Each writer is controlled by a Windows Service. This list is for reference use only. VSS allows backups of in-use, locked, or open files without interrupting whatever process or user is currently accessing those files.
Writers that display as In-Progress or Waiting for Completion are currently in use by some backup process. A list of currently-available Writers can be accessed via the command prompt on any Windows computer. I can walk you through this process!
Run command prompt as an Administrator and run the command: A list of currently available writers can be seen via the command line on any Windows machine. If a service cannot be restarted, a reboot of the machine is required. This is especially useful for databases, as it allows backups to be performed while the database is active without requiring downtime.
If a Writer is listed as In-Progress or Waiting for Completion when no backups are running, the Writer may be "stuck". This command will list all of the Writers currently available on the machine and display the state of each.
Ideally, all Writers should be Stable when no backups are in progress. A reference list of VSS Writers and their controlling services can be found below. Restarting the service that controls the writer will reset the writer and, in most cases, bring it back to a stable state.
Writers in the Failed or Unstable states have encountered a problem, and may need to be reset. Yes please, show me how! Writers that are currently In-Progress are being used for a backup. The sections below are collapsed.
Stuck Writers must be reset like a Failed or Unstable Writer. Writers in the Failed or Unstable states have encountered a problem, and must be reset to bring the Writer back to a Stable state.
It is not comprehensive. If no backups are running, the writer may be stuck, and can be reset like Failed or Unstable writers.
Each backup type will have its own set of Writers, and each Writer is controlled by a Windows Service. This is especially useful for databases, as it means backups can be taken while the database is active, without requiring downtime. When the backup is finished, the Writer will revert to the Stable state.
A system may have active Writers that are not in this list. A writer in the Stable state is ready and waiting to take a backup. For System State, some Writers that do appear in the list may not be required for the backup to complete.
It is also important to note that restarting some services can cause downtime for the application that is related to the service. VSS allows backups to be taken of in-use, locked, or inaccessible files without interrupting whatever process or user is currently accessing those files.
A system will only have Writers that correspond to Windows components that are installed on the system. Open a command prompt as an Administrator and run the command: It is important to note that not all services that control VSS Writers can be restarted.
This usually brings the Writer back to a stable state. It is important to note that not all controlling services can be restarted. If a service cannot be restarted, a reboot of the machine is required.Step 3: Find the VSS writer's associated Service Display Name in the table below and restart the service.
Microsoft SharePoint Foundation Service Pack 1 (SP1) was recently released through Microsoft Update. On a default installation, Windows SBS Standard administrators should be able to see it in the SBS Console and would need to approve it for installation before it is offered for installation on the server.
VSS Writer Failed: Re-registering VSS Writers on Windows Server Most backup solutions for Windows use Volume Shadow Copy Service (VSS) to create backup copies of the application or service data.
In some cases, the VSS service or one of its writers start to work incorrectly which results in failures during the backup.
Find the VSS writer's associated Service Display Name in the table below and restart the service (helpful table below). Figure 2 Open ultimedescente.com (Start > Run > ultimedescente.com), and stop any VSS related service that are running.

In most cases, the Windows Service that controls a VSS Writer can be restarted.
This usually brings the Writer back to a stable state. For example, the Microsoft Exchange Writer is controlled by the Microsoft Exchange Information Store (MEIS) service.Download
