Configuring distributed segment processing

Installing and configuring DDBoost

•    Installing DDBoost

•    Configuring the Data Domain system

Installing DDBoost


NOTE: Complete descriptions of commands used in this guide are provided in the EMC Data Domain Operating System Command Reference Guide.


The overall steps for installing DDBoost are as follows:

1    Obtain the license required to enable DDBoost on the Data Domain system; purchase a DDBoost license key from EMC.

▪    The DDBoost license allows you to back up and restore data.

▪    A separate replication license enables you to perform replication. You must obtain a replication license for both the source and destination Data Domain systems.

2    Enable and configure DDBoost on the Data Domain system.

At a minimum, configuration includes specifying the DDBoost user name and password.

3    Install vRanger, which contains the DDBoost Libraries.


NOTE: This documentation illustrates the DDBoost configuration on Data Domain using commands in Data Domain OS 5.2. If you are using a different version of Data Domain operating system with this version of the DDBoost Library, see the corresponding Data Domain operating system version documentation for CLI details.

Many of the configurations done by command line can also be made using the EMC Data Domain Enterprise Manager web console.


Firewalls and ports

The EMC� Data Domain� system as it is initially configured does not work through a firewall. If you need the Data Domain system to work in the presence of a firewall, contact your network support provider.

The following ports must be open in a firewall for EMC� Data Domain� Boost (DDBoost�) backups and replication to work:

•    TCP 2049 (Network File System [NFS])

•    TCP 2051 (Replication)

•    TCP 111 (NFS portmapper)

•    TCP xxx (select a random port for NFS mountd)

Enabling DDBoost on a Data Domain system

Every EMC� Data Domain� system that is enabled for EMC� Data Domain� Boost (DDBoost�) must have a unique name. You can use the Data Domain system’s DNS name, which is always unique.


IMPORTANT: The user must be configured in vRanger to connect to the Data Domain system.


To enable DDBoost:

1    On the Data Domain system, log in as an administrative user.

2    Verify that the file system is enabled and running by entering:

      # filesys status

      The file system is enabled and running.

3    Add the DDBoost license using the license key that Data Domain provided:

      # license add license_key

      License "ABCE-BCDA-CDAB-DABC" added.

4    Set the DDBoost user by entering:

      # ddboost set user-name ddboost-user

5    Enable DDBoost by entering:

      # ddboost enable

      DD Boost enabled

Configuring the Data Domain system

This topic describes tasks and commands for configuring the EMC� Data Domain� system.

•    Creating a DDBoost user name

•    Creating Storage Units

•    Configuring distributed segment processing

•    Configuring Advanced Load Balancing and Link Failover

•    Configuring replication

Creating a DDBoost user name

An EMC� Data Domain� Boost (DDBoost�) user is an EMC� Data Domain� user. Before setting the DDBoost user access, the username and password must have already been set up on the Data Domain system. vRanger uses the DDBoost user account to connect to the DDBoost repository.

When DDBoost is enabled, a Data Domain OS administrative user can set or change to another DDBoost user. Only one DDBoost user can operate DDBoost at a time.

To set or modify the DDBoost user name:

1    In the DDBoost overview pane located under the Data Management tab, click Add or Modify in the DDBoost User area.

The Set or Modify DDBoost User Name dialog box appears.

2    Do one of the following:

▪    To add a user, click the User Name button.

a    Enter the user name in the DDBoost User Name field.

The user must be configured in the backup application to connect to the Data Domain system.

b    Enter the password twice in the text fields.

c    Select the privilege level for this user: admin or user.

▪    To switch to a user that has already been added, click the Existing User button, and select the user name from the drop-down list.

3    Click OK.

Creating Storage Units

The EMC� Data Domain� system exposes pre-made disk volumes called storage units to an EMC� Data Domain� Boost (DDBoost�)-enabled backup server. Each Storage Unit is a top-level subdirectory of the /data/col1 directory; there is no hierarchy among Storage Units. When used with vRanger, a DDBoost repository is configured at the Storage Unit level, meaning each DDBoost repository in vRanger equates to exactly one Storage Unit.


NOTE: You may also create a Storage Unit from the vRanger UI during the DDBoost repository configuration, or by using the EMC Data Domain Enterprise Manager web console.


