22 Overview NetWorker Module for Microsoft Applications The EMC NetWorker Module for Microsoft Applications (NMM) works with Microsoft Volume Shadow Copy Service (VSS) technology to provide snapshot backup and recovery services for file systems, and application, and operating system data. The NMM client allows for the creation of point-in-time snapshot data. A snapshot can be retained on storage volumes for quick access. One can also perform a rollover of a snapshot to a traditional backup medium such as a tape, file type device, or advanced file type device. Data can be recovered either from a snapshot or from the backup. NetWorker Module features This NetWorker Module can be set up in a LAN-based or LAN-free environment. NMM provides the following features: Support for the following topologies: Simple LAN-based configuration on page 25 LAN-based configuration with a proxy client on page 26 LAN-free configuration on page 27 Support for several types of backup and recovery, depending on the types available for the given application or operating system: Instant backup with or without rollover on page 34 Nonpersistent rollover backup on page 34 Serverless backup on page 34 Conventional recovery on page 36 Instant recovery on page 36 Rollback recovery on page 36 Deduplication support for most of the Microsoft applications and Windows operating systems that are supported by NMM: Windows OS, application, and configuration support on page 74 provides detailed lists of applications and versions supported. For the NetWorker server, NetWorker Release 7.5 SP1 or later is required. For the Avamar server hardware, Avamar Axiom v4.0.2 or later is required. Application support: Microsoft Exchange Server 2007 Microsoft Exchange Server 2003 Microsoft SQL Server 2008 Microsoft SQL Server 2005 Microsoft Office SharePoint Server 2007 Microsoft SharePoint Portal Server 2003 Windows SharePoint Services 3.0 Windows SharePoint Services 2.0 Microsoft System Center Data Protection Manager EMC NetWorker Module for Microsoft Applications Release 2.2 Administration Guide

Privileged user-level access All NMM users must have administrator-level privileges for all resources they access: NetWorker server Each NetWorker Module for Microsoft Applications (NMM) client machine All Microsoft applications protected by NMM, such as: Windows Server Data Protection Manager (DPM) SharePoint Server SQL Server Exchange Server Network domains Storage servers Windows and Microsoft application updates Keep NMM client machines current with Microsoft Windows updates for the operating system, as well as updates and hotfixes for each installed Microsoft application protected by NMM. Otherwise NMM may not function correctly, or backup or recovery may fail. For example, the NMM UI may fail if the latest.net updates are not installed. NetWorker Module for Microsoft Applications 23

24 Overview Supported configurations This section describes the basic configurations in which the NMM client is supported. Supported NetWorker Server hosts The NMM client supports NetWorker Server or later and NetWorker Storage Node or later on the following hosts: AIX HP-UX (PA-RISC) Solaris (SPARC) Windows Linux (NetWorker Server 7.4 SP3 or later and NetWorker Storage Node 7.4 SP3 or later) The NMM client supports Internationalization (I18N). NetWorker 7.4 SP3 or later is required for Microsoft Office SharePoint 2007 granular protection. This release of NMM supports NetWorker cloning and staging to create and manage additional copies of save sets. This NMM support requires NetWorker 7.5 or later. The EMC NetWorker 7.5 Administration Guide provides details for cloning and staging. The following NetWorker features are not supported: Localization (L10N) Installation of dedicated storage node on NMM client host. Note: NMM does support proxy storage node, as described in LAN-free configuration on page 27.

