snapimage iag 2.0.book Page 12 Monday, June 16, 2008 9:00 AMIntroductionNetWorker module for SnapImage overviewThe NetWorker Module for SnapImage is a high-performancestorage solution that backs up and recovers high-density file systemsacross a LAN or SAN. It is based on the Network Data ManagementProtocol (NDMP) and provides full-image, block-level backups andrecoveries, allowing large amounts of data to be backed up quickly,which reduces the backup window. The SnapImage software backsup high-density file systems faster than traditional file-based backupsystems. It supports full backups as well as differential backups,which back up only the blocks that have changed since the last fullbackup. It can recover data at the block level, and also can recoverspecific files and directories at the volume level. Combined with theNetWorker software, the SnapImage module provides a complete,reliable, and efficient storage management solution.To keep file systems available to users, the software uses snapshottechnology that creates a frozen (or snapshot) view of the file systemsto be backed up. During a backup, the SnapImage software backs upthe snapshot to media. Any changes to blocks on the file system thatoccur during the backup are intercepted by the write intercept driver.Once the backup is complete, the driver copies the blocks that havechanged to the SnapImage cache device before it allows the changesto be committed to the file system.The SnapImage software is installed on all SnapImage clients that theNetWorker server backs up. The NDMP TapeServer is a requiredproduct that must be installed and licensed on the SnapImage clientin addition to the SnapImage software. If storage devices are attachedto a remote host, then the NDMP TapeServer must be installed andlicensed on the SnapImage client and on the host with the storagedevices attached.Note: The NetWorker server, NetWorker License Manager, and NDMPTapeServer are separate NetWorker products that must be installed andenabled in addition to the SnapImage software. EMC NetWorkerInstallation Guide Release 7.0 Microsoft Windows Version provides moreinformation on licensing NetWorker products.12EMC NetWorker Module for SnapImage Release 2.0 Installation and Administration Guide
snapimage iag 2.0.book Page 13 Monday, June 16, 2008 9:00 AMIntroductionSnapImage featuresThe SnapImage software provides the following features: Fast data backup and recoveryFull, block-level image snapshot technology significantly reducesbackup and recovery time compared with traditional, file systembackup and recovery methods. Flexible backup schedulingThe SnapImage software allows operators full flexibility inscheduling differential and full backups. A differential backuponly backs up blocks that have changed since the last full backup. Directory and file-level restoresIf it is not necessary to restore a complete file system, users canselect specific directories and files to restore. Local and remote NDMP storage device supportSnapImage clients can be configured to support locally attachedand remote storage devices. The criteria for setting up local orremote tape device support depends on system environments,storage requirements, and operational procedures.SnapImage software in a SAN environmentThe SnapImage product supports SAN environments. Additionally,depending on the system environment, a LAN is required in thefollowing configuration setups: If the SnapImage client and NetWorker server are installed onseparate hosts. The LAN transports commands, messages, andother information between the two systems. If the NDMP TapeServer is installed on a remote host. The LANtransmits data and provides communications between theSnapImage client and the remote NDMP TapeServer storagenode.Note: The storage node must be installed with the NetWorker NDMPTapeServer Release 2.0 Windows version.SnapImage features13
snapimage iag 2.0.book Page 14 Monday, June 16, 2008 9:00 AMIntroductionSnapImage software in a cluster environmentThe SnapImage product can exist in a cluster environment. Thesoftware can co-exist with the following cluster products: Microsoft Cluster Server (MSCS) for Windows 2000 AdvancedServer, Service Packs 1 and 2 EMC Automated Availability Manager, release 4.8.1, andWindows 2000In a cluster environment, backup level 0 and backup level 1backups are supported. In the event of a cluster failover during abackup operation, the SnapImage software then performs a fullbackup from the failover node.Note: Multiple licenses are required if a cluster environment has storagenodes or dedicated storage nodes. Each storage node in the cluster must beinstalled with a separate NDMP TapeServer license.Distributed file system supportA distributed file system (DFS) allows operators to access multipleshared volumes that are on different network servers from a singlelocation, without requiring specific server information where thevolumes are located.The following limitations exist for DFS in a SnapImage environment: Only primary volumes that are locally mounted are backed up;backups of DFS replicas are not. Operating system (OS) partitions containing the system registryand DFS root must be backed up with the NetWorker clientsoftware, not the SnapImage software. The DFS root and the registry must be backed up at the sametime to ensure consistency. The active directory for domain-based DFS trees must bebacked up with the NetWorker client. If the DFS root is not on the OS partition, the partition onwhich it is located must be added to the NetWorker clientconfiguration containing that partition. This way, the twopartitions can be backed up at the same time.14EMC NetWorker Module for SnapImage Release 2.0 Installation and Administration Guide
snapimage iag 2.0.book Page 15 Monday, June 16, 2008 9:00 AMIntroduction All DFS root and registry backups must be full backups.Differential DFS backups are not supported. The registry and the DFS root partition must be restored fromthe same saveset. When you perform a directed restore of a DFS partition to a hostother than the original host, the DFS link to the partition will notbe restored. You must use the DFS console to create a new DFSlink.Multipathing support with the SnapImage softwareThe SnapImage module supports multipathing software.Multipathing allows two or more paths to transfer data concurrently,increasing backup and recovery speed and protecting against pathfailure. Multipathing provides load balancing by switching the datatransfer to the path with the least traffic. In addition, if one path fails,the data transfer is switched to the functioning path.The following multipathing software is certified for use with theNetWorker Module for SnapImage: EMC PowerPath , version 3.0.0 HP StorageWorks Secure Path Release 4.1Additional Windows 2000 Server and Windows 2000 advanced Server featuresThe SnapImage software supports the following additional recoveryfeatures specific to Windows 2000 Server and Advanced Server: Savesets can be recovered to a mount point path location. Drives can be basic or dynamic. Existing SnapImage drives can beupgraded from basic to dynamic. Most new and enhanced NTFS file system features areincorporated into SnapImage functions.Note: You should not recover an NTFS file system file or directory to a fileallocation table (FAT) partition. The multinamed data streams and accesscontrol lists (ACLs) are not successfully restored. Only the file data and basicdirectory information and attributes are restored.SnapImage features15