1    To create a storage unit on the Data Domain system, enter:

      # ddboost storage-unit create storage-unit_name


IMPORTANT: Each storage unit name must be unique. For devices running Data Domain OS 5.2 and later, the supported characters are alphanumeric characters and ~!@#$^_+`-={}[],.


2    Repeat the previous step for each DDBoost-enabled Data Domain system.

Configuring distributed segment processing

The distributed segment processing option is configured on the EMC� Data Domain� system and applies to all the backup servers and the EMC� Data Domain� Boost (DDBoost�) Libraries installed on them. For more information, see Distributed segment processing.

The option can be configured using the following command:

# ddboost option set distributed-segment-processing {enabled | disabled}


NOTE: Enabling or disabling the distributed segment processing option does not require a restart of the Data Domain file system.


Distributed segment processing is supported with DDBoost Library version 2.2 or later communicating with a Data Domain system that is running Data Domain OS 5.2 or later.

Distributed segment processing is enabled by default on a system initially installed with Data Domain OS 5.2. If a system is upgraded from Data Domain OS 5.0.x to Data Domain OS 5.2 or later, distributed segment processing is left in its previous state.

Configuring Advanced Load Balancing and Link Failover

If an interface group is configured, when the EMC� Data Domain� system receives data from the backup server clients, the data transfer is load balanced and distributed as separate jobs on the private network, providing higher input and output throughput, especially for customers who use multiple 1 GbE connections.

Create an interface group on the Data Domain system by adding existing interfaces to the group and registering the Data Domain system with vRanger, as described in the following steps.

1    Verify that the interfaces have been created with the net command.

2    Add the interfaces into the group.

      # ddboost ifgroup add interface 192.168.1.1

      # ddboost ifgroup add interface 192.168.1.2

      # ddboost ifgroup add interface 192.168.1.3

      # ddboost ifgroup add interface 192.168.1.4


NOTE: Only one interface group can be created and this group cannot be named.


3    Select one interface on the Data Domain system to register with vRanger.

Quest recommends that you create a failover-aggregated interface and register that interface with vRanger.

It is not mandatory to have one of the interfaces in the ifgroup registered with vRanger. An interface that is not part of the ifgroup can also be used to register with vRanger.


NOTE: EMC recommends that you register the interface with a resolvable name using DNS or any other name resolution mechanism.


The interface registered with vRanger is used by vRanger and the DDBoost Library to communicate with the Data Domain system. If this interface is not available, backups to that Data Domain system are not possible.

4    Enable the feature on the Data Domain system:

      # ddboost ifgroup enable

5    Verify the configuration of the Data Domain system:

      # ddboost ifgroup show config

      Interface

      -------------

      192.168.1.1

      192.168.1.2

      192.168.1.3

      192.168.1.4

      -------------

After the interface group is set up, you can add or delete interfaces from the group. You can manage Advanced Load Balancing and Link Failover — an interface group — by using the ddboost ifgroup command or from the Enterprise Manager Data Management > DD Boost view. For more information, see the EMC Data Domain Operating System Administration Guide.

Configuring replication

With EMC� Data Domain� Boost (DDBoost�), vRanger can control replication between multiple EMC� Data Domain� systems and provide backup administrators with a single point of management for tracking all backups and duplicate copies. This configuration lets you efficiently create disaster recovery (DR) copies of your backups over the WAN, and track all the copies using the vRanger catalog for easy recovery.

Enabling replication

When using EMC� Data Domain� Boost (DDBoost�) with vRanger, replication is configured through the vRanger interface. For instructions on enabling replication, see Configuring repository replication.

Enabling low-bandwidth optimization

To enable the low-bandwidth option, enter:

# ddboost file-replication option set low-bw-optim enabled

Low bandwidth optimization enabled for replication.

Enabling or disabling the low-bandwidth optimization option does not require a restart of the EMC� Data Domain� file system. After enabling low-bandwidth optimization, however, you need to run a full cleaning cycle on the Data Domain system for it to be effective.

Low-bandwidth optimization can be monitored and managed with the command ddboost file replication or from the Enterprise Manager Data Management > DD Boost view. For more information, see the EMC Data Domain Operating System Administration Guide.

No configuration changes are necessary on the backup server as this feature is transparent to the data protection applications.

Notes:

•    Enabling this feature takes additional resources — CPU and memory — on the Data Domain system; Quest recommends that you use this option only when replication is being done over low-bandwidth networks with less than 6 Mbps aggregate bandwidth.

