Executive Summary One of the characteristics of vranger is that while it s easy to use, vranger gone a step further with EMC Data Domain Deduplication storage system by integrating vranger with DD Boost software. Here we ll explore the mechanics behind the integration, then walk through the setup. Data Domain provides high speed, inline deduplication and storage of vranger backups, and can replicate the backups over the WAN to other Data Domain systems for enhanced and advanced disaster recovery purposes. For more detailed information on Data Domain, please visit EMC Data Domain site. Historically, many administrators stream vranger backups to Data Domain systems using CIFS repositories. Data Domain also provides backup application integration through DD Boost, which has been included in vranger since version 5.4. There are two components to DD Boost: The DD Boost Feature that runs on the Data Domain system, which requires a license key to operate that can be obtained from EMC, the license is named as DDBOOST The DD Boost libraries that ship with vranger, which is enabled out of the box and does not require additional licenses. Also vranger do not require any OST / plugin s to be installed in order to be integrated with DDBoost backup targets. Target Audience This white paper is intended for customers & Implementation Specialists in EMC Professional Service who is looking to understand & perform the integration of Data Domain with Dell vranger Backup Application using DDBoost. Also this document provides Step by step information about How to integrate the Data Domain (using DDBoost) with Dell vranger. For Version Compatibility with DD OS version & DDBoost version with vranger & Application OS version please refer to DDBoost Compatibility Guide from EMC Support Website Fonts used in this document Font Name - Verdana, Size - 10 : For document contents Font Name Courier, Size 9 : For Commands Font Name Verdana, Size 13, Bold : For Document Headings Font Name Verdana, Size 11, Bold : For Document Sub Headings Why Data Domain Increasing the capacity speed and cost-effectiveness of data storage is a perpetual challenge. One of the most expensive and resource intensive tasks is gathering storing and protecting data for backups. Writing data to tape and shipping and storing the tapes off-site is one of the largest financial and labour resource challenges in the conventional tape centric environment. Data Domain systems simplify the storage and handling of data by reducing, or in many cases, entirely eliminating the need for tape for data storage. With Data Domain system, data is backed up to disk instead of tape. Data Domain deduplication greatly reduces the data footprint before the data is backed up. Data Domain global compression technology combines and exceptionally efficient high-performance in-line deduplication technology with a local compression technique. The reduced data footprint allows data to be retained on-site for longer periods and allows transfer across the network for archival. Data Recovery is similarly transformed by the elimination of the time-consuming and resource intensive handling of tape. This reduces the Backup & Restore window massively, with huge performance benefit to customers. 4
What is vranger vranger is a VMware data protection backup solution that also backs up and recovers Windows physical servers. With vranger, you get comprehensive protection for both virtual and physical environments that you can manage from one intuitive interface. Legacy vranger had support Data Domain systems as repositories, but required that the Data Domain system was configured as a CIFS share. vranger extends this functionality to support the more advanced functionality offered by Data Domain Boost, and allow direct configuration of Data Domain Boost repositories. Important considerations while integrating DDboost with vranger. Well whenever it comes to a new integration there are a lot to consider, let s simplify the list in the below order. i) Version and bit structure of the Operating System on which the Backup Application is running. ii) iii) iv) Backup Application Software (Dell vranger is this case) version and features, we must ensure the application version we are using is compatible or supported. Data Domain Operating System version, and DDBoost Version. If Data Domain have Proper Licenses available, we need DDBOOST license in this case Please refer to the DDBoost Compatibility Guide for verifying all the mentioned compatibility, You can access latest DDBoost Compatibility guide by clicking here Configuring Data Domain The Configuration of data Domain is the first step form where we need to start. Please make sure the Data Domain hostname, DNS, and IP interfaces are configured properly and the lookup is working properly for both A record & PTR records in DNS. In case if you have any firewall between the Data Domain and vranger Server then the below ports need to be open. Port # Function Description Inbound Ports TCP 111 UDP 111 DDBOOST/ NFS DDBOOST/ NFS Used to assign a random port for the mountd service used by NFS and DDBOOST. mountd service port can be statically assigned. Used to assign a random port for the mountd service used by NFS and DDBOOST. mountd service port can be statically assigned. UDP 161 SNMP (Query) Port is used only if SNMP is enabled, Run 'snmp status' to determine if SNMP is running TCP 2049 DDBoost/NFS Main Port used by NFS TCP 2051 TCP 2052 Outbound Ports Replication / DDBoost NFS mountd / DDBoost Port is used only if replication is configured on the Data Domain system. Main Port used by NFS mountd UDP 162 SNMP Trap Used by data Domain system to send SNMP traps to SNMP host. TCP 2051 Replication / DDBoost Port is used only if replication is configured on the Data Domain system. Please make sure the File System is running # filesys status 5 P a g e

