What does File Server Resource Manager do?With the File Server Resource Manager Microsoft Management Console (MMC) snap-in, you can perform three sets of tasks to manage storage resources on local or remote servers: Quota management. Set soft or hard space limits on a volume or folder tree. You can create and apply quota templates with standard quota properties. File screening management. Define filtering rules that monitor or block attempts by users to save certain file types on a volume or folder tree. You can create and apply screening templates with standard file exclusions. Storage reports management. Generate built-in reports to track quota usage, file screening activity, and patterns of storage use. You can also apply quota and file screening policies when you provision a shared folder, or through a command-line interface.
IT administrators in charge of network storage resources, who want to efficiently distribute these resources by creating quotas IT administrators who want to block certain types of files from being stored in network storage resources IT administrators who want to generate reports to better understand how server storage resources are being utilized User account managers who want to apply storage policies by creating quotas and file screening rules for user folders and shared storage resources
If you are currently using NTFS disk quotas, you will find greater precision in the quota management tools in File Server Resource Manager, as shown in the following table.
The quotas you create in File Server Resource Manager are entirely separate from any NTFS quotas you might have created—the two systems are not designed to work together. However, to migrate from NTFS quotas, File Server Resource Manager provides quota templates that help you recreate your NTFS quota properties. If you plan to use File Server Resource Manager to manage storage resources on a remote server, that server must be running Windows Server 2008 with an instance of File Server Resource Manager. What functionality does this feature provide?You can use File Server Resource Manager in Windows Server 2008 to perform the following tasks: Manage quotas Create, update, and obtain information about quotas, which set a space limit on a volume or folder. When storage reaches predefined levels, send e-mail to a distribution list, log an event, run a command or script, or generate reports. Set a hard quota to prevent users from exceeding a storage limit, or simply monitor storage on a volume or folder. Automatically generate quotas. You can configure File Server Resource Manager to apply a specific quota to all existing subfolders and any new subfolders that are created in a volume or folder. For example, you can automatically generate standard quotas for roaming users or new users in your organization. Manage file screens Create, update, and obtain information about file screens, which control the type of files that users can save. Define file groups that specify file extensions to include in or exclude from custom filtering. Actively prevent users from saving unauthorized files, or simply record when users save those file types. Create screening exception rules for specific folders. When users attempt to save unauthorized files, trigger e-mail or other notifications. Use quota and file screening templates Reuse resource management rules across an organization by applying standard storage limits or file screens to new volumes or folders. Use or modify built-in templates or create new ones to capture your system policies. Manage updates to quotas or file screens from a central location by updating the properties of templates. Run storage reports Choose from a large collection of built-in reports, and set report parameters specific to your environment. Schedule periodic reports to identify trends in disk usage or file screening activity. Generate reports instantly, on demand. Manage remote resources. You can manage storage resources on a local server or on a remote server running File Server Resource Manager. Easily back up and restore settings. File Server Resource Manager configurations are saved in the System Volume Information folder in the server root directory and on any volume where quotas or file screens are applied. To back up and restore File Server Resource Manager configurations, you can use a backup tool such as Windows Server Backup. Is File Server Resource Manager available in all editions of Windows Server 2008?File Server Resource Manager is available in all editions of Windows Server 2008, and is a service included in the Server Core installation option of Windows Server 2008.

Windows Server BackupThe Windows Server Backup feature provides a basic backup and recovery solution for computers running the Windows Server® 2008 operating system. Windows Server Backup introduces new backup and recovery technology and replaces the previous Windows Backup (Ntbackup.exe) feature that was available with earlier versions of the Windows operating system. What does Windows Server Backup do?The Windows Server Backup feature in Windows Server 2008 consists of a Microsoft Management Console (MMC) snap-in and command-line tools that provide a complete solution for your day-to-day backup and recovery needs. You can use four wizards to guide you through running backups and recoveries. You can use Windows Server Backup to back up a full server (all volumes), selected volumes, or the system state. You can recover volumes, folders, files, certain applications, and the system state. And, in case of disasters like hard disk failures, you can perform a system recovery, which will restore your complete system onto the new hard disk, by using a full server backup and the Windows Recovery Environment. You can use Windows Server Backup to create and manage backups for the local computer or a remote computer. You can also schedule backups to run automatically and you can perform one-time backups to augment the scheduled backups. Who will be interested in this feature?Windows Server Backup is intended for use by everyone who needs a basic backup solution—from small business owners to IT professionals in large enterprises. However, the design makes it especially well-suited for smaller organizations or individuals who are not IT professionals. Are there any special considerations?You must be a member of the Administrators group or Backup Operators group to use Windows Server Backup. In Windows Server 2008, the firewall