25 Overview System state recovery, file servers, and operating system roles including Active Directory, DHCP, and Terminal Services GUID Partition Table disks: No disk size limit on Windows environments with CLARiiON storage (SnapView clone, SnapView snap, and SAN Copy technologies only) Disk size limit of less than 2 TB on Windows environments with Symmetrix storage Note: The following Windows Server versions are not supported: Windows IA64 editions. In addition, the following Windows features are not supported: BitLocker encryption LAN-based Proxy Client or LAN-free backups, if dynamic disks are used VSS Hardware Providers with Windows dynamic disks Microsoft Software Shadow Copy provider to perform persistent snapshots of clustered disks Windows Automated System Recovery (ASR) Note: Windows Storage Server Single Instance Storage (SIS) is supported, but recoveries will recover file data for all duplicate files. Data will not be lost if there is sufficient disk space to hold the duplicate copies. The EMC Information Protection Software Compatibility Guide contains additional and the most up-to-date information about NMM compatibility. Simple LAN-based configuration Figure 1 on page 26 shows a simple LAN-based configuration with a storage area network. In a LAN-based configuration, the production data is stored on a storage area network (SAN) or direct-attached storage (DAS). The data path to the NetWorker storage node devices is over a LAN. The application server that is being protected has the NMM client installed. The data moves as follows: 1. The NetWorker Server, which must be release or later, initiates the process by contacting the application server where the NMM client software is installed. 2. The application server with the NMM client software creates a snapshot of the data on the storage volume. Note: In Figure 1 on page 26, snapshots are represented by S1 through S5. 3. The application server with the NMM client software uses a snapshot in primary storage to transfer the data over the LAN and into a conventional backup medium such as a file type disk, advanced file type disk, or tape. Supported configurations 25

Both the application server and the proxy client have the NMM client installed. Note: The application server and the proxy client must use the same version, NetWorker Module for Microsoft Applications release 2.2. If NMM 2.2 is installed on either the application server or the proxy client machine, then the other machine must also use NMM 2.2. Backup and recovery will fail if NMM 2.2 is used on one of these machines, and an earlier version of NMM is used on the other. A proxy client is a host that acts as a remote data mover (DM) when snapshots are rolled over to a conventional backup medium. A proxy client frees resources on the application server. When a backup operation uses a proxy client, it is known as a severless backup. The data moves as follows: 1. The NetWorker server initiates the process by contacting the application server where the NMM client software is installed. 2. The application server with the NMM client software creates a snapshot of the data on the storage volume. Note: In Figure 2 on page 27, snapshots are represented by S1 through S5. 26 EMC NetWorker Module for Microsoft Applications Release 2.2 Administration Guide

The NMM client is installed on the application server. The proxy client is installed on the NetWorker storage node. You can set up a NetWorker storage node release or later as a proxy client to avoid the network traffic that is generated when a snapshot is rolled over to a conventional backup medium. Network traffic is avoided because both the conventional backup device and the snapshot are directly attached to the storage node. Note: Install the proxy client software by using the NMM client software package. The data moves as follows: 1. The NetWorker server initiates the process by contacting the application server where the NMM client software is installed. 2. The application server with the NMM client software creates a snapshot of the data on the storage volume. Note: In Figure 3 on page 28, snapshots are represented by S1 through S5. Supported configurations 27

28 Overview 3. The snapshot is made visible to the proxy client. 4. The proxy client, in this case the storage node, uses a snapshot in primary storage to transfer the data into a conventional backup medium such as a file type disk, advanced file type disk, or tape. The NetWorker server and the application server communicate through the LAN. However, the data itself is not transferred across the LAN because the conventional backup medium is attached directly to the NetWorker storage node.

29 Overview The VSS snapshot creation process Microsoft Volume Shadow Copy Service (VSS) acts as a coordinator among the following three components that create, modify, back up, and recover data: Requestors Requestors include the NetWorker backup application. Writers Including writers for operating system data, application data such as Microsoft Exchange Server 2003 or Microsoft SQL Server data, and file system volumes such as a D:\ data drive. Providers Providers include the Microsoft VSS software provider or hardware-based providers such as the EMC VSS Provider. In VSS, NetWorker software is a requestor an application that performs the backup and recovery of applications or services. When a requestor performs a backup or recovery, the following occurs: 1. The requestor asks for information from VSS. 2. VSS reviews the request for validity. 3. VSS sends writer data from multiple application and system writers to the requestor. 4. The requestor tells VSS which writers and volumes to include in the snapshot. Each application and service that supports VSS has its own writer, which understands how the application or service works. After the writer signals that it has prepared the data, the following occurs: 1. The VSS software does the following: a. Directs the writer to freeze input/output (I/O) to the selected volumes. b. Queues transactions for later processing. c. Calls a provider to capture the requested data. 2. The provider does the following: a. Captures the prepared data. b. Creates a snapshot that exists side-by-side with the live volume. 3. After the snapshot is created: a. The provider signals VSS, this signal tells the writer to resume activity. b. I/O is released to the selected volumes and any queued writes that arrived during the provider's work are processed. Figure 4 on page 30 illustrates the VSS backup process. The VSS snapshot creation process 29

