Product Version: 7.5

Last Modified: 04 June 2018

Background

EMC Data Domain Boost, or DD Boost, is a protocol that enhances interaction of backup applications with Data Domain storage appliances. DD Boost offloads part of the EMC Data Domain deduplication to backup application side.

Question

Is it possible to integrate NAKIVO Backup & Replication with EMC DD Boost?

Answer

Starting from NAKIVO Backup & Replication version 7.5, you can create a Backup Repository on an EMC Data Domain appliance with DD Boost support.

To incorporate DD Boost features into NAKIVO Backup & Replication, BoostFS Plugin has to be installed on the Linux machine where NAKIVO Backup & Replication is deployed. It will allow a DD Boost storage unit to be configured as NAKIVO Backup Repository via mounting DD Boost file system on Linux.

Prerequisites

The following required prior to creating a Backup Repository on an EMC Data Domain backup appliance with DD Boost support:

  1. A physical or virtual Data Domain with DD OS Version 6.1 or later is deployed and running.
  2. A full solution of NAKIVO Backup & Replication or a NAKIVO Transporter only solution version 7.5 or later is deployed on a Linux machine, either as a VMware virtual appliance or a customized Linux installation.

Installing BoostFS Plugin on Linux Server

Please follow the steps below to install BoostFS Plugin on a Linux server where NAKIVO Backup & Replication is deployed and running:

  1. Login to the Linux machine where NAKIVO Backup & Replication is installed.
  2. Download the BoostFS Plugin package:
    wget http://downloads.emc.com/emc-com/usa/DataDomain/BFSAVT-<bfsavt-version>.tar.gz
    where <bfsavt-version> is a version of the BoostFS Plugin package. For updated information please refer to the How-to Deploy and Configure BoostFS manual on the https://community.emc.com/docs/DOC-55321 address.
  3. Unpack the contents of the package:
    tar -xzvf BFSAVT-<bfsavt-version>.tar.gz
  4. Change directory to bfsprofiler/boostfs-pkg.
  5. Check the content of the directory with the ls command to obtain the correct name of the package necessary for the next step.
  6. Install the package on the Linux machine by running the following command:
    • On Ubuntu: dpkg -i DDBoostFS_<ddboostfs_version>_amd64.deb
    • On Red Hat: rpm -Uvh DDBoostFS-<ddboostfs_version>.rhel.x86_64.rpm
    • On SUSE: rpm -Uvh DDBoostFS-<ddboostfs_version>.sles.x86_64.rpm

where <ddboostfs_version> is the correct version of the package.

Creating Storage Unit on Data Domain Backup Appliance

Please follow the steps below to create a storage unit to be used by NAKIVO Backup & Replication as a Backup Repository:

  1. Open Data Domain System Manager of your Data Domain backup appliance and go to Data Management -> File System.
  2. Make sure that file system is created. If file system is not created, click Create and follow file system creation wizard instructions.
  3. In Data Domain System Manager, go to Protocols -> DD Boost. If DD Boost is disabled, click Enable.
  4. Create a new storage unit by following the steps below:
    1. On the DD Boost page, open the Storage Units tab.
    2. In Storage Units, click Add.
    3. The Create Storage Unit dialog opens. Enter the following data:
      1. Name: add a name of your storage unit.
      2. User: choose a local user for accessing your storage unit. If needed, create a new user by choosing Create a new Local User.
      3. Click the Create button when ready to create your storage unit.

If the operation succeeds, your storage unit will appear in the list of Data Domain storage units.

Creating NAKIVO Backup Repository on EMC Data Domain Backup Appliance

Please follow the steps below to create Backup Repository on DD Boost storage unit:

  1. On the Linux server where NAKIVO Backup & Replication is deployed, create a lockbox file that the Data Domain backup appliance will use to store the Data Domain system information, including the DD Boost storage unit name and storage unit credentials:
    1. Change directory to /opt/emc/boostfs/bin/.
    2. Enter the command:
      ./boostfs lockbox set -u <user> -d <backup_appliance> -s <storage_unit>
      where <user> is the user account for accessing your storage unit, <backup_appliance> is the IP address of the Data Domain backup appliance, and <storage_unit> is the name of the DD Boost storage unit.
    3. In the prompt that opens, enter the storage unit user password and then enter the user password again to confirm it.
  2. Open NAKIVO Backup & Replication dashboard and go to Configuration -> Repositories.
  3. Click Add Backup Repository and then Create new backup repository.
  4. In the Create Backup Repository dialog that opens, enter the following data:
    1. Name: provide a name for your Backup Repository.
    2. Select the The target is a deduplication appliance checkbox.
    3. Assigned transporter: choose the transporter for which BoostFS Plugin is installed.
    4. Type: choose Incremental with full backups for your Backup Repository type.
    5. Location: choose Remote NFS share.

      Note

      Because of a NAKIVO Backup & Replication advanced mount option – see below, – DD Boost will be used instead of remote NFS share.

    6. Path to the share: enter the values you used on Step 1.b in the form <backup_appliance>:/<storage_unit>.
    7. Select the Advanced mount options checkbox and then enter ddboost in the text box that becomes available.

      Important

      If this step omitted, a remote NFS share will be used instead of DD Boost.

    8. Click Create.

If the operation succeeds, your Backup Repository on the EMC Data Domain backup appliance will appear in the list of NAKIVO Backup Repositories.
