4 Technical white paper Page 4 Executive summary One of the most common challenges for enterprises is dealing with exponential data growth. With growth comes several data management challenges: meeting stringent backup and recovery service-level agreements (SLAs), keeping up the desired recovery point objectives (RPOs) and recovery time objectives (RTOs), and simplifying and enhancing remote office protection. IT organizations are challenged to do more with limited budgets and fewer IT resources. Meeting these pain points requires a paradigm shift towards optimized data protection. As a leader in storage, Hewlett Packard Enterprise is working with Veritas to deliver innovative solutions that modernize data protection for Veritas NetBackup environments to enable complete protection and delivery of the agreed SLAs. The IT industry is undergoing a transformation. Data is growing at unprecedented rates and must be retained longer and accessed instantaneously. Traditional backup and recovery methodologies are too slow and often fail to meet the required business SLAs for today s data center. Adding more data protection devices to manage easing volumes of data leads to system sprawl and eased management complexities. Most data protection technologies in use today have limitations, including incompatible technology silos, restricted scale and performance, untenable SLAs and backup failures, and complex management. To address the limitations of current data protection technologies and provide greater protection, Hewlett Packard Enterprise offers StoreOnce Systems built on breakthrough scale-out architecture and federated deduplication technology developed by Hewlett Packard Enterprise Labs. HPE StoreOnce Systems are specifically designed for automated, hands-free backup that consolidates protection of multiple servers to a single HPE StoreOnce System. HPE StoreOnce deduplication provides more backup data storage in the same footprint with a 10 to 20 times ease, depending on the data being protected and the backup schedule. HPE StoreOnce replication enables cost-effective replication of data to or from remote locations for an additional level of protection. Target audience This document is intended for solution architects, database, backup, system or storage operators, and administrators, who are designing, implementing, and maintaining common backup tasks. It describes the different backup and recovery solutions using HPE StoreOnce OST Plug-in and Veritas NetBackup, provides setup and configuration recommendations and best practices on how to run an effective and efficient backup environment, and describes backup performance and recovery best practices. Readers of this Technical White Paper should have a functional understanding of HPE StoreOnce Systems backup concepts and technologies, as well as Veritas NetBackup. This is not intended to replace any of the existing documentation. For other HPE StoreOnce Systems documentation, refer to Introduction to HPE StoreOnce OST Plug-in for Veritas NetBackup The HPE StoreOnce System has a tight integration with Veritas NetBackup enabled by the HPE StoreOnce OST Plug-in for Veritas NetBackup. This plug-in allows NetBackup-managed movement of deduplicated data across the enterprise, from one HPE StoreOnce System to another. This high efficiency is enabled by the HPE StoreOnce Catalyst interface, which offers multiple advantages for backup to disk compared to traditional NAS and virtual tape interfaces. HPE StoreOnce Catalyst software was developed to dramatically improve the performance, function, and integration of backup applications such as Veritas NetBackup. HPE StoreOnce Catalyst delivers deduplication on an appliance server, media server, or dedicated appliance. Because it uses the same deduplication algorithm globally, data can be moved between platforms without rehydration. HPE StoreOnce Catalyst allows better utilization of advanced, disk-based storage solutions while easing efficiency and performance. HPE StoreOnce OST Plug-in for Veritas NetBackup offers you: Better performance Achieve significantly enhanced performance by writing to HPE StoreOnce Catalyst compared to traditional disk backup targets. This is achieved by distributing deduplication processing between NetBackup media servers and the HPE StoreOnce System. Simplified management Centrally control data movement by the Veritas NetBackup backup, which allows single console management. Greater flexibility Move data from one site to multiple sites and enable replication across low-bandwidth networks with the bandwidthreducing HPE StoreOnce deduplication.