Data Domain is fully configured to be integrated with vranger now. Please note the below three information for integration purpose 1. DDBoost User Name (here ostuser) and correct Password 2. Fully Qualified Domain Name of the Data Domain (Host Name of the data Domain. 3. Storage Unit Name you are going to use. Adding EMC DDBoost (DDB) in vranger repository Login to vranger Server, run nslookup to verify the below lookups (DNS Query) Data Domain Host Name & IP Address is resolving from both Forward & Reverse lookup vranger Server Hostname & IP Address is resolving from both Forward & Reverse lookup Login to vranger 1. To add a DD Boost repository, navigate to the My Repositories pane. Right-click anywhere in the My Repositories pane. Select Add > EMC Data Domain Boost (DDB). 2. On the Add EMC Data Domain Boost Repository dialog, populate the fields below: a. Repository Name a descriptive name for the repository. b. Description a long form description for the repository. This is an optional field. c. DNS Name or IP the IP or FQDN for the Data Domain device. 6 P a g e
d. User name/password these are the credentials for the account selected as the DD Boost User on the Data Domain device. In this example it was ostuser 3. Storage Unit this is 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 will create one for you. The Window will all the information populated will look like below. Click OK. The Below window will complete the task. 4. vranger will check the configured repository location for existing manifest data to identify existing savepoints. If any are found, you will be prompted to take one of three actions: a. Import as Read-Only with this option, all savepoint data will be imported into the vranger database, but only for restores. You will not be able to back up to this repository. b. Import all savepoint data will be imported into the vranger database. vranger will be able to use the repository for backups and restores. vranger requires read and write access to the directory. c. Overwrite the savepoint data will be retained on the disk, but will not be imported into vranger. vranger will ignore the existence of the existing savepoint data and treat the repository as new. 7 P a g e
Configuring Repository Replication MFR Managed File Replication is configured through the My Repositories view of the vranger administration interface. The procedure below requires the following statements to be true: Already configured at least one DD Boost repository in vranger. At least Second Data Domain device with DD Boost enabled is configured in your environment to satisfy the replication target. This device does not need to be added to vranger. Both the Data Domain systems used in replication have a REPLICATOR license installed. To configure Managed File Replication 1. From the My Repositories view, right-click on the Data Domain Boost repository and select Configure Replication. 2. On the Configure Replication dialog, populate the fields below: a. Repository Name a descriptive name for the repository. b. Description a long form description for the repository. This is an optional field. c. DNS Name or IP the IP or FQDN for the Data Domain device. d. DD Boost User name/password these are the credentials for the account selected as the DD Boost User on the Data Domain device. e. Storage Unit this is 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 will create one for you. 8 P a g e
3. Click OK. The Below window will complete the task. Once Managed File Replication is configured for a repository, the Configure Replication option will be disabled for that repository. Technical terminology used and references. DDBoost: The DD Boost protocol enables backup servers to communicate with storage systems without the need for Data Domain systems to emulate tape. There are two components to DD Boost: one component that runs on the backup server and another component that runs on a Data Domain system. Storage Unit: To store backup data using DD Boost, the Data Domain system exposes user-created disk volumes called storage units (SUs) to a DD Boost-enabled application host. DDB: Data Domain Boost Repository specific to vranger Application which refers to a Device where data is stored. Equivalent to Device in EMC NetWorker. Replication: Creating another copy of data by reading from the 1 st copy of backup. The important thing to remember is while replicating, the data is being read from the source backup device not from the client. So no utilization of client is required. MFR: Manage File Replication is a feature of DDBoost which enables the backup application to be aware of the second copy of data in another device. Or can be termed as Catalog aware replication.