has been enabled by default. If you are managing the backups of another computer using the Windows Server Backup snap-in, your connectivity to the remote computer may be affected and can be resolved by changes in the firewall rules. While working on the local computer, you are not affected. Also, if you are a current user of the previous backup feature (Ntbackup.exe) that shipped in earlier versions of Windows, and plan to switch to the new Windows Server Backup, you might be affected by the following issues and changes: Settings for creating backups will not be upgraded when you upgrade to Windows Server 2008. You will need to reconfigure settings. You will need a separate, dedicated disk for running scheduled backups. Only NTFS-formatted volumes on a locally attached disk can be backed up. You can no longer back up to tape. (However, support of tape storage drivers is still included in Windows Server 2008.) Windows Server Backup supports backing up to external and internal disks, DVDs, and shared folders. You cannot recover backups that you created with Ntbackup.exe by using Windows Server Backup. However, a version of Ntbackup.exe is available as a download to Windows Server 2008 for users who want to recover data from backups created using Ntbackup.exe. The downloadable version of Ntbackup.exe is only for recovering backups for older versions of Windows and cannot be used to create new backups in Windows Server 2008. To download Ntbackup.exe, see http://go.microsoft.com/fwlink/?LinkId=82917. What new functionality does Windows Server Backup provide?Windows Server Backup includes the following improvements: Faster backup technology. Windows Server Backup uses Volume Shadow Copy Service (VSS) and block-level backup technology to back up and recover your operating system, files and folders, and volumes. After the first full backup is created, you can configure Windows Server Backup to automatically run incremental backups by saving only the data that has changed since the last backup. Even if you choose to always perform full backups, your backup will take less time than it did in earlier versions of Windows. Simplified restoration. You can restore items by choosing a backup and then selecting specific items from that backup to restore. You can recover specific files from a folder or all the contents of a folder. In addition, previously, you needed to manually restore from multiple backups if the item was stored on an incremental backup. But this is no longer true—you can now choose the date of the backup version for the item you want to restore. Simplified recovery of your operating system. Windows Server Backup works with new Windows recovery tools to make it easier for you to recover your operating system. You can recover to the same server—or if the hardware fails, you can recover to a separate server that has similar hardware and no operating system. Ability to recover applications. Windows Server Backup uses VSS functionality that is built into applications like Microsoft® SQL Server® to protect application data. Improved scheduling. Windows Server Backup includes a wizard that guides you through the process of creating daily backups. System volumes are automatically included in all scheduled backups so that you are protected against disasters. Offsite removal of backups for disaster protection. You can save backups to multiple disks in a rotation, which enables you to move disks from an offsite location. You can add each disk as a scheduled backup location and, if the first disk is moved offsite, Windows Server Backup will automatically save backups to the next disk in the rotation. Remote administration. Windows Server Backup uses an MMC snap-in to give you a familiar and consistent experience for managing your backups. After you install the snap-in, you can access this tool through Server Manager or by adding the snap-in to a new or existing MMC console. Then, you can manage backups on other servers by clicking the Action menu in the snap-in, and then clicking Connect to Another Computer. Automatic disk usage management. After you configure a disk for a scheduled backup, Windows Server Backup automatically manages the disk usage—you do not need to be concerned about running out of disk space after repeated backups. Windows Server Backup will automatically reuse the space of older backups when creating new backups. The management tool displays the backups that are available and the disk usage information. This can help you plan for provisioning additional storage to meet your recovery time objectives. Extensive command-line support. Windows Server Backup includes the Wbadmin command and documentation, which enable you to perform all of the same tasks at the command line that you can perform by using the snap-in. For more information, see the Command Reference (http://go.microsoft.com/fwlink/?LinkId=93131). You can also automate backup activities through scripting. In addition, Windows Server 2008 contains a collection of Windows PowerShell™ commands (cmdlets) for Windows Server Backup that you can use to write scripts to perform backups. For more information, see http://go.microsoft.com/fwlink/?LinkId=93317. Support for optical media drives and removable media. You can manually back up volumes directly to optical media drives, such as DVD drives, and also to removable media. This offers a solution if you want to create backups that can easily be moved offsite on a one-time basis. This version of Windows Server Backup retains support for manual backups to shared folders and hard disks. Is Windows Server Backup available in all editions of Windows Server 2008?Windows Server Backup is available in all editions of Windows Server 2008 (both 32-bit and 64-bit versions). However, the Windows Server Backup snap-in is not available for the Server Core installation option of Windows Server 2008. To run backups for computers with a Server Core installation, you need to either use the command line or manage backups remotely from another computer. In addition, Windows PowerShell is not available for the Server Core installation option, so the cmdlets for Windows Server Backup are also not available on this type of installation. Does it behave differently in some editions?Windows Server Backup behaves the same in all editions of Windows Server 2008. Is it available in both 32-bit and 64-bit versions?Windows Server Backup is available in both 32-bit and 64-bit versions of Windows Server 2008.

