Question: What is DD Boost?

Answer: DD Boost software advances Data Domain performance and simplicity differentiators over all competitors. DD Boost provides advanced integration between Data Domain systems and leading backup and enterprise applications. DD Boost distributes parts of the deduplication process to the backup server or application client to increase the aggregate throughput to a Data Domain system up to 50 percent.

Using DD Boost, the application server only sends unique data to a Data Domain system. This enables more backups with existing resources, 20 to 40 percent less overall impact to the server, and 80 to 99 percent less LAN bandwidth consumed. This functionality is transparent to the application and reduces “time-to-DR readiness.”

In addition, DD Boost simplifies backup administration by offering the ability to manage Data Domain replication through the application. Finally, DD Boost eliminates the need for Ethernet layer aggregation to leverage the full capabilities of multiple Ethernet ports.

Question: What are the major features and benefits of DD Boost?

Answer: DD Boost software provides:

• Distributed deduplication, which distributes parts of the deduplication process from the Data Domain system to the backup or application server, increasing backup application performance by up to 50 percent. In addition, this reduces LAN/SAN bandwidth by up to 99 percent.

• Managed file replication, which allows backup applications to manage Data Domain replication. For those familiar with Symantec NetBackup OpenStorage, this feature is referred to as “optimized duplication” and is referred to as “clone-controlled replication” with Dell EMC NetWorker.

• Advanced load balancing and link failover, which provides link aggregation for load balancing and link failover, which eliminates the need for Ethernet layer aggregation.

• Virtual Synthetic Backups, which support Symantec NetBackup Optimized Synthetic backups to reduce processing overhead associated with traditional synthetic full backups. Unlike traditional synthetic backups, Virtual Synthetics synthesizes a full backup from existing data on the Data Domain system without moving redundant data across the network.

Question: Can I use DD Boost to backup over the WAN to a Data Domain system?

Answer: Yes, DD Boost over WAN is supported with Dell EMC NetWorker and Dell EMC Avamar. DD Boost over WAN is also supported with Symantec NetBackup for selected network environments via RPQ.

INCLUDED ADD-ON: DATA DOMAIN ENCRYPTION

Question: What is DD Encryption software?

Answer: DD Encryption is a software option that provides inline encryption of user data at rest on deduplication storage, enabling organizations to enhance the security of their user data stored on the Data Domain system.

Question: How does DD Encryption work?

Answer: DD Encryption seamlessly integrates with the Data Domain high-speed, inline deduplication process and encrypts data before it is written to disk. Utilizing encryption—with AES-128 or AES-256 algorithms—allows user data to be protected in case of theft.

Encrypting data at rest satisfies some aspects of internal governance rules and compliance regulations and also uses RSA® BSAFE FIPS 140-2 validated cryptographic libraries

It protects a user’s data against theft of a Data Domain system or loss of the physical storage media during transit, and eliminates accidental exposure during the replacement of failed drives.

This capability works with all Data Domain protocols and applications (except Data Domain systems using DD Extended Retention). DD Encryption can also be used with DD Replicator to send encrypted data over the WAN.

Question: What is the benefit of DD Encryption?

Answer: Inline encryption provides increased security because data is encrypted before it is stored on disk. With an inline approach, data never resides in a vulnerable, unencrypted state on the disk subsystem.

The proliferation of publicized data loss, coupled with new governance and compliance regulations, is driving the need for customers to encrypt their data at rest. DD Encryption software provides a way for organizations to further protect their backup and archive data from theft

Question: How does DD Encryption software manage encryption keys?

5 |

Data Domain FAQ © 2017 Dell Inc. or its subsidiaries.

Answer: Data Domain Encryption software includes an internal key manager to configure and manage key rotation on a single Data Domain system. This internal key manager offers a cost effective alternative to using enterprise-wide key management from RSA Data Protection Manager (DPM). This helps meet compliance requirements with the ability to do local encryption key rotation without requiring investment in the RSA DPM enterprise key management solution.

In addition, through integration with RSA Data Protection Manager (DPM) delivers external key management for Data Domain systems and the entire enterprise. RSA DPM delivers a robust, enterprise-wide encryption key life cycle management solution. It increases security by rotating keys, limiting exposure if a key is compromised, and also provides key vaulting.

Question: What does the added support for KMIP servers deliver?

Answer: Key Management Interoperability Protocol, or KMIP, can now be utilized to manage data-at-rest encryption on Data Domain. The KMIP server supported in DD OS 6.1 is SafeNet KeySecure 8.4. Users will be able to use SafeNet KeySecure 8.4 to manage & rotate encryption keys securely for encrypted data. With the ability to switch between all supported Key management solutions (SafeNet KeySecure 8.4, Embedded Key Manager or RSA DPM) per the company’s security policies without affecting the data, our customers will have even more flexibility to bring the security they desire to their backup environment.

INCLUDED ADD-ON: DATA DOMAIN REPLICATOR

Question: What is DD Replicator?

