General recommendations

4

EMC Data Domain and Veeam Bac kup & Rep lic a tion v9.5 Integra tion Guide

General recommendations In backup environments, several factors impact the effectiveness of the solution. Understanding the environment and how the user experience is affected by the factors discussed here can help you architect a successful solution. This section describes key areas and best practices that can help mitigate negative behavior:

• Data set profile

• Scheduling of operations

Data set profile The number of files is important when using Data Domain systems. Data Domain systems can only comfortably handle 100 million files. Keep this in mind when deploying a single system with both backup and archive workloads. Exceeding this limit severely impacts system performance.

Scheduling of operations When deploying a Data Domain system as a backup target in a mixed use capacity, consider the scheduling of operations such as backups and replication. These operations consume resources and impact performance.

For optimal performance:

• Ensure that backup and replication operations finish before normal business hours to avoid disrupting end-user access to the Data Domain system.

• Establish backup policies with an understanding of these background operations and when they occur.

• Cleaning can be scheduled on a daily, weekly, or monthly basis. For datasets with millions of files, cleaning may take several days and consume system resources.

Veeam Backup & Replication configuration - backup infrastructure

Set up the backup infrastructure before performing data protection and disaster recovery tasks with Veeam Backup & Replication. The backup infrastructure architecture may vary depending on your virtual environment and backup strategy.

A typical backup infrastructure consists of the following components:

• Veeam backup server — the server on which Veeam Backup & Replication is installed.

• Virtual infrastructure servers — virtualization hosts used as sources and targets for backup, replication, and other types of jobs

• Backup proxies — “data mover” component servers. By default, the backup proxy role is assigned to the Veeam backup server or source Hyper-V host. However, you can configure dedicated backup proxies. The Veeam Backup & Replication User Guide provides more information.

• Repositories — locations for storing backup files, auxiliary replica files, and VM copies.

Veeam Backup & Replication configuration - CIFS Configure Veeam Backup & Replication to use the Data Domain system as a backup target, perform a test backup, and restore a backed up file in a Windows environment.

Configure a CIFS share as a backup target You can store backups on CIFS shares created on Data Domain MTrees.

A CIFS backup repository provides a simpler setup process, but less throughput for Veeam Backup & Replication (including using the intermediate Linux system) than an NFS backup target. You can use the CIFS protocol for small environments (source virtual machine storage less than 3TB) or environments that cannot accept a Linux system.

1. Select Backup Infrastructure > Backup Repositories > Add Backup Repository.

6. In the Gateway server section, specify settings for the gateway server:

• If a network connection between the source datastore and backup repository is fast, choose Automatic selection. In this case, Veeam Backup & Replication will automatically select a gateway server.

• If you perform backup and replication over WAN or slow connections, choose The following server. From the list below, select a Microsoft Windows server on the target site that you want to use as a gateway server. The selected server must have a direct access to the shared folder and must be located as close to the shared folder as possible.

In some cases, the automatic selection mechanism may cause problems as Veeam Backup & Replication may use different gateway servers for different job sessions. For example, during one job session Veeam Backup & Replication may use a 64-bit gateway server to create a backup file. If during the next job session Veeam Backup & Replication uses a 32-bit gateway server, Veeam Backup & Replication will fail to open the created backup file in the backup repository. To overcome this situation, you must explicitly define the gateway server.

8. At the Mount Server step of the wizard, specify settings for the mount server that you plan to use for file-level and application items restore. From the Mount Server list, select a server that you want to use as a mount server. The mount server is required for file-level and application items restore. During the restore process, Veeam Backup & Replication will mount the VM disks from the backup file residing in the backup repository to the mount server. As a result, VM data will not have travel over the network, which will reduce the load on the network and speed up the restore process.

9. To make the backup repository accessible by the Veeam vPower NFS Service, select the Enable vPower NFS server on the mount server check box. Veeam Backup & Replication will enable the vPower NFS Service on the mount server you have selected.

10. In the Folder field, specify a folder that will be used as a vPower NFS root folder.

EMC Data Domain and Veeam Bac kup & Rep lic a tion v9.5 Integra tion Guide

Perform a test backup In Veeam Backup & Replication, backup is a job-driven process. To back up VMs, you must configure a backup job. The backup job defines how, where, and when to back up VM data. One job can be used to process one or more VMs.

Veeam Backup & Replication backs up a VM image as a whole, copying VM data at a block level, retrieves VM data from the source storage and writes the data to the backup repository in Veeam’s proprietary format. Image-level backups work for all types of data restore scenarios: restore a full VM, VM guest OS files and folders, and VM files and VM virtual disks (for VMware VMs only) from the backup file.

Veeam Backup & Replication performs both full and incremental backups. During the first run of a backup job, Veeam Backup & Replication creates a full VM backup (VBK). All subsequent job cycles produce incremental backups:

• VIB if forever forward incremental or forward incremental backup is used

• VRB if reversed incremental backup is used.

The number of incremental backups kept on disk depends on retention policy settings.

This section describes the basic steps to create a backup job. The “Creating Backup Jobs” section of the Veeam Backup & Replication User Guide provides more detailed information.