6 Technical white paper Page 6 Solution components The testing environments exercised different Veritas NetBackup features while implementing the HPE StoreOnce OST Plug-in. Backup and restore throughput and deduplication performance was also tested. Aspects of the backup and restore throughput performance and deduplication performance are: Varying block size Varying rates of data change Weekly full and daily emental backup schedule Disaster Recovery Veritas NetBackup OST feature testing includes: Optimized Duplication (Opt_Dup) Auto Image Replication (A.I.R.) and Targeted Auto Image Replication (T.A.I.R.) Granular Recovery Technology (GRT) Granular Recovery Technology VMware (GRT_VMware) Instant Recovery VMware (IR_VMware) Test Environments The backup and restore throughput performance and deduplication performance testing was performed with the following configuration: HPE ProLiant DL380 G7 Server Windows Server 2012 R2 HPE ProLiant DL380 G7 Server Red Hat Enterprise Linux 7.2 HPE StoreOnce 6500 System running software revision 3.16 HPE StoreOnce 4900 System running software revision 3.15 HPE MSA 2040 SAN Storage system running software revision GL105P003 HPE StoreOnce OST Plug-in version Veritas NetBackup version 8 The Veritas NetBackup feature testing was performed with the following configuration: HPE ProLiant DL380 G8 Server Windows Server 2012 R2 HPE ProLiant DL380 G7 Server Red Hat Enterprise Linux 7.2 HPE StoreOnce 6600 System running software revision 3.16 HPE StoreOnce 2900 System running software revision 3.15 HPE 3PAR StoreServ 7400C Storage System using FW build EMU2 HPE StoreOnce OST Plug-in version vcenter Server 6 running on an HPE BL460c with Windows Server 2012 R2 ESXi6 host ProLiant DL380 G7 VM Windows Server 2008 R2 VM Red Hat Enterprise Linux 6 Veritas NetBackup version 8

7 Technical white paper Page 7 Notes 100 GB of non-compressible, non-dedupable data was used as the dataset for these tests. Unless noted otherwise, 1% data change was performed between backups. For block size testing, 256 KB, 512 KB and 1024 KB blocks were tested. The block size was modified in Veritas NetBackup using the SIZE_DATA_BUFFERS configuration setting. The default setting is 256 KB. Network The HPE ProLiant servers and VMs were all connected via a 1 GbE interface for management traffic. For Catalyst over Ethernet and NAS, the 10 GbE interface was used for data traffic to the HPE StoreOnce Systems. For Catalyst over Fibre Channel and VTL, the 8 Gb FC interface was used for data traffic to the HPE StoreOnce Systems. HPE StoreOnce Systems The HPE StoreOnce Systems used Low Bandwidth Primary Transfer Policies, also known as source-side deduplication. Low Bandwidth leverages HPE StoreOnce Catalyst source-side deduplication technology. This is the preferred option for copying backups directly to remote HPE StoreOnce Systems, and it achieves the highest level of aggregated backup throughput, both on and off site. Figure 2 shows the Catalyst Store configuration. Figure 2. Low-bandwidth catalyst store configuration HPE StoreOnce Catalyst Plug-in for NetBackup With version and above, the HPE StoreOnce Catalyst Plug-in for NetBackup installation has been enhanced to provide a more user-friendly experience regarding the use of Content Aware Backups and optimization settings for network compression and network checksums. Enabling or disabling these features will have an impact on backup and restore throughput and deduplication performance.

In Windows environments, the installation setup displays questions, as shown in Figure 3 and Figure 4. Note The new Content Aware Backups feature is incompatible with existing HPE StoreOnce Catalyst stores. Figure 3.

11 Technical white paper Page 11 Figure 6. HPE StoreOnce Catalyst Plug-in for NetBackup Setup showing prompt for enabling/disabling network compression and network checksums The HPE StoreOnce Catalyst Plug-in for NetBackup version also uses a new installation path and new configuration file name for Windows and Linux, HP-UX, AIX, and Solaris operating systems that is different from previous versions of the Plug-in. For Windows environments: The new installation path is %ProgramFiles%\Hewlett Packard Enterprise\StoreOnce. The new configuration file is located in %ProgramFiles%\Hewlett Packard Enterprise\StoreOnce\isvsupport\OST\config. For Linux, HP-UX, AIX, and Solaris environments: The new path is /usr/openv/hpe/ost. The new configuration file is located in /usr/openv/hpe/ost/config. The new configuration file name is plugin.conf.

12 Technical white paper Page 12 Backup throughput performance and deduplication ratios Testing was performed to evaluate the backup throughput performance and deduplication ratios with Veritas NetBackup and HPE StoreOnce Systems. The initial backup will typically show a slower speed, which is normal behavior across all target types. This is because the initial data has to be chunked, compressed, and sent to the HPE StoreOnce System. Notes Backup and restore performance varies between HPE StoreOnce target types. All tests used a single stream of backup data to the HPE StoreOnce Catalyst stores. Catalyst over Ethernet (CoE) and Catalyst over Fibre Channel (CoFC) backup testing Varying Block Size CoE/CoFC When testing backups to Catalyst stores on the HPE StoreOnce System, backup throughput performance was higher for RHEL versus Windows, with 1024 KB CoFC showing the fastest throughput.

