To diagnose the Volume Shadow Copy service writer problem, run the vssadmin command immediately after the backup failure: Run. Type vssadmin list writers. This command lists the Volume Shadow Copy service writers and the current state of each writer.

Fixes a problem that logs an "Access is denied" error when you perform a backup or run the "vssadmin list writers" command on a cluster node in Windows Server 2012 or Windows Server 2012 R2.

When you use a backup application that uses VSS to back up files, you might notice an unexpected increase in disk space usage. This may occur in a corner case. When you examine the disk, you find that it is filled with undeleted snapshot files.

When you run the vssadmin list writers command in Windows Server 2008 R2, no VSS writers are listed. Additionally, the following events are logged in the Application log: Volume Shadow Copy Service error: A critical component required by the Volume Shadow Copy service is not registered.

Change the allocation by using the Vssadmin command, syntax: vssadmin resize shadowstorage /On=C: /For=C: /Maxsize=1G (where Maxsize=the amount of disk space you've allocated to System Restore points, you should increase it larger)

To resolve this issue, we have released a hotfix for Windows Server 2012 R2 and Windows Server 2012. This hotfix has a prerequisite. A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article.

You run the Vssadmin list writers command to view the writers that are subscribed to the Volume Shadow Copy Service (VSS). You use Windows Server Backup to try to back up the system. In this scenario, System Writer is missing, and the backup fails.

There are different ways to remove apps and programs, so if you can't find the one you're looking for, you can try another location. Note that some apps and programs are built into Windows and can't be uninstalled. You can try to repair a program first, if it's just not running correctly.

To do this, follow these steps: Open an elevated command prompt. To do this, do the following as your appropriate: If you are running Windows 10, Windows 8.1 or Windows 8, first run the inbox Deployment Image Servicing and Management (DISM) tool prior to running the System File Checker.

You may notice the following error log entry when you run BACKUP DATABASE against the snapshots during a Volume Shadow Copy Service (VSS) backup operation. DateTime Backup BACKUP failed to complete the command BACKUP DATABASE DataSnapName. Check the backup application log for detailed messages. DateTime Backup Error: 3041, Severity: 16, State: 1.