5. At the Storage step, select the new backup repository from the Backup repository list. Veeam Backup & Replication will use this backup repository as a backup target.

6. In the Retention policy section, specify how many restore points to keep in the backup repository.

Note that the length of forward incremental and forever forward incremental backup chains (chains that contain one full backup and a set of subsequent incremental backups) cannot be greater than 60 restore points. To overcome this limitation, schedule full backups (active or synthetic) to split the backup chain into shorter series.

Restore a backed up file You can recover individual VM guest OS files from VM backups.

During file-level recovery, Veeam Backup & Replication does not extract the VM image from the backup file. Instead, it performs the following actions:

• For Microsoft Windows VMs, Veeam Backup & Replication publishes virtual disk files from the backup directly into the Veeam backup server file system with the help of Veeam's proprietary driver.

• For VMs with other OSes, Veeam Backup & Replication deploys an FLR appliance, and mounts virtual disks to this appliance.

After VM disks are mounted, use the Veeam Backup Browser or Microsoft Windows Explorer to copy files and folders to the local machine drive, save them in a network shared folder, or point applications to restored files and work with them as usual.

This section describes the basic steps to restore files on a Windows VM. The “Restoring VM Guest OS Files” section of the Veeam Backup & Replication User Guide provides more details.

1. Open the Backup & Replication view.

2. Click Backups. Expand the backup job in the working area, right-click a necessary VM in the corresponding backup job and choose Restore guest files (Windows) or Restore guest files (other OS).

3. At the Restore Point step, select the necessary restore point.

Veeam Backup & Replication configuration - NFS Configure Veeam Backup & Replication to use the Data Domain system as a backup target, perform a test backup, and restore a backed up file in a Linux/UNIX environment.

Configure an NFS folder as a backup target You can store backups on an NFS export mounted from the Data Domain system to an intermediate Linux system.

The intermediate Linux system addresses a Veeam Backup & Replication support requirement for NFS shares. Veeam’s vPower NFS service prohibits explicit connectivity to NFS shares, and Microsoft Windows systems are not optimized for native NFS connectivity. EMC recommends this configuration for both VMware vSphere and Microsoft Hyper-V environments.

The EMC Linux System Tuning Guide, available on EMC Online Support, provides more specific information for configuring NFS on the Data Domain system.

Veeam Backup & Replication configuration - DD Boost

Configure Veeam Backup & Replication to use the Data Domain system with DD Boost as a backup target, perform a test backup, and restore a backed up file.

Configure the Data Domain system with DD Boost as a backup target Veeam Backup & Replication provides the ability to assign the backup repository role to EMC Data Domain storage systems with DD Boost. Veeam Backup & Replication supports the following DD Boost features:

• Distributed Segment Processing

• Advanced Load Balancing

• Link Failover

• Virtual Synthetics

To support the DD Boost technology, Veeam Backup & Replication uses the following Data Domain components to support the use of DD Boost:

• DD Boost server, the target-side component running on the Data Domain storage system.

• DD Boost library, the source-side component integrated with Veeam Backup & Replication.

The DD Boost library is embedded into the Veeam Data Mover Service setup. When you add a Microsoft Windows server to Veeam Backup & Replication, the DD Boost Library is automatically installed on the server along with the Veeam Data Mover Service.

Veeam Backup & Replication uses the DD Boost library deployed on a gateway server to communicate with the Data Domain system. The gateway server is a backup infrastructure component that bridges the Veeam backup server and the Data Domain system. The gateway server must meet the following requirements:

• Added to Veeam Backup & Replication, and has the DD Boost Library and Veeam Transport Service deployed.

• Has access to both the Veeam backup server and the Data Domain storage system.

The gateway server is selected when you assign the role of the backup repository to the Data Domain system. You can define the gateway server explicitly or instruct Veeam Backup & Replication to select it automatically.

EMC Data Domain and Veeam Bac kup & Rep lic a tion v9.5 Integra tion Guide

Limitations and restrictions • The Data Domain system must have DD OS 5 .4 or later installed.

• The DD Boost license must be installed on the Data Domain system.

• To work with EMC Data Domain, Veeam Backup & Replication uses a gateway server — a proxy Microsoft Windows machine. The gateway server that you plan to use must be added to the backup infrastructure.

If the Data Domain system does not meet these requirements, you can add it as a CIFS share or in Direct NFS access mode. In this case, Veeam Backup & Replication will not use the DD Boost technology to work with EMC Data Domain.

• The length of forward incremental and forever forward incremental backup chains that contain one full backup and a set of subsequent incremental backups cannot be greater than 60 restore points. To overcome this limitation, schedule full backups (active or synthetic) to split the backup chain into shorter series.

• If you connect to the Data Domain system over Fibre Channel (FC), you must explicitly define the gateway server to communicate with the Data Domain system. Use a Microsoft Windows server added to Veeam Backup & Replication with FC access to the Data Domain system as a gateway server.

• Data Domain requires at least 1 Gbps network and 0% packet data loss between the gateway server and the Data Domain system. Without that, stable operation of the Data Domain system cannot be guaranteed.