30 Overview 4. Requestor asks VSS to create snapshot. Requestor 1. NetWorker software (the requestor) asks VSS to enumerate writers and gether their metadata. 2. Writers provide an XML description of backup components and define the recover method. 5. VSS tells the writers to freeze activity. Writer Writer Writer Writer 7. VSS tells the writers to resume activity. Writer 3. VSS asks which providers can support a snapshot for each of the required volumes. 6. VSS tells the providers to create the snapshot of the current state on disk. Microsoft VSS Software Provider EMC VSS Provider (CLARiiON or Symmetrix) Disk 1 Disk 2 Disk 3 Disk 3 GEN Figure 4 VSS backup process Writers Writers provide information about what data to back up, and specific methods for handling components and applications during backup and recovery. They also identify the type of application or service that is being backed up. If a service or application is present on a system but is not active, information from its writer will not be available. Consequently, a writer can appear or disappear from backup to backup. 30 EMC NetWorker Module for Microsoft Applications Release 2.2 Administration Guide

The FTP files are content files, and must be backed up separately. The VSS snapshot creation process 31

32 Overview Providers A provider is used to capture snapshots. One of the following types of providers are available: EMC VSS Hardware Provider, which supports EMC Symmetrix, Symmetrix DMX, and CLARiiON arrays EMC Celerra VSS Hardware Provider, which supports Celerra arrays Dell EqualLogic VSS Hardware Provider, which supports EqualLogic PS Series arrays Microsoft Software Shadow Copy provider IBM SystemStorage DS Open API Package, which supports IBM Storage, which supports IBM Storage System DS6000 and DS8000 The Microsoft Software Shadow Copy provider is a host-based provider that works with any type of storage hardware. The EMC VSS Hardware Provider works with an CLARiiON or a Symmetrix disk array. Some features of the NMM client, such as serverless backup and rollback recovery, are available only with hardware providers such as the EMC VSS Hardware Provider. The NetWorker Module for Microsoft Applications Release 2.2 Installation Guide provides more information about using NMM with a VSS Hardware Provider, including hardware array installation and configuration, and NMM installation and configuration. Note: NMM does not support rollback restore for backups performed by EqualLogic or Celerra hardware. Only conventional restore and snapshot restore are supported for backups performed by EqualLogic or Celerra hardware. Dynamic volume support In Windows Server 2003 and Windows Server 2008: NMM supports snapshots of dynamic volumes that use the Microsoft Software Shadow Copy provider. NMM provides software-based support for: Dynamic volume on a single disk. Dynamic volume spanning multiple disk. NMM does not support dynamic volumes in striping. NMM does not support hardware-based VSS transportable snapshots of dynamic volumes. NMM will attempt to perform a hardware-based VSS transportable snapshot when a proxy backup host is specified by using NSR_DATA_MOVER in the application information field of the Client resource. For example, hardware-based transportable snapshots are not supported when the dynamic volumes are on CLARiiON storage. NMM will attempt to perform the hardware-based snapshot, but the operation will fail during import of the hardware-based snapshot on the proxy backup host.! IMPORTANT Any attempt to take a hardware-based replica of a dynamic volume will fail, and cause instability in the system. 32 EMC NetWorker Module for Microsoft Applications Release 2.2 Administration Guide