Answer: Data Domain Replicator is a software option that provides network-efficient, automated, ultra-safe replication for DR, remote office data protection, and multi-site tape consolidation. Data Domain Replicator software vaults or asynchronously replicates only the compressed, deduplicated data over the wide area network (WAN), making network-based replication economically and operationally feasible.

Question: What replication types are supported for the various protocols to ingest data in the Data Domain system?

Answer: The table below outlines the differences:

Protocol Supported Replication Type CIFS, NFS, VTL, NDMP

MTree, Directory, Collection

DD Boost Managed file, Collection

Question: What are key features of DD Replicator?

Answer: DD Replicator offers:

• Safe and network-efficient replication by encrypting all or a portion of the data to be replicated. Data is deduplicated as it is being written to the Data Domain system and DD Replicator preserves this deduplication, thereby reducing the network utilization.

• Scalable replication throughput—up to 54 TB/hr for logical data enabling the fastest time-to-DR readiness. DD Replicator is an ideal DR solution for enterprise data centers that require high-throughput replication mechanisms to move data to an offsite location.

• Flexible replication topologies. The Data Domain systems can be deployed either in one-to-one, one-to-many, many-to-one, bi-directional, or cascaded modes to meet a wide variety of customer use cases.

• Compatibility with enterprise applications. Data Domain systems can be used in existing enterprise deployments.

Question: How scalable is DD Cloud Tier?

Answer: DD Cloud Tier can scale up to 2x the max capacity of the active tier, increasing the overall Data Domain system scalability by up to 3x. For example, the DD3300 scales up to 32 TB of usable capacity on the active tier, therefore the cloud tier can support up to 64 TB of usable capacity for a total usable capacity of 96 TB. This results in up to 3.2 PB of logical capacity being efficiently protected in the cloud – and a total of 4.8 PB across the local system and cloud.

Question: How does Data Domain Cloud Tier lower overall TCO?

Answer: Data Domain provides the most cost-effective long-term retention in the cloud through industry leading deduplication efficiency that enables an average of 10 – 55x reduction in storage requirements. When moving data to the cloud, DD Cloud Tier ensures that only unique data is sent and data lands on the cloud object storage already deduplicated. Protecting more data in a smaller footprint greatly reduces overall TCO and as more data is sent, cost savings will continue to increase over time. Plus, when recalling data from the cloud, only unique data is sent back to Data Domain reducing resource requirements and enabling faster data retrieval for additional time and cost savings.

Question: How do I know the data being stored in the cloud is secure?

Answer: Security of data in the cloud, particularly the public cloud, is a huge concern for many customers. DD Cloud Tier supports DD Encryption to ensure data being sent to the cloud remains secure. Customers have the option to leverage DD Encryption to encrypt all data on the Data Domain system or encrypt just the data being stored in the cloud tier. In addition, DD Retention Lock provides the ability to do individual file locking to data being sent to the cloud to meet compliance requirements.

Question: What clouds does Data Domain Cloud Tier support?

Answer: Dell EMC is expanding cloud service provider support for long-term cloud retention. Data Domain Cloud Tier currently supports native-tiering to Dell EMC Elastic Cloud Storage, Virtustream Storage Cloud, Amazon AWS and Microsoft Azure. With Data Domain Operating System 6.1, support for Federal AWS Commercial Cloud Services (C2S) & Virtustream Infrequent Access Storage was added to expand DD Cloud Tier’s cloud ecosystem. Now with DD OS 6.1.1, Dell EMC is further expanding cloud provider support to include Azure Government cloud. Data Domain Cloud Tier is also now supported with Dell EMC Elastic Cloud Storage (ECS) geo-replication. Using Data Domain Cloud Tier, customers can now tier data to the primary ECS site with geo-replication enabled to a secondary site, thus providing reliable access to cloud data in the event of site failures.

Question: Can non-certified 3rd party backup applications directly restore with DD Cloud Tier?

Answer: With Data Domain Operating System 6.1, direct restores of DD Cloud Tier are now available for non-certified 3rd party backup applications in addition to the previously certified applications.

Question: What are the new enhancements around DD Cloud Tier & disaster recovery?

Answer: Dell EMC has enhanced DD Cloud Tier for reliable disaster recovery across three critical disaster scenarios: DD Cloud Tier metadata shelves failure & recovery, Data Domain system & DD Cloud Tier metadata shelves failure & recovery, and a full site recovery that includes a geo-replicated ECS. With DD OS 6.1, these DR scenarios are enabled under a variety of replication configurations – including both MFR and Mtree replication. If a disaster occurs, Dell EMC is able to establish connection back to the cloud, install new metadata shelves on the Data Domain, and then rebuild the segment index on the new shelves to gain access to the data in the cloud. This is a support driven engagement.

Question: What scenarios are covered by the DD Cloud Tier DR enhancements?

8 |

Data Domain FAQ © 2017 Dell Inc. or its subsidiaries.

Answer: These scenarios are expected to be very rare occurrences. However, it remains important that we can provide assurance to DD Cloud Tier customers that there is resiliency built into the product.

▪ DD Cloud Tier metadata shelves failure & recovery: Once a connection back to the cloud is established, Dell EMC can install new metadata shelves on the Data Domain and then rebuild the segment index on the new shelves to gain access to the data in the cloud.