Services for Network File SystemServices for Network File System (NFS) provides a file sharing solution for enterprises that have a mixed Windows® and UNIX environment. With Services for NFS, you can transfer files between computers running the Windows Server® 2008 operating system and the UNIX operating system using the NFS protocol. Who will be interested in this feature?Services for NFS is intended for use by IT professionals who need a way to share data to users in heterogeneous or homogeneous environments. Its scalable design makes Services for NFS appropriate for large enterprises. Are there any special considerations?You must be a member of the Administrators group to administer Services for NFS. What functionality has been removed?To streamline and simplify Services for NFS, the following features were removed for Windows Server 2008: Gateway for NFS Server for Personal Computer Network File System (PCNFS) All PCNFS components of Client for NFS User Name Mapping (server role)
Active Directory Lookup. Identity management for the UNIX Active Directory schema extension includes UNIX user identifier (UID) and group identifier (GID) fields. This enables Server for NFS and Client for NFS to look up Windows-to-UNIX user account mappings directly from Active Directory Domain Services (AD DS). Identity management for UNIX simplifies Windows-to-UNIX user account mapping management in AD DS. 64-bit version support. You can install Services for NFS components on all Windows Server 2008 operating systems, including 64-bit versions. Enhanced server performance. Services for NFS includes a file filter driver, which significantly reduces common file access latencies. UNIX special device support. Services for NFS supports UNIX special devices (the mknod function). Enhanced UNIX support. Services for NFS supports the following versions of UNIX: Sun Microsystems Solaris version 9, Red Hat Linux version 9, IBM AIX version 5L 5.2, and Hewlett Packard HP-UX version 11i.

Storage Manager for SANsIntroduced with the Windows Server® 2003 R2 operating system, Storage Manager for SANs is an optional feature in Windows Server® 2008. It helps you create and manage logical unit numbers (LUNs) on Fibre Channel and Internet SCSI (iSCSI) disk drive subsystems that support Virtual Disk Service (VDS) in your storage area network (SAN). What does Storage Manager for SANs do?With the Microsoft Management Console (MMC) snap-in for Storage Manager for SANs, you can perform the following tasks in your SAN: Manage storage allocation in the SAN by creating LUNs on Fibre Channel and iSCSI disk drive storage subsystems. Manage the connections between computers in your SAN that are running Windows Server 2008 and the storage subsystems. Create volumes on LUNs, and assign LUNs to servers or clusters in your SAN. Monitor the status of LUNs and disk drives in your storage subsystems.
Who will be interested in this feature?The following groups will especially benefit from using Storage Manager for SANs: IT administrators who want to easily manage storage allocation on disk drive storage subsystems in their SAN that are compatible with VDS. IT administrators who manage iSCSI storage subsystems and are seeking a single tool to create, configure, and manage iSCSI targets.
Are there any special considerations?The following are some software and hardware prerequisites to use Storage Manager for SANs: You must belong to the Administrators group of the computer running Storage Manager for SANs. To create and manage LUNs with Storage Manager for SANs, your disk drive storage subsystem must support VDS 1.1, and the VDS hardware provider must be installed on the computer that is running Windows Server 2008. Storage Manager for SANs works with VDS-compatible subsystems that support either the Fibre Channel or iSCSI network storage protocol. If you plan to use Storage Manager for SANs to manage storage resources on a remote server, that server must be running Windows Server 2008 with the appropriate VDS hardware provider. To provide LUN access to a server cluster using Storage Manager for SANs, Failover Clustering must be installed on each server running Windows Server 2008 that will be part of the cluster.
What functionality does this feature provide?You can use Storage Manager for SANs in Windows Server 2008 to perform the following tasks: View details of supported storage subsystems. Display the status and technical details of Fibre Channel and iSCSI storage subsystems that are automatically discovered. Use information about available capacity and supported LUN types to plan storage allocation in your SAN. Create and manage LUNs on the storage subsystems. Create a new LUN on a storage subsystem and easily assign the LUN to a server. Display all LUNs on the storage subsystems, including details such as online status, size, and type. Assign a LUN to a cluster of servers running Windows Server 2008 to make the storage highly available. Configure server connections on the SAN. Enable which host bus adaptor (HBA) ports or iSCSI initiator adaptors on servers in your SAN will have access to LUNs that are created on the storage subsystems. Create and manage iSCSI targets. Create and configure security settings for iSCSI storage subsystems and start logon sessions with targets on the subsystems. List physical drives on the storage subsystems. Display the status of disk drives on the storage subsystems. Make a light blink on a drive to assist in maintaining your storage system hardware.