• Select Automatic selection if a high-speed network connection between the source datastore and the Data Domain system is available. In this case, Veeam Backup & Replication automatically selects a Microsoft Windows server to use as a gateway server. The gateway server is picked per job session. Veeam Backup & Replication may use one gateway server for one job session and another gateway server for another job session.

• Select The following server, and choose a gateway server manually if you perform backup over WAN or slow connections. The selected gateway server must have a direct access to the Data Domain system.

9. In some cases, the automatic selection mechanism may cause problems as Veeam Backup & Replication may use different gateway servers for different job sessions.

For example, during one job session, Veeam Backup & Replication may use a 64-bit gateway server to create a backup file. If during the next job session Veeam Backup & Replication uses a 32-bit gateway server, Veeam Backup & Replication will fail to open the backup file on the backup repository. Explicitly define the gateway server on which the target transport service will be deployed to avoid this issue.

Configure a tape media pool Veeam Backup & Replication uses logical tape containers called media pools to organize and administrate tapes.

There are three types of media pools:

• Service media pools are used to automatically sort tapes and manage free tapes intended for writing data. Service media pools are created automatically. You cannot create or edit them.

• Custom media pools are used as target destinations for tape jobs except GFS tape jobs. To archive data, you need to create at least one custom media pool manually.

• GFS media pools are used to create GFS (Grandfather-Father-Son) tape archives. GFS schemes keep one backup per 4 tiers: weekly, monthly, quarterly and yearly. You need to create one or more GFS media pools manually.

To create a custom media pool:

1. Select Tape Infrastructure > Media Pools > Add Media Pool.

2. At the Name step, specify a name and basic description for the media pool.

Figure 48. Creating a media pool

3. At the Backup Files step of the wizard, select backups that you want to archive to tape with the created job.

Click Add and select the necessary backups. You can choose backups from the following sources:

• Backup jobs. You can select backups from available backup jobs. When a backup to tape job is run, Veeam Backup & Replication will search and archive restore points from the backups created by the selected backup jobs. If you choose to link to a backup job, Veeam Backup & Replication will update the secondary target settings for the backup job.

In the same backup to tape job, you can combine backup jobs for different platforms (VMware vSphere, vCloud Director, Microsoft Hyper-V, Veeam Agent for Windows or Veeam Agent for Linux).

A backup copy job can be a source for the tape job as well. The tape job copies the full backup produced by the backup copy job once, and then only the new increments. Note that the tape job cannot process the last (active) increment until the next one is produced.

• Backup repositories. Using this option, you can select whole backup repositories. When a backup to tape job is run, Veeam Backup & Replication will search and archive restore points from all backups stored in the chosen backup repositories.

If you choose to archive data from backup repositories, the backup to tape job will process only the backups that were created with backup jobs configured on this Veeam backup server. Imported backups and configuration backups will be skipped from processing.

5. Click the Pick proxy to use link to select backup proxies over which VM data must be transported to the source datastore. You can assign backup proxies explicitly or instruct Veeam Backup & Replication to automatically select backup proxies.

If you choose Automatic selection, Veeam Backup & Replication will detect backup proxies that are connected to the source datastore and will automatically assign optimal proxy resources for processing VM data.

During the restore process, VMs are processed simultaneously. Veeam Backup & Replication checks available backup proxies. If more than one backup proxy is available, Veeam Backup & Replication analyzes transport modes that the backup proxies can use for writing data to target, current workload on these backup proxies, and selects the most appropriate resources for VMs processing.

If you choose Use the selected backup proxy servers only, you can explicitly select backup proxies that will be used for restore. It is recommended that you select at least two proxies to ensure that VMs are recovered should one of backup proxies fail or lose its connectivity to the source datastore during restore.

6. Select the Restore VM tags check box if you want to restore tags that were assigned to the original VM, and assign them to the restored VM. Veeam Backup & Replication will restore the VM with original tags if the following conditions are met:

The VM is restored to its original location.

The original VM tag is still available on the source VMware vCenter Server.

10. At the Datastore step of the wizard, specify the destination datastore. This step is available if you have chosen to change the location and settings for the restored VM.

You can place an entire VM to a particular datastore or choose to store configuration files and disk files of the restored VM in different locations. To specify a destination datastore:

Select a VM in the list and click Datastore. To apply changes in bulk, select several VMs in the list and click Datastore.

Point to a datastore where VM files must be stored.

If configuration and disk files of the VM must be placed to different datastores:

Expand the VM in the list.

Select the necessary file type and click Datastore.

Select a datastore where the selected objects must be stored.

By default, Veeam Backup & Replication preserves the format of restored VM disks. If disks of the original VM are provisioned as thick, Veeam Backup & Replication will restore the VM from the backup with thick disks. If necessary, you can change the disk format of a restored VM.

Expand a VM in the list and select the disk and click Disk Type. In the Disk Type Settings section, choose the format that will be used to restore virtual disks of the VM: same as the source disk, thin or thick. Note that disk format change is supported only for VMs with Virtual Hardware version 7 or later.