•    For more information on this feature, see the EMC Data Domain Operating System Administration Guide.

•    The low-bandwidth option for replication is supported only for standalone Data Domain systems.

Enabling encrypted file replication

To enable the encrypted file-replication option, enter:

# ddboost file-replication option set encryption enabled

The output indicates that the encryption you requested was enabled.

For more information, see the command ddboost file-replication.

No configuration changes are necessary on the backup server as this feature is transparent to the data protection application. Turning on this feature takes additional resources — CPU and memory — on an EMC� Data Domain� system.

Notes:

•    Enabling or disabling the encrypted file replication option does not require a restart of the Data Domain file system.

•    For more information on this feature, see the EMC Data Domain Operating System Administration Guide.

c.The Windows Storage Server edition is not supported as an installation platform for vRanger.

d. Before installing vRanger on Windows Server 2012 R2, the updates listed in Additional required software must be installed.


Additional required software

In addition to a supported version of Windows and a supported VMware Infrastructure, you may need some additional software components, depending on your configuration.

•    Microsoft .NET Framework: vRanger requires the .NET Framework 4.5. The vRanger installer installs it if not detected.

•    SQL Server: [Optional] vRanger utilizes two SQL Server databases for application functionality. vRanger can install a local version of SQL Express 2014 SP3 or you can choose to install the vRanger databases on your own SQL instance.

•    Windows PowerShell 3 or above.If you are installing vRanger on Windows 2008 R2 SP1, you will need to install Windows PowerShell 3 or above before installing vRanger

•    vRanger virtual appliance (VA): The vRanger VA is a small, pre-packaged Linux distribution that serves as a platform for vRanger operations away from the vRanger server. vRanger uses the VA for the following functions:

▪    Replication to and from VMware ESXi hosts.

▪    File-level restore (FLR) from Linux machines.

▪    Optionally for backups and restores.

•    Updates for Windows Server 2012 R2: Before installing vRanger on Windows Server 2012 R2, ensure that the Windows updates listed below are installed:

▪       KB2939087

▪    KB2975061

▪    KB2919355

▪    KB2999226

Installing vRanger

The installation of vRanger has several options. Unless you have a valid reason not to, Quest recommends that you accept the defaults wherever possible. The installation follows this sequence:

1    Launch the installer, and accept the vRanger license.

The install process does not continue until the license is accepted.

2    Choose an installation directory.

3    Enter the credentials under which the vRanger services should run.

Use credentials that have local administrator privileges on the vRanger machine.

4    Select the vRanger database.

You may choose to install vRanger with a new instance of SQL Server Express or on an existing SQL Server. You also need to configure DB credentials now.

The installation completes.

For more information, see the Quest vRanger Installation/Upgrade Guide.

Configuring vRanger

vRanger requires some basic configuration before data protection can begin. The bulk of this configuration is driven by the Startup Wizard which starts the first time the application is opened. For more information, see the Quest vRanger Installation/Upgrade Guide.

The following topics describe the primary configurations you need to make.

•    Adding vCenters or hosts: Before you can begin backups, you must add one or more VMware vCenter or ESXi servers to the vRanger inventory. To add a vCenter, you must have credentials with Administrator access to the vCenter, along with root-level credentials for each host managed by the vCenter. vRanger provides the option to exclude hosts from the vRanger inventory, which also excludes them from licensing.

•    Adding repositories: Repositories are where vRanger stores the savepoints created by each backup job. For the purposes of this integration, an EMC� Data Domain� Boost (DDBoost�) repository should be used.

The DDBoost server must be fully configured and running before adding it as a vRanger Repository. For procedures on how to add a DDBoost server as a repository, see Managing repository replication.

Adding an EMC Data Domain Boost (DD Boost) repository

The following process describes how to add an EMC Data Domain Boost (DD Boost) repository. The following procedure assumes that:

•    You have a properly configured Data Domain appliance that is accessible to the vRanger machine.

•    DD Boost is licensed and enabled on the Data Domain device.

•    You have designated a DD Boost User account.


NOTE: For information on setting up the preceding configurations, see your EMC Data Domain documentation.


To add an EMC Data Domain Boost Repository:

1    In the My Repositories pane, right-click anywhere, and click Add > EMC Data Domain Boost (DDB).

2    In the Add EMC Data Domain Boost Repository dialog box, complete the following fields:

▪    Repository Name: Enter a descriptive name for the repository.

