and download your license file(s).
The Search Entitlements to Activate screen is the first screen of a five screen wizard
that will guide you, step-by-step, through the process of turning your LACs into license
files (redeeming the entitlements). In this screen:
a. Select an entitlement to activate. Each entitlement must be selected and activated
separately.
b. Click Start Activation Process.
c. In the Search Machines dialog box, click Add a Machine.

RecoverPoint for VMs protection
d. In theAdd Machine
dialog box, enter a new machine name, and clickSave
.
Note: A machine name is like a folder, it is used to group items together logically. A
unique machine name must be specified for each entitlement.
e. In the Register screen, verify the machine name, and click Next.
f. In the Activate screen, enter the Locking ID, and click Next.
Note:
TheLocking ID
is the field that is displayed under theMachine Information
column; its value is the entity the license is enforced to, namely, the RPA Cluster ID.
To find the RPA Cluster ID value, create an SSH connection to the cluster
management IP, log in as an admin user (user: admin password: admin ), and run
the get_internal_cluster_uids command or call EMC Licensing support.
g. In the Confirm screen, enter the email addresse(s) of the recipients of the license
file in the Email to field of the Additional Email Options section, and click Finish.
Separate multiple email addresses with commas.
h. In the Complete screen, click Save to File to download the license file and save the
file locally. The resulting license file has a *.lic extension and is in plain text format
(can be opened in any text editor).
i. Redo this procedure for all inactive entitlement in each LAC email.
3. After you have turned all of your entitlements into license files, physically transfer the
license file(s) to the computer from which you will be running RecoverPoint for VMs.
4. Install your license file(s) in RecoverPoint for VMs:
a. In the vSphere Web Client home page, click the RecoverPoint for VMs Management
icon > Administration tab > Licenses tab.
b. Select the vRPA cluster to which you wish to add a license. Click Add.
c. In theAdd license
dialog box, enter the location of the license file or clickBrowse
to locate the file. Click OK.
Enabling support
To enable support, configure the system reports and alerts mechanism (SyR) to provide
communication between your RecoverPoint for VMs system and the EMC System Reports
database (ESRS).
Before you configure system reports or alerts, note the following:
◆ To send system reports and alerts, a permanent RecoverPoint license must exist in the
system; system reports and alerts will not work with a temporary license.
◆ Best practice is to keep both system reports and alerts, and compression and
encryption enabled.
◆ System reports and alerts will only be sent provided a valid method of transfer (SMTP,
ESRS, or FTPS) is configured.
◆ ESRS is the recommended method of transfer.

EMC RecoverPoint for Virtual Machines Administrator’s Guide 9
◆ To transfer system reports and alerts using SMTP or ESRS, ensure that port 25 is open
and available for SMTP traffic.
◆ To transfer system reports and alerts using FTPS, ensure that ports 990 and 989 are
open and available for FTPS traffic.
To configure system reports and alerts:1. Create an SSH connection to the floating management IP of your RecoverPoint for VMs
system and log in with your RecoverPoint username (default is admin ) and password
(default is admin ).
2. Run the set_smtp_server command and define the IP address of your SMTP sever.
3. Run the config_system_reports command. Ensure that system reports and system
alerts are enabled. Best practice is to ensure that compression and encryption are
also enabled. Define a transfer method.
Note: The recommended method of transfer is EMC Secure Remote Support (ESRS).
Check out the Top Reasons To Get Connected Using ESRS. Its free!
To ensure that the system reports mechanism was successfully configured:
1. Run the test_syr_connectivity command, and include a recipient_email.
2. Wait ten minutes.
3. Run get_events_log and look for event 1020 “Failed to send system report ”.
• If this event does not appear in your event logs, the system notifications
mechanism has been properly configured.
• If event 1020 is not logged; check whether there is an issue with your selected
method of transfer. If a problem exists, fix it, and run test_syr_connectivity again. Ifthe problem persists, contact EMC Customer Support.
Registering your datastores
Before protecting your VMs, you must register the datastores to be used for each copy
journal in your system. To register a datastore at a vRPA cluster:
1. In the vSphere Web Client home page, click the RecoverPoint for VMs Management
icon > Administration tab > Datastore Pools tab.
2. Select the vRPA cluster to which you wish to add datastores. Click Add.
3. In the Register Datastore Pools dialog box, select the vCenter server where the
datastores are located.
The candidate datastore pools are listed with their total size and available size.
4. Select the datastores you wish to register and click OK.
Protecting VMs
Before protecting VMs:
◆ Ensure you have added an appropriate RecoverPoint for VMs license.