Granular Recovery Technology (GRT) Granular Recovery Technology VMware (GRT_VMware) Instant Recovery VMware (IR_VMware) Optimized Duplication and Whole Image Optimized Duplication With optimized duplication, backup images on a storage server can be replicated from one HPE StoreOnce System to another HPE StoreOnce System that resides in the same NetBackup domain. The ability to duplicate backups to storage in other locations, often across various geographical sites, helps facilitate data protection and disaster recovery. Optimized Duplication transfers data in 256 KB chunks. Whole Image Optimized Duplication uses the storage unit's Maximum fragment size to transfer an entire NetBackup image fragment in a single operation.

24 Technical white paper Page 24 Optimized Duplication is configured using a Storage Lifecycle Policy (SLP) in NetBackup. The SLP manages both the backup jobs and the duplication jobs. For the backup destination, the Storage Unit of the local or primary HPE StoreOnce System is the target for the backups. For the Duplication destination, the Storage Unit of another HPE StoreOnce System (secondary) is selected. Then the backup policy is configured to use the SLP. Figure 18 shows the Storage Lifecycle Policy screen where the backup and duplication operations are defined. Note The minimum HPE StoreOnce software version for optimized duplication to a CoFC store is 3.16.x. Figure 18.

26 Technical white paper Page 26 Auto Image Replication (A.I.R.) and Targeted Auto Image Replication (T.A.I.R.) The Auto Image Replication (A.I.R.) feature in NetBackup addresses the site-to-site replication challenge by allowing storage lifecycle policies to duplicate selected images between NetBackup Master Domains. The primary purpose of Auto Image Replication is to create off-site copies of critical backups to protect against site loss. NetBackup A.I.R. relies on tpman, a Hewlett Packard Enterprise proprietary tool, to create replication topologies between logical storage units. The HPE StoreOnce Catalyst Plug-in uses this information to initiate automatic replication of data. tpman supports m:n NetBackup Domain replication topologies for A.I.R. operation. A.I.R. comes in the following configurations: Untargeted A.I.R.: The HPE StoreOnce Catalyst Plug-in broadcasts the images based on the m:n topology and you cannot choose the replication targets. Targeted A.I.R.: Targeted A.I.R. presents the set of available targets for an A.I.R. operation. You can use the HPE StoreOnce Catalyst Plug-in to send data to selective targets rather than a broadcast. Note The tpman tool is still necessary to create the replication topology. Configuring replication topologies Hewlett Packard Enterprise provides a command line tool (tpman) for configuration of replication topologies between logical storage units. This tool provides the capability to add, remove, and show replication topologies between logical storage units and it is installed with the OST Plug-in in the following locations: Windows: %ProgramFiles%/Hewlett Packard Enterprise/StoreOnce/isvsupport/OST/bin/tpman.exe Linux, HP-UX, AIX, and Solaris: /usr/openv/hpe/ost/bin/tpman Adding replication topologies Add a replication topology between the source and the target logical storage units with the following command: # tpman --add --source <sts>/<lsu> --target <sts>/<lsu> [--client <client_identifier>] Where: <sts> is the storage server address (IPv4, IPv6, Catalyst over Fibre Channel identifier, or FQDN). <lsu> is the logical storage unit. (This is the HPE StoreOnce Catalyst store name.) <client_identifier> is the required HPE StoreOnce Catalyst Client Identifier when HPE StoreOnce Catalyst Client credentials are enabled. tpman will prompt for the password when the command is executed. Note The Catalyst over Fibre Channel identifier can be found on the HPE StoreOnce System GUI under StoreOnce StoreOnce Catalyst Fibre Channel Settings. The logical storage unit or HPE StoreOnce Catalyst store name can be found on the HPE StoreOnce System GUI under StoreOnce StoreOnce Catalyst Stores. Example: # tpman --add --source /COE-PRIMARY --target /COE-SECONDARY --client gzw12a.ebs.net