▪    Description: [Optional] Enter a long-form description for the repository.

▪    DNS Name or IP: Enter the IP or FQDN for the Data Domain device.

▪    User name and Password: Enter the credentials for the account selected as the DD Boost User on the Data Domain device.


NOTE: For information on creating a DD Boost user name, see your Data Domain documentation.


▪    Storage Unit: This field specifies the Storage Unit configured on the Data Domain device. Select one from the drop-down menu, or enter the name for a new Storage Unit and vRanger creates one for you.


IMPORTANT: The supported characters are alphanumeric characters and ~!@#$^_+`-={}[],.


3    Click OK.

The connection to the repository is tested and the repository is added to the My Repositories pane and the Repository Information dialog box.

vRanger checks the configured repository location for existing manifest data to identify existing savepoints.

4    If vRanger finds existing savepoints, click the applicable button:

▪    Import as Read-Only: To import all savepoint data into the vRanger database, but only for restores, click this button. You cannot back up data to this repository.

▪    Import: To import all savepoint data into the vRanger database, click this button. vRanger is able to use the repository for backups and restores. vRanger requires read and write access to the directory.

▪    Overwrite: To retain the savepoint data on the disk and not import it into vRanger, click this button. vRanger ignores the existence of the existing savepoint data and treats the repository as new.

Configuring repository replication

Replication is configured through the My Repositories pane of the vRanger interface. The following procedure assumes that:

•    You have configured at least one DD Boost repository in vRanger.

•    At least one other Data Domain device with DD Boost enabled is available in your environment to serve as the replication target. You do not have to add this device to vRanger.

•    All devices used in replication have a Replicator license installed.

To configure replication:

1    In the My Repositories pane, right-click the Data Domain Boost repository, and select Configure Replication.

2    In the Configure Replication dialog box, complete the following fields:

▪    Repository Name: Enter a descriptive name for the repository.

▪    Description: [Optional] Enter a long-form description for the repository.

▪    DNS Name or IP: Enter the IP or FQDN for the Data Domain device.

▪    DD Boost User name and Password: Enter the credentials for the account selected as the DD Boost User on the Data Domain device.

▪    Storage Unit: This field specifies the Storage Unit configured on the Data Domain device. Select one from the drop-down menu, or enter the name for a new Storage Unit and vRanger creates one for you.

3    Click OK.

The connection to the device is tested and the device is added as a repository is added to the My Repositories pane and the Repository Information dialog box.

After replication is configured for a repository, the Configure Replication option is disabled for that repository.


IMPORTANT: After a repository is configured for replication, you must select a synchronization method before replication occurs. For information on manual and automatic synchronization options, see Managing repository replication.


Editing a replication configuration

You may edit an existing replication configuration to update credentials or timeout values. You may also use the Edit Repository Details dialog box to view free space for the repository.

1    In the My Repositories pane, right-click the EMC Data Domain Boost repository, and select Edit Replication Configuration.

2    In the Edit EMC Data Domain Boost Repository dialog box, edit any of the following fields:

▪    Repository Name

▪    User Name

▪    Password

3    Alternatively, view the Free Space field for up-to-date information about this repository.

4    If you edited any of the fields, click Update.


NOTE: For information on disabling repository replication, see Disabling repository replication.


Removing an EMC DD Boost repository

The process for removing an EMC Data Domain Boost (DD Boost) repository is the same as removing any other repository type, except that you also have the option of removing the storage unit used by the repository. There is a hard limit on the number storage units that can be configured on a Data Domain device, which makes removing unused storage units an important maintenance effort.

To remove a DD Boost repository:

1    In the My Repositories pane, right-click the applicable EMC Data Domain Boost repository, and select Remove.

The Remove Repository dialog box appears, showing the savepoints in the selected repository.

When removing a repository, you have the option of keeping the savepoints on disk or deleting them. To remove the storage unit associated with the repository, you need to remove the savepoints. If replication is configured for this repository, you are also given the option to delete the savepoints in the replicated repository.

2    Select Delete all savepoints in this repository.


CAUTION: This step deletes the savepoints from the repository disk, not just the vRanger database. Exercise caution when deleting savepoints.