RecoverPoint for VMs protection
◆ Register at least one datastore for the copy and production journals.
Limitations
◆ Maximum number of VMs in a consistency group = 16.
◆ Two VMs in one consistency group cannot have the same name, even if one is in the
production cluster and the other is a replica.
◆ When RecoverPoint for VMs automatically creates a VM at the target, the following
limitations apply:
• All VMDKs will be mapped to a single datastore. You can select the datastore, but
you cannot select different datastores for different VMDKs.
• You cannot use the Protection wizard to select different networks for each NIC in
the replica VM. VM network connections can be changed afterwards in the vSphere
GUI.
• If changes are made to the memory or CPU resources of a protected (production)
VM, those changes will not be replicated to the copy VM. The same changes can bemade manually at the copy VM.
To protect a virtual machine:
1. In the vSphere Web Client, right-click on the virtual machine you wish to protect in the
inventory. Select All RecoverPoint Actions > Protect.
2. In theSelect VM protection method
screen, choose whether to create a new
consistency group for this VM or to add this VM to an existing consistency group.
Adding a VM to an existing consistency group results in journal loss for that group.
Best practice is to protect each VM in its own consistency group.
If you choose to add this VM to an existing consistency group, continue with step 4.
3. In the Define consistency group screen:
a. Enter a descriptive name for the consistency group.
b. Select a vRPA cluster. Continue with step 5.
4. In the Select consistency group screen, select the consistency group to which the
virtual machine will be added.
5. In the Define protection policy screen:
a. Choose to automatically create a VM at the target, or select a VM to be the copy.
b. If this is a new consistency group, define the replication policy. Select synchronous
or asynchronous replication. If you select asynchronous, specify the RPO.
When allowing RecoverPoint for VMs to automatically create the target VM, continue
with step 7.
6. In the Select target VM screen, select the ESXi cluster where the target VM is located.
Select the target VM. Continue with step 10.
7. In the Select resource for target VM screen, select the resource from which to create
the target VM. You can create the target VM on an ESXi host, on an ESXi cluster, or from
a resource pool.
8. In the Select storage screen, select the datastore for the target VM.

9. In theConfigure journal provisioning
screen, define the minimum journal size for the
consistency group and select the datastore to use as the journal:
a. Select a copy from the table of copies.
b. Define the minimum journal size for that copy.
All datastores at that copy with at least as much available space as you defined islisted in the list of datastores.
c. Choose to automatically select the optimal datastore for the journal from the list or
to manually select a datastore from the list.
d. If you want to register additional datastores, click the Add button and select the
datastores you wish you register from the candidate datastores table.
You cannot proceed to the next step until all copy icons in the copy list show a green
check mark to indicate that a journal has been provisioned for each copy.
10. In the Summary screen, review previously selected values. To complete the wizard and
start replication from the production to the copy, click Finish.
The Manage > RecoverPoint for VM screen appears and displays a graphical
representation of the consistency group. The consistency group begins an
initialization process and its progress is displayed. After initialization, the consistency
group becomes active.
Stopping protection
To stop replicating the production VM:
1. In the vSphere Web Client home page, click the RecoverPoint for VMs Management
icon > Protection tab. Click Virtual Machines.
2. Select the VM you wish to stop replicating. Click the Unprotect icon:
Replication stops and the VM is removed from its consistency group. The copy VM is
not automatically deleted. If there are no other VMs in the consistency group, the
consistency group is removed.If other VMs remain in the consistency group, the
journal will be lost.

Compression Only relevant for asynchronous remote replication.
Default = None To compress data before transferring it to a remote vRPA cluster,select a level of compression. Compression can reduce transfertime significantly, but increases the source vRPA’s CPU utilization.
Enabling and disabling compression causes a short pause intransfer and a short initialization.
Enable Deduplication Only relevant for asynchronous remote replication.
Default = disabled Select this to eliminate repetitive data before transferring the datato a remote vRPA cluster. Deduplication can reduce transfer timesignificantly, but increases the source vRPA’s CPU utilization.
Enabling and disabling deduplication causes a short pause intransfer and a short initialization.
Snapshot Granularity Default = fixed per second
• Fixed per write: Creates a snapshot for every write operation.
• Fixed per second: Creates one snapshot per second. Use this forlocal replication.
• Dynamic: The system determines the snapshot granularityaccording to available resources. Use this for remote replication.

Option Description
Journal Compression Default = none
Compresses snapshots in the journal so that more images can besaved in the same journal capacity. Best practice is to compressthe journal when forcing synchronous replication.
Compression impacts the CPU resources of the target vRPA of theconsistency group.
Enabling journal compression while a consistency group is enabledwill result in the loss of all snapshots in the journal.
Maximum Journal Lag Default = unlimited
Defines the maximum amount of snapshot data (in bytes, KB, MB,or GB) that can be held in the copy journal before distribution tothe copy. In terms of RTO, this is the maximum amount of data thatwould be required in order to bring the copy up-to-date withproduction.
Required ProtectionWindow
The protection window indicates how far in time the copy imagecan be rolled back.
Select this to define a required protection window and specify thelength of the required window. You will be notified if the currentwindow is less than the required window.

