Windows Home Server (code-named Quattro [4] ) is a home server operating system from Microsoft. It was announced on 7 January 2007 at the Consumer Electronics Show by Bill Gates, [5] released to manufacturing on 16 July 2007 [6] and officially released on 4 November 2007. [7]

Contents

Windows Home Server was based on Windows Server 2003 R2 and was intended to be a solution for homes with multiple connected PCs to offer file sharing, automated backups, print server, and remote access. It is paired with the Windows Home Server Console—client software accessed from another computer on the network to provide a graphical management interface.

Power Pack 1 for Windows Home Server was released on 20 July 2008. [8] Power Pack 2 was released on 24 March 2009 and Power Pack 3 was released on 24 November 2009. [1]

Windows Home Server 2011, the next version of this operating system, was released on 6 April 2011. [9] Microsoft confirmed Windows Home Server 2011 to be last release in the Windows Home Server product line. [10]

Windows Home Server was the brainchild of Charlie Kindel who was the General Manager for the product from 2005 through 2009. [11] [12]

Microsoft has ended support for Windows Home Server on 8 January 2013. [13]

Features

Technology

Home Server Console

The Windows Home Server Console

The configuration interface was designed to be user-friendly enough that it could be set up without prior knowledge of server administration. The configuration interface, called the Home Server Console, was delivered as a Remote Desktop Protocol application to remote PCs while the application ran on the server itself, the GUI was rendered on the remote system. The Home Server Console client application could be accessed from any Windows PC. The server itself required no video card or peripherals; it was designed to require only an Ethernet card and at least one Windows XP, Windows Vista or Windows 7 computer.

Drive Extender

Windows Home Server Drive Extender was a file-based replication system that provided three key capabilities: [21]

With Drive Extender, users could add larger capacity hard disk drives and then could offline lesser capacity drives to upgrade capacity online. For example, if the user was reaching capacity of the share with five terabytes of the six-terabyte capacity used with six one-terabyte drives then the user could offline one of the one-terabyte drives and physically replace it with a two-terabyte drive. The WHS automatically equalizes the redistribution of used space across all available drives on a regular basis. The offline process would compress the used data across the minimum amount of drives allowing for the removal of one of the lesser capacity drives. Once replaced with a drive of higher capacity the system will automatically redistribute used capacity among the pool to ensure space capacity on each drive.

Users (specifically those who configure a family's home server) dealt with storage at two levels: Shared Folders and Disks. The only concepts relevant regarding disks was whether they had been "added" to the home server's storage pool or not and whether the disk appeared healthy to the system or not. This was in contrast with Windows' Logical Disk Manager which requires a greater degree of technical understanding in order to correctly configure a RAID array.

Shared Folders had a name, a description, permissions, and a flag indicating whether duplication (redundancy) was on or off for that folder.

If duplication was on for a Shared Folder (which was the default on multi-disk Home Server systems and not applicable to single disk systems) then the files in that Shared Folder were duplicated and the effective storage capacity was halved. However, in situations where a user may not have wanted data duplicated (e.g. TV shows that had been archived to a Windows Home Server from a system running Windows Media Center), Drive Extender provided the capability to not duplicate such files if the server was short on capacity or manually mark a complete content store as not for duplication. [22]

A known limitation of Drive Extender was that it in some cases changed timestamp of directories and files when data was moved around between disks. According to Microsoft this was expected behavior. This caused unexpected behavior when using clients that sort media based on date. Examples are XBMC, MediaPortal, and Squeezebox Server. The aforementioned programs worked fine with WHS; however, files may have appeared out of order due to this caveat.

Cancellation

On 23 November 2010, Microsoft announced that Drive Extender would be removed from Windows Home Server 2011. [2] This led to public outcry in the announcement's comments section. Criticism of Drive Extender's removal mainly related to it being seen as a core feature of Windows Home Server and a key reason for adoption. [23] As a replacement for Drive Extender, Microsoft stated that OEMs would use RAID on their Windows Home Server products.

Computer Backup and Restore

Windows Home Server Computer Backup automatically backs up all of the computers in a home to the server using an image-based system that ensures point-in-time-based restoration of either entire PCs or specific files and folders. [24] Complete bare-metal restores are initiated through a restore bootable CD, file based restores are initiated through the WHS client software which allows the users to open a backup and "drag and drop" files from it. This technology uses Volume Shadow Services (VSS) technology on the client computer to take an image based backup of a running computer. Because the backup operates on data at the cluster level, single instancing can be performed to minimize the amount of data that travels over the network and that will ultimately be stored on the home server. This single instancing gives the server the ability to store only one instance of data, no matter if the data originated from another computer, another file, or even data within the same file.

Computer backup images are not duplicated on the server, so if a server hard drive fails, backups could be lost. The "Server Backup" feature added in Power Pack 1 does not include duplication of backup images.

Remote File Access

The system also offers an SSL secured web browser based interface over the Internet to the shared file stores. [25] The release version offers access to the web interface via a free Windows Live-provided URL, which uses Dynamic DNS. The web interface also allows the uploading to and downloading of files from the content stores. [20] However, there is a limit of 2 GB for a single batch of upload. [19]

Remote Desktop Services

The system also supports Terminal Services Gateway, allowing remote control of the desktop of any Windows computer on the home network. [19] [25] Currently supported systems are those which would normally support Remote Desktop: Windows XP Professional, Tablet and Media Center editions, Windows Vista Business, Enterprise and Ultimate editions and Windows 7 Professional, Enterprise and Ultimate editions. The web interface also supports embedding the Remote Desktop ActiveX control, to provide remote access to home computers from within the web interface directly. Remote sessions can also connect to the Home Server console to configure the server over the internet. [19]

Add-Ins

Windows Home Server allows for developers to publish community and commercial add-ins designed to enhance the Windows Home Server with added functionality. As of January 2010, nearly 100 of these add-ins have been developed for WHS, including applications for antivirus & security, backups, disk management, automation, media, network/power management, remote access, BitTorrent and more. The Windows Home Server SDK (Software Development Kit) provides developers with a set of APIs and tools to use when developing for and extending Windows Home Server.