3    To delete the savepoints in a replicated repository, select Delete all savepoints in replication repository.

4    Click OK.

5    When the Delete Savepoints dialog box appears, select Delete DD Boost storage unit, and click OK.

The savepoints are deleted, along with the storage unit associated with the repository.

Managing repository replication

vRanger supports repository replication. Repositories configured for replication can be synchronized in one of three ways:

•    Automatically, after a successful backup task to that repository.

•    As a separate job on a scheduled basis.

•    Manually, using the Synchronize option.

Configuring a repository for automatic replication

When a managed repository is configured for savepoint replication, and a backup task completes successfully, each savepoint is also replicated to the replication repository.

To enable automatic savepoint replication:

1    From the Tools menu on the vRanger toolbar, select Options.

2    Under the Repositories node, select Replication.


TIP: You may also right-click the target repository in the My Repositories pane, and select Repository Replication Options.


3    Select Enable savepoint replication for a successful backup job task, and click Ok.

Scheduling repository synchronization

When using scheduled repository synchronization, savepoints are replicated to the replication repository according to a configured schedule.


NOTE: When scheduling repository synchronization, ensure that the synchronization activity does not occur at the same time as backup jobs using the synchronized repository.


To schedule a repository synchronization:

1    From the Tools menu on the vRanger toolbar, select Options.

2    Under the Repositories node, select Replication.

3    In the Repository Replication Configuration pane, find the Repository Name column, and select the applicable repository.

The repositories listed are the target repositories.

4    Select Schedule repository synchronization.

5    Configure the replication schedule as desired, using the following information as a guide.

a    Start: In the drop-down list, select the time for the replication task to begin.

b    Recurrence Pattern: Establish how often the changes should be synchronized. There are five options within this section:

▫    Daily: The daily option can be scheduled to synchronize the repository every weekday or every x number of days.

▫    Weekly: Repository synchronization can be configured to run on weekly intervals, from every week to every 99 weeks. The day of the week on which to run synchronization tasks can be configured.

▫    Monthly: The monthly option offers the following configurations:

-    Day [x] of every [y] month:

x can be any value from 1 to 31. This value determines the day of the month on which the synchronization job occurs.

y can be any value from 1 to 99. This value determines the monthly interval — for example, every two months sets the job to run every other month.

-    The [f] [d] of every [y] month(s):

f can be either: first, second, third, fourth or last.

d can be: weekday, weekend day, Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, or Saturday.

y can be any value from 1 to 99. This value determines the monthly interval — for example, every two months sets the synchronization task to run every other month.

▫    Yearly: The yearly option offers the following configurations:

-    Every [m] [x]:

m is any month of the year. This value determines the month of the year in which the synchronization occurs.

x can be any value from 1 to 31. This value determines the day of the month on which the synchronization occurs.

-    The [f] [d] of [m]:

f can be either: first, second, third, fourth, or last.

d can be: day, weekday, weekend day, Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, or Saturday.

m is any month of the year. This value determines the month of the year in which the synchronization occurs.

▫    Interval: The interval option lets you select the number of days, hours, and minutes that should pass between synchronization jobs. The interval selected must be greater than or equal to five minutes.

6    Click OK to schedule the job.

Synchronizing a repository manually

1    In the My Repositories pane, right-click the source or replication repository, and select Synchronize.

2    When the confirmation prompt appears, click Yes.

Disabling repository replication

To disable repository replication:

1    Do one of the following:

▪    From the Tools menu on the vRanger toolbar, select Options. Under the Repositories node, select Replication.

▪    Right-click the replication repository, and select Repository Replication Options.

2    Clear the check box for Enable savepoint replication for a successful backup job task or Schedule repository synchronization, or both.

3    Click OK.

Replication is disabled as indicated by a red circle icon containing a white exclamation point.

Changing a replication repository to a primary repository

If your primary repository becomes corrupt or otherwise unavailable, you can quickly change your replication repository to a primary repository to continue backup and recovery operations.

To change a replication repository to a primary repository:

1    In the My Repositories pane, right-click the replication repository, and click Remove.


IMPORTANT: Ensure that Delete all savepoints in this repository is not selected.


2    Click OK.

3    In the My Repositories pane, click Add.

4    Select the applicable repository type.

5    Complete the Add Repository dialog box, and click OK.

6    When vRanger detects that the repository being added contains savepoint data and displays the Warning: Existing Repository Found dialog box, click Import to reconfigure the repository as a primary repository.