Testing and Recovery
Testing and Recovery
The following testing and recovery actions are available in RecoverPoint for VMs:
◆ “Testing a copy” on page 20
◆ “Failing over” on page 22
◆ “Recovering production” on page 23
These recovery actions are directed by the Recovery Wizard and can be performed on
consistency groups or group sets. The initial steps of the wizard, including selecting the
image to access and testing the network, are the same for all recovery actions. The actual
recovery action is performed at the end of the wizard, after testing the copy.
Performing recovery activities on a group set
Before performing recovery activities on a group set, note that during image access on a
group set:
◆ When you select the latest image, the latest available image of each relevant group
copy will be accessed.
◆ When you select an image from the image list, the images of the first group in the
group set are displayed. When you select an image from the list, RecoverPoint for VMs
constructs a search query containing the parameters of the first group’s image and
queries the rest of the groups in the group set according to those parameters.
◆ When you select a specific point in time by entering advanced search options, the
same image search query is sent for all groups in the group set.
Testing a copy
To enter image access mode and test a copy:
1. In the vSphere Web Client home page, click the RecoverPoint for VMs Management
icon > Protection tab. Click the Test Copy icon:

Troubleshooting
Troubleshooting
This section describes troubleshooting issues and procedures for solving them in
RecoverPoint for VMs.
Detecting bottlenecksBottleneck detection returns statistics about RecoverPoint for VMs system performance,
by consistency group, vRPA, and vRPA cluster. Bottleneck detection analyzes the system
data in an effort to detect the existence of any of the predefined problem types, called
“bottlenecks”. The types of bottlenecks are presented in Table 12.
Table 12 Bottleneck detection
Type Output/Notes
For RPAs and Clusters
RPA balance “RPAs are not balanced.”, with data on the load handled by each vRPA at thecluster.
Note: vRPA balance is checked only if the time period defined is greater than
30 minutes.
Compression “Compression level is too high. The RPA resources cannot handle the currentlevel.”
SAN target “RPA may be regulating the application. Consider reducing RPA load.”, withdata on the total amount of incoming data, the number of writes, and theamount of incoming data per write.
RPA utilization “RPA utilization reached 80% .”
For Consistency Groups and Links
Slow productionjournal
“Writing to the local journal volume was slow during this period.”, with dataon the delay factor.
Journal phase 1 “ Journal is unable to handle the incoming data rate .”, with the required I/Orates for the journal and the replication volumes at local or remote copies, forboth normal and fast-forward distribution modes.
Journal phase 2 “ Journal and replication volumes are unable to handle the incoming datarate .”, with data on the required I/O rates for the journal and the replicationvolumes at local or remote copies, for both normal and fast-forwarddistribution modes.
Journal regulation “Remote storage is too slow to handle incoming data rate and regulate the
distribution process .” with data on the required I/O rates for the journal andthe replication volumes at local or remote copies, for both normal andfast-forward distribution modes.
Unknowndistributionproblem
“Target cluster cannot handle the incoming data rate .”, with the required I/Orates for the journal and the replication volumes at the remote cluster, forboth normal and fast-forward distribution modes.

Troubleshooting
EMC RecoverPoint for Virtual Machines Administrator’s Guide 27
To detect bottlenecks:
1. Use an SSH client to connect to the vRPA management IP address, and enter yourRecoverPoint username and password to log into the CLI.
2. Run the detect_bottlenecks command to check for any bottlenecks. To view command
parameters that can refine your search, run:
detect_bottlenecks ?
The output from the system analysis will be written to
/home/kos/statistics/bottlenecks.csv .
Load balancing
Load balancing is the process of assigning preferred vRPAs to consistency groups so thatthe preferred vRPA will perform data transfer for that group. This is done to balance load
across the system and to prevent the system from entering a high-load state.
You should perform load balancing:
◆ When a new consistency group is added to the system. Wait one week after the new
group is added to the system for a long enough traffic history to accumulate before
you perform load balancing.
◆ When a new vRPA is added to a cluster. Perform load balancing immediately after the
vRPA is added.
◆
If the system enters high load frequently. When load balancing is required, the eventlogs will display a message indicating so. When you see this message, perform load
balancing.
◆ If the bottleneck detection tool recommends it. When load balancing is required, the
detect_bottlenecks CLI command returns “RPAs are not balanced.” When you see this
message, perform load balancing.
◆ Periodically. To ensure that your system is always handling distributing loads evenly, a
script can be created to periodically perform load balancing.
To balance the load on the vRPAs:
Slow WAN “WAN is too slow .”, with data on total throughput for the cluster, the identityof the RPAs at which the problem appeared, and the throughput of that RPA(or RPAs).
Note:
A slow WAN bottleneck is detected by group, but generates data by
cluster and vRPA.
Slow read source “Reading rate from the source replication volume(s) during synchronization istoo slow .”, with the reading rate.
Slow read target “Reading rate from the target replication volume(s) during synchronization istoo slow .”, with the reading rate.
Link utilization “Link utilization reached 80% .”
