Most often, the name server includes the name of it’s main functions:

• File server, print server, mail server, news server; Web-server;
• Database server;
• Fax-server, etc.

Servers can also be classified according to the signs indicating the nature of it’s use:

• Dedicated server;
• Listen server.

Dedicated server on the LAN are intended solely to provide their resources in common use, and not to work directly on it, so it can properly function without a monitor and keyboard. It usually has a high capacity and reliability of equipment and software used.

The operating system is a dedicated server which is most often used:

• Microsoft Windows 2003 Server;
• Microsoft Windows 2008 Server;
• Microsoft Windows 2003 R2 Server;
• Microsoft Windows 2008 R2 Server;
• Linux, FreeBSD, Sun Solaris and other varieties of Unix;

Unselected server combines the functions of server and workstation. In other words, it’s a workstation, some of the resources which are dedicated to sharing access to the network. On the workstation (no dedicated server) operating system may be, for example:

• Microsoft Windows 98/ME;
• Microsoft Windows XP Professional;
• Microsoft Windows 2000 Workstation.

• Linux.

In ad-hoc local networks, computers are together in working groups (Workgroups), where they function as a workstation or a listen server, providing a portion of their resources for use by its working group. Peer networks are easier to administer, but do not provide a high degree of data protection.

Local network with a dedicated server, in contrast, have increased reliability and security of information stored on the server.

In order to enable VSS based backups of Hyper-V VMs using Windows Server Backup you must add the following registry keys to register the Hyper-V VSS Writer with Windows Server Backup,  Note that the WindowsServerBackup key is not created when installing. This key must be created manually.

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT

\CurrentVersion\WindowsServerBackup\Application Support\{66841CD4-6DED-4F4B-8F17-FD23F8DDC3DE}

Once you have the keys listed above created, you will need to create a String Value with the following.

Name: Application Identifier
Type: REG_SZ
Value: Hyper-V

When complete, the keys should resemble the following:

When backing up virtual machines, you must select all volumes where VM related files are present. Windows Server Backup only supports volume based backups.

For example, if you are using the default location for storing virtual machine configuration (C:\ProgramData\Microsoft\Windows\Hyper-V\Virtual Machines) yet the VHD is stored on another volume, you must select both volumes in the backup.

When initiating recovery, select “Application Restore” and choose Hyper-V. You must use this method otherwise you will not be allowed to replace files for running VMs. As part of the restore, existing VMs will be turned off and deleted. The VMs that you restore will be registered with Hyper-V Hosting.