▪ Data Domain system & DD Cloud Tier metadata shelves failure & recovery: If the Data Domain system itself fails (so that both the controller & metadata drives fail), we can help customers recover their data by first recovering the Cloud Tier and then the Active Tier. A new Data Domain and new metadata shelves are required as the full solution is recovered.

▪ Full site failure & recovery that includes a geo-replicated ECS: If customers have an on-site ECS replicating to a secondary ECS at a DR site, and the entire primary site goes down, we can help customers stand up a new Data Domain with new metadata shelves and point the system to the secondary ECS site.

Thanks to these enhancements, you can assure potential customers that critical long-term retention data can be reliable recovered under any disaster scenario with Data Domain Cloud Tier.

AVAILABLE ADD-ON: DATA DOMAIN CLOUD DR

Question: What is Data Domain Cloud Disaster Recovery?

Answer: Data Domain Cloud DR (DD CDR) enables customers running Avamar and Data Domain to protect their environments from an on-prem Data Domain directly to AWS S3 (object storage). During a recovery process the solution provides a per-VM conversation into AWS AMI, while automatically provision EBS, network and EC2 volume. After the recovery process is completed, the workloads run natively in AWS.

Question: What are the main benefits of Data Domain Cloud DR?

Answer: Extension of the existing data protection from the customers’ premises to the cloud provides a familiar user experience, thus requiring minimal education and training, resulting in lower TCO and higher ROI. Using Data Domain Cloud DR, you can leverage the agility and scale of public cloud for DR, with minimal cloud footprint (no additional compute is required during routine replication, and minimal compute is required in case of test or recovery). Cloud DR version 17.3 introduces a unique capability of orchestrating not only the failover, but also the failback of workloads from AWS back to an on-prem environment.

Question: How do I know that Data Domain Cloud DR is the right solution for me?

Answer: Data Domain Cloud DR is right for you if you seek to protect data stored on Data Domain directly to AWS S3 using your existing Dell EMC protection environment. If you require a simple disaster recovery and failback process, but do not want to or cannot create a replica site on your premises. Data Domain Cloud DR can also be used for tertiary copies of your data, providing a secondary replica site.

Question: How is Data Domain Cloud DR different from Data Domain Cloud Tier?

Answer: Both Data Domain Cloud DR and Data Domain Cloud Tier are features that can be added on to the on-premises Data Domain offering, to copy data to AWS object store (S3). However, Cloud Tier replication is used for long term retention, allowing users to access older copies of their data by recovering the data on their premises. Cloud DR enables access to more recent copies, in case of a disaster, allowing orchestrated recovery of the data in AWS by rehydrating the data stored in object store (S3) to block storage (EBS), converting to Amazon compute format (EC2 instances) and bringing up a replica environment in AWS. Cloud DR also supports orchestrated failback to customer premises of recovered workloads

The CDRS performs per-VM conversion into EC2 instances, on demand.

11 |

Data Domain FAQ © 2017 Dell Inc. or its subsidiaries.

The application continues to write and changes are marked by Data Domain. The CDRA retrieves these changes and transfers them to S3.

Question: Describe data movement of failback in detail.

Answer: The user initiates failback from the CDRS.To failback to a specific on-prem vCenter environment, Cloud DR creates a restore helper VM on-prem, that has connectivity to AWS and to the on-prem datastores. At deployment (or later), the user specifies some details that allows such a restore VM to operate – including network(s) with connectivity to AWS and storage targets. Upon failback, the EBS disks are copied to S3 object storage; then the restore VM copies these objects to the customer’s premises, and constructs a restored VM. Following the restore, the customer can move the VM to a different location in his on-prem environment.

Question: How much data can I transfer to the cloud?

Answer: The solution has been qualified to support 120 TB of on prem data that can be copied to the AWS cloud.

Question: What kind of consistency does Data Domain Cloud DR support?

Question: Can a customer protect VMs to more than one AWS region with Data Domain Cloud DR?

Answer: Yes, you can configure DR to more than one region using Data Domain Cloud DR. Prerequisite to configuration of this protection is the configuration of several cloud targets, each pointing to a different AWS region. This is done as part of the deployment process, from the CDRA GUI. Note that additional cloud targets can also be configured after deployment.Protecting the same VM to different AWS regions is done from the Avamar GUI, where you can configure a VM in multiple Avamar groups and protecting each of these groups to a different cloud target. Refer to the Data Domain Cloud Disaster Recovery Installation and Administration Guide for further information.

Question: Are multiple AWS availability zones supported by Data Domain Cloud DR?

Answer: Protection is done to a specific region in S3, and the data is available to all Availability Zones (AZ) in that region. Workloads are recoverable to different AZs in a region. During test/failover the customer selects an AWS subnet they pre-created. A subnet belongs to a single AZ and is where the EC2 instances will be created for that test/failover operation. Customers that look for a specific multi-AZ topology can configure their subnets and security groups accordingly (as they would do for anything else they run in AWS).