Windows Home Server features integration with Windows XP (SP2 or newer), Windows Vista, and Windows 7 (after the release of Power Pack 3) through a software installation, either from a client CD or via a network share. [27] The connector software may also be installed by accessing yourserver:55000 through a web browser, where a link is provided to download the connector software and to install troubleshooting tools. Files stored on Windows Home Server are also available through a Windows share, opening compatibility to a wide variety of operating systems. Also, the Administration console is available via Remote Desktop, allowing administration from unsupported platforms.

Windows Home Server does not support Microsoft Security Essentials. [28]

64-bit Windows client support was introduced in Power Pack 1, though the Restore Wizard on the Windows Home Server Restore CD is unable to restore clients running 64-bit operating systems, due to the fact that the Restore CD does not support 64-bit drivers. [8] Windows XP Professional x64 isn't officially supported. However, unofficial workarounds allow Connector software to work on XP x64. [29]

Integration of the file sharing service as a location for Mac OS X's Time Machine was apparently being considered, [30] but upon Mac OS X Leopard's release, Apple had removed the ability to use the SMB file sharing protocol for Time Machine backups. [31] One WHS provider, HP, provides their own plug-in with their home server line capable of Time Machine backup to a home server. [32]

Windows Home Server has not officially supported Domain Controller capability and cannot readily join a Windows Server domain. Wireless networking is supported.

Dedicated devices will have the operating system pre-installed and may be supplied with a server recovery disk which reloads the OS over a network connection. This is utilized on the HP MediaSmart Server, [33] and the Fujitsu Siemens Scaleo Home Server.

Resolved issues

File corruption

The first release of Windows Home Server, RTM (release to manufacturing), suffered from a file corruption flaw whereby files saved directly to or edited on shares on a WHS device could become corrupted. [34] Only the files that had NTFS Alternate Data Streams were susceptible to the flaw. [35] The flaw led to data corruption only when the server was under heavy load at the time when the file (with ADS) was being saved onto a share. [36]

Backups of client PCs made by Windows Home Server were not susceptible to the flaw. [36]

Even though the issue was first acknowledged in October 2007, [37] Microsoft formally warned users of the seriousness of the flaw on 20 December 2007. Microsoft then issued a list of applications, including Windows Live Photo Gallery, Microsoft OneNote, Microsoft Outlook and SyncToy 2.0, which might have triggered the flaw if they were used to edit the files on a WHS share directly. [34]

This issue was fixed by Power Pack 1, released on 21 July 2008. [8]

No native backup

Windows Home Server RTM did not include a mechanism for backing up the server. Power Pack 1 added the ability to back up files stored on the Shared Folders, to an external drive. [8] Users can also subscribe to 3rd-party online services, for a fee. However, there remains no way to back up the installed server operating system. Backing-up of the client backup database is available either manually using the instructions provided by Microsoft on page 24 of this document or can be done using the WHS BDBB add-in written by Alex Kuretz and available from this website.

Pricing

While some hardware manufacturers have developed dedicated boxes, [38] Microsoft has also released Windows Home Server under the OEM/System Builder license. In November 2008, Microsoft lowered the price of the WHS System Builder SKU to US$100. [39]

Users can also choose to use an existing PC or build their own systems, which would include the use of WHS System Builder.

As of 23 March 2009, Microsoft has also made Windows Home Server available to MSDN and Microsoft Technet subscribers. [40]

Some computer systems are available only with a bundled Windows Home Server license. As is the case with other versions of Windows it is possible to request a refund of the license fees paid for Windows Home Server. [41]

In information technology, a backup, or data backup is a copy of computer data taken and stored elsewhere so that it may be used to restore the original after a data loss event. The verb form, referring to the process of doing so, is "back up", whereas the noun and adjective form is "backup". Backups can be used to recover data after its loss from data deletion or corruption, or to recover data from an earlier time.  Backups provide a simple form of disaster recovery; however not all backup systems are able to reconstitute a computer system or other complex configuration such as a computer cluster, active directory server, or database server.

In computing, a shared resource, or network share, is a computer resource made available from one host to other hosts on a computer network. It is a device or piece of information on a computer that can be remotely accessed from another computer transparently as if it were a resource in the local machine. Network sharing is made possible by inter-process communication over the network.

Single-instance storage (SIS) is a system's ability to take multiple copies of content and replace them by a single shared copy. It is a means to eliminate data duplication and to increase efficiency. SIS is frequently implemented in file systems, e-mail server software, data backup, and other storage-related computer software. Single-instance storage is a simple variant of data deduplication. While data deduplication may work at a segment or sub-block level, single-instance storage works at the whole-file level and eliminates redundant copies of entire files or e-mail messages.

NTBackup is the first built-in backup utility of the Windows NT family. It was introduced with Windows NT 3.51. NTBackup comprises a GUI (wizard-style) and a command-line utility to create, customize, and manage backups. It takes advantage of Shadow Copy and Task Scheduler. NTBackup stores backups in the BKF file format on external sources, e.g., floppy disks, hard drives, tape drives, and Zip drives. When used with tape drives, NTBackup uses the Microsoft Tape Format (MTF), which is also used by BackupAssist, Backup Exec, and Veeam Backup & Replication and is compatible with BKF.
