Veeam establishes a connection with the EMC Data Domain appliance. The Gateway server is used by Veeam to communicate with EMC Data Domain since the Veeam Data Mover Service cannot be installed into EMC Data Domain storage. Make sure the Data Domain appliance name can be resolved. You must use the account created during the DD Boost configuration step in the EMC Data Domain appliance. Select Dell EMC Data Domain and click Next.Įnter the Data Domain server name and specify the credentials to access the appliance. Select Deduplicating storage appliance option and click Next. Specify a Name and optionally a Description then click Next. Click Add Repository button to configure a new repository. If EMC Data Domain is used as main backup repository instead, Veeam recommends the use of Restore entire VM and Restore VM files options for faster recovery capabilities.Ĭonfigure EMC Data Domain as Veeam backup repositoryĪccess the Backup Infrastructure area and select the Backup Repositories section. Leveraging on DD Boost protocol, backup jobs result faster since the deduplication process occurs at source-level side optimizing bandwidth usage.ĭue to the nature of EMC Data Domain storage (high compression and deduplication ratios), read and random I/O operations may result slow since each block must be recomposed and decompressed. For this reason EMC Data Domain storage should be used in the backup infrastructure as secondary backup repository for long term retention purposes. The maximum number of parallel tasks that can be targeted at the backup repository (the Limit maximum concurrent tasks to N setting) is applied to the storage unit, not the whole Dell Data Domain system.You can configure EMC Data Domain as Veeam backup repository to increase backup speed up to 50% taking advantage of EMC's DD Boost protocol. Veeam Backup & Replication supports per storage unit streams on Dell Data Domain. Veeam Backup & Replication will leverage the Dell Data Domain technology to encrypt data transported between the DD Boost library and Data Domain system. If necessary, you can enable data encryption at the backup repository level. Veeam Backup & Replication supports in-flight encryption introduced in Dell Data Domain Boost 3.0. Virtual Synthetic Fulls reduce the workload on the network and backup infrastructure components and increase the backup job performance.

To construct a full backup file, Dell Data Domain uses pointers to existing data segments on the target backup storage. Virtual Synthetic Fulls let you synthesize a full backup on the target backup storage without physically copying data from source volumes. Veeam Backup & Replication supports Virtual Synthetic Fulls by Dell Data Domain. If some link in the group goes down, Dell Data Domain automatically performs link failover, and the backup traffic is routed to a working link. As a result, Dell Data Domain automatically balances the traffic load coming from several gateway servers united in one group. If a network error occurs during the data transfer process, the backup job fails and needs to be restarted.Īdvanced Load Balancing allows you to aggregate several Ethernet links into one interface group. Such configuration does not provide an ability to balance the data transfer load across the links. Without Advanced Load Balancing, every gateway server connects to Data Domain on a dedicated Ethernet link. As a result, the load on the network reduces and the network throughput improves.Īdvanced Load Balancing and Link FailoverĪdvanced Load Balancing and Link Failover allow you to balance data transfer load and route VM data traffic to a working link in case of network outage problems. The gateway server sends only unique data blocks to Dell Data Domain. With Distributed Segment Processing, operations on data segmentation, filtering and compression are performed on the gateway server side. Data segmentation, filtering and compression operations are performed on the target side, before data is written to disk. The gateway server sends unfiltered data blocks to Dell Data Domain over the network. Without Distributed Segment Processing, Dell Data Domain performs deduplication on the Dell Data Domain storage system. However, you can import and map backups replicated between Data Domain storage systems to backup, backup copy or replication jobs, or perform restore operations from such backups.ĭistributed Segment Processing lets Dell Data Domain "distribute" the deduplication process and perform a part of data deduplication operations on the gateway server side. You cannot configure Managed File Replication using Veeam Backup & Replication.
