Details Version:. File Name:. Date Published:. File Size:. System Requirements Supported Operating System. If your users need access to the same files and applications, or if centralized backup and file management are important to your organization, you should set up one or more servers as a file server by installing the File and Storage Services role and the appropriate role services. The File and Storage Services role and the Storage Services role service are installed by default, but without any additional role services.

This basic functionality enables you to use Server Manager or Windows PowerShell to manage the storage functionality of your servers.

However, to set up or manage a file server, you should use the Add Roles and Features Wizard in Server Manager or the Install-WindowsFeature Windows PowerShell cmdlet to install additional File and Storage Services role services, such as the role services discussed in this topic.

Administrators can use the File and Storage Services role to set up and manage multiple file servers and their storage capabilities by using Server Manager or Windows PowerShell.

Some of the specific applications include the following:. Storage Spaces - Use to deploy high availability storage that is resilient and scalable by using cost-effective industry-standard disks. Folder Redirection, Offline Files, and Roaming User Profiles - Use to redirect the path of local folders such as the Documents folder or an entire user profile to a network location, while caching the contents locally for increased speed and availability. Work Folders - Use to enable users to store and access work files on personal PCs and devices, in addition to corporate PCs.

Users gain a convenient location to store work files and access them from anywhere. Organizations maintain control over corporate data by storing the files on centrally managed file servers and optionally specifying user device policies such as encryption and lock screen passwords. Work Folders is a new role service in Windows Server R2. Data Deduplication - Use to reduce the disk space requirements of your files, saving money on storage.

Server Manager - Use to remotely manage multiple file servers from a single window. Windows PowerShell Use to automate the management of the majority of administration tasks for file servers. The following table describes some of the major changes in File and Storage Services functionality that is available in Windows Server R2. The following table describes some of the major changes in File and Storage Services functionality that are available in Windows Server For more information about what else is new in File and Storage Services and related technologies, see the following topics.

By using the Data Deduplication role service to reduce the number of duplicate blocks of data in storage, you can store much more data in a given amount of storage capacity than was possible in previous releases that used Single Instance Storage SIS or NTFS file system compression.

General purpose file servers can typically reduce storage capacity utilization by a ratio for example, files that previously used 1 TB would use GB after data deduplication. Servers that host virtualization data such as VHD files often reduce storage capacity utilization by a ratio, which reduces 1 TB of data to 50 GB.

Data deduplication is highly scalable, resource efficient, and nonintrusive. It can run on dozens of large volumes of primary data simultaneously without affecting other workloads on the server. Low impact on the server workloads is maintained by throttling the CPU and memory resources that are consumed. By using data deduplication jobs, you can schedule when data deduplication should run, specify the resources to duplicate, and tune file selection.

Data integrity and recoverability are maximized through checksum and other algorithms by using selective redundancy. When combined with BranchCache, the same optimization techniques are applied to data that is transferred over the WAN to a branch office.

This results in faster file download times and reduced bandwidth consumption. Data deduplication uses variable-size chunking and compression, which together deliver storage optimization ratios of for general file servers and up to for virtualization data.

The replicated folder is often exposed to client computers as an SMB shared folder. For more information about the impact of the migration process on client computers, see Impact of data migration by copying data and shared folders earlier in this document.

For data and shared folder migration, local Administrator permissions are required on the source server and destination server. This section describes permissions that are required to perform the migration on the destination server.

For a stand-alone namespace, the user must be a member of the local Administrators group on the destination server. This section describes permissions that are required to perform the migration on the source server. For a stand-alone namespace, the user must have membership in the local Administrators group on the source server. For DFS Replication, the user who starts the migration must be a member of the Domain Admins group or have delegated permissions to the replication groups and replication members.

This permission is required to remove the source server from replication groups to which it belongs. If the permissions to administer a replication group have been delegated to a particular user through the DFS Management snap-in, that user can use the DFS Management snap-in to perform tasks such as removing the source server from a replication group.

The user must also be a member of the local Administrators group on the source server and the destination server. Migrating Roles and Features in Windows Server. Skip to main content. This browser is no longer supported.

Inventory and transfer operations are significantly faster with more processors and memory. A migration account that is an administrator on the source computers and the orchestrator computer.

This can be a domain or local account except in the case of a computer not joined to the domain, in which case it must be a local user. A migration account that is an administrator on the destination computers and the orchestrator computer. The source and destination computers must have the following firewall rules enabled inbound though you might already have them enabled :. Installing the Storage Migration Service Proxy service on a Windows Server or Windows Server computer automatically opens the necessary firewall ports on that computer.

If the computers belong to an Active Directory Domain Services domain, they should all belong to the same forest. The destination server must also be in the same domain as the source server if you want to transfer the source's domain name to the destination when cutting over. Cutover technically works across domains, but the fully-qualified domain name of the destination will be different from the source. Storage Migration Service can't yet cut over from domain controllers, but can inventory and transfer files from them.