27 Technical white paper Page 27 Figure 20 shows an example tpman command structure where the source HPE StoreOnce System and target HPE StoreOnce System are defined. Figure 20. tpman example showing the replication topology setup between the source and target logical storage units Granular Recovery Technology (GRT) and VMware The OST Plug-in supports Veritas s NetBackup Granular Recovery Technology (GRT) feature that enables select items from database backups to be restored on clients. NetBackup GRT leverages Network File System, or NFS, to read individual objects from a database backup image or a VM snapshot backup. Specifically, the NetBackup client uses NFS to extract data from the backup image on the NetBackup media server. The NetBackup client uses Client for NFS to mount and access a mapped drive that is connected to the NetBackup media server. The NetBackup media server handles the I/O requests from the client through NBFSD. NBFSD is the NetBackup File System (NBFS) service that runs on the media server. NBFSD mounts the backup image as a file system folder on the NetBackup client over a secure connection. NetBackup uses GRT and NFS to recover the individual objects that reside within a backup image, such as: A user account from an Active Directory database backup messages or folders from an Exchange database backup A document from a SharePoint database backup An individual file from a VM snapshot backup To restore individual items from a backup that uses GRT, you must enable Services for Network File System (NFS). To enable Services for NFS, please see the Microsoft TechNet article at: To install Services for NFS components: 1. Click Start, point to Administrative Tools, and then click Server Manager. 2. In the left pane, click Manage Roles. 3. Click Add Roles. The Add Roles Wizard appears. 4. Click Next. The Select Server Roles options appear. 5. Select the File Server check box, and then click Next. 6. The File Server screen appears. Click Next to view the Role Services options. 7. Select the Services for Network File System (NFS) check box, and then click Next. 8. Confirm your selection and click Install. 9. When the installation completes, the installation results will appear. Click Close to complete the installation.

29 Technical white paper Page 29 Optimization options (VMware) Enable file recovery from VM backup This option allows restore of individual files from the backup. With or without this option, you can restore the entire virtual machine. You can also use this option for emental backups: in the policy schedule, select differential emental backup or cumulative emental backup. To perform a VMware backup to a deduplication storage unit, select the Enable file recovery from VM backup option. Figure 22 shows the Enable file recovery from VM backup option under the VMware tab in the policy properties. Figure 22. Enable file recovery from VM backup option

30 Technical white paper Page 30 Instant Recovery VMware (IR_VMware) NetBackup can recover a virtual machine almost instantly, without waiting to transfer the virtual machine's data from the backup. NetBackup starts the virtual machine directly from the backup image and makes it accessible to users on the target ESX host immediately. You can copy files (including vmdk files) without restoring the entire virtual machine. Access and restore individual files and folders from any type of OS and then delete the virtual machine. (Note for Windows or Linux: Instead of instant recovery, use the Enable file recovery from VM backup option and restore individual files with the NetBackup Backup, Archive, and Restore interface.) By using the Enable file recovery from VM backup option (see Figure 22 above), individual files can be selected for restore using the NetBackup Backup, Archive and Restore interface. Figure 23 shows an example of the NetBackup Backup, Archive and Restore interface with a single file selected for restore from a VMware backup. Figure 23. NetBackup Backup, Archive, and Restore interface The virtual machine is started directly from the backup image residing on the HPE StoreOnce Catalyst store and is available in seconds or minutes. The startup time depends on the network speed and storage speed, not on the size of the virtual machine. The NetBackup CLI command nbrestorevm is used for IR_VMware. This CLI process has been simplified and only requires the use of few options. To initiate Instant Recovery (activate the virtual machine). Options without brackets are required. # nbrestorevm -vmw -ir_activate -C vm_client -temp_location temp_location_for_writes [-S master_server] [-vmpo] [-vminstanceid] [-vmsn] [-vmkeephv] [-vmserver vm_server] [-vmproxy vm_proxy] [-s mm/dd/yyyy [HH:MM:SS]] [-e mm/dd/yyyy [HH:MM:SS]] [-R absolute_path_to_rename_file] [-disk_media_server media_server]

31 Technical white paper Page 31 Note Only -vmw, -ir_activate, -C, and -temp_location are required. If the other options are not specified, NetBackup automatically supplies values for those options from the backup. In most cases, if you do not restore the virtual machine to a different location, you can omit the bracketed options. Table 1. Options on the nbrestorevm command for Instant Recovery Option Description nbrestorevm -vmw Command to initiate Instant Recovery. Indicates the type of virtual machine to restore (VMware). -C virtual_machine The name of the virtual machine as identified in the backup. For example, if the policy backed up the virtual machine by its host name, specify that host name. -ir_activate -temp_location temporary_datastore Note: If a virtual machine with the same name already exists on the target ESX host, the command fails. You can change the display name of the virtual machine in vcenter. As an alternative, use the -R option on nbrestorevm to change the display name or location of the restored virtual machine. Starts the restore by mounting the backup image of the virtual machine as an NFS datastore. The datastore becomes accessible to the ESX host where the virtual machine is to be restored. A temporary datastore on the ESX server where all writes occur until the virtual machine is restored. All writes occur on this datastore until Storage vmotion is complete or until you are finished with the virtual machine (such as for troubleshooting). Note: This datastore must exist before you run nbrestorevm. -vmpo Turns on the virtual machine after the restore. An example nbrestorevm command: # nbrestorevm vmw ir_activate C vm001 temp_location temp_loc5 -vmpo This command starts the restore by mounting the backup image of the virtual machine host vm001 as an NFS store. The temporary location temp-loc5 is a temporary datastore on the ESX server where all writes occur. For more details regarding IR_VMware, please see the Veritas NetBackup for VMware Administrator's Guide at: Disaster Recovery with HPE StoreOnce Systems and Catalyst HPE StoreOnce Systems have the ability to replicate data to a remote facility for disaster recovery purposes using replication. The combination of Veritas NetBackup and HPE deduplication-enabled Low-Bandwidth Replication (LBR) between HPE StoreOnce Systems offers a solution to protecting servers in remote offices by allowing data to be replicated in a fast, reliable, and automated manner. Data recovery is flexible depending upon the situation or type of failure. One of the key features that HPE StoreOnce Catalyst stores provide is allowing NetBackup to utilize Low-Bandwidth optimized duplication jobs between Catalyst stores. Replicating backup data between HPE StoreOnce Systems is accomplished by properly configuring a backup policy to contain a set of sequential jobs, one being the backup job and the other being an optimized duplication job (or copy). When a backup job completes, the optimized duplication job is executed to the alternate HPE StoreOnce System. In a disaster recovery situation, recovering data from an alternate HPE StoreOnce System is achievable in NetBackup after running an optimized duplication job. Because the NetBackup catalog is aware of all copies, recovery of data from a NetBackup OST-optimized duplicate copy is the same as recovery from another duplicate. Through NetBackup's Backup-Archive-Restore GUI, the OST-optimized duplicate copy can be designated as the primary copy, and then a restore can be initiated. The potential time savings over recovery from a non-ost-optimized duplicate could be significant.

32 Technical white paper Page 32 NAS backup testing Notes NFS was only tested on RHEL. Hewlett Packard Enterprise recommends that you force synchronous data transfer to avoid out-of-order data transmission. NFS does not ensure in-order packet delivery between source and target devices. The NFS device should be mounted using the following options explicitly to mount the HPE StoreOnce System using NFSv3 and force synchronous transfer: # mount t nfs o nfsvers=3,sync,wsize=<size in bytes>,rsize=<size in bytes> x.x.x.x:/nas/<name of remote share> <local mount point> Where x.x.x.x is the IP address of the HPE StoreOnce System. Varying Block Size - NAS When testing backups to NAS shares on the HPE StoreOnce System, backup throughput performance was higher for NFS shares versus SMB shares. NFS restores exhibited better throughput performance than SMB. Figure 24 shows SMB and NFS backup throughput performance with varying block size settings to an HPE StoreOnce 6500 System.

44 Technical white paper Page 44 Disaster Recovery with HPE StoreOnce Systems using NAS/VTL As discussed earlier with Catalyst in Disaster Recovery with HPE StoreOnce Systems and Catalyst, HPE StoreOnce Systems have the ability to replicate data to a remote facility for disaster recovery purposes using replication. In order to setup Replication when using HPE StoreOnce NAS or VTL features, use the Replication and Recovery sections in the StoreOnce GUI. NAS and VTL are both replicated the same way using the Replication options in the HPE StoreOnce GUI. Figure 36 shows the Replication menu item in the HPE StoreOnce navigator menu. Before replication options can be used, the NAS and/or VTL devices must already be created on the HPE StoreOnce System; otherwise, the mappings screens shown in Figure 37 and Figure 38 will not be available. Figure 36. HPE StoreOnce Replication Replication Mappings are created to another HPE StoreOnce appliance in the same network. The connections for NAS and VTL replication are supported only over network and not FC. Figure 37 and Figure 38 show the HPE StoreOnce Replication and Recovery Wizards for NAS (Local Share) and VTL (Local Library) mappings screens. From this point, the Replication Wizard or Recovery Wizard can be started for NAS or VTL, respectively. Figure 37. HPE StoreOnce NAS Replication and Recovery Wizard Figure 38.

Figure 42 shows the Welcome screen for the VTL Recovery Wizard. After finishing the wizard, the new device is created and recovery begins automatically. Note If the data needs to be restored from the replication device, the Mapping between the devices must first be removed. The old VTL device on the source HPE StoreOnce System should be removed and rebuilt or fully erased. Figure 42.
