Summary: The Volume Shadow Copy service is a built-in Windows technology that provides backup infrastructure for Microsoft Windows OS and Microsoft Servers. However, it sometimes runs into VSS errors preventing a user from creating backups or performing system restore. Use methods like enabling VSS or repairing damaged system files to resolve this issue.
Windows OS has numerous advanced features that allow automation of certain processes. One such is the Volume Snapshot Service or Volume Shadow Copy or VSS, a built-in tool that allows users to manually or automatically create file backups. This service uses snapshots of computer files or volumes to maintain backups.
However, sometimes, while taking backups or performing a system restore, users unexpectedly get a strange message stating that the Volume Shadow Copy Service is not working or has failed. In some instances, the error message is accompanied by an error code like 0x807800A1, 0x800423F4, 0x81000202, or 0x80042302.
Users even encounter this message while using the backup and restore feature (Windows 7), ultimately preventing them from creating the data backups. To help you out, we have compiled this exhaustive guide for you to fix the volume shadow copy service (VSS) is not working error your Windows 10/11 PC. Let?s read further.
What is Volume Shadow Copy Service (VSS)?
Volume Shadow Copy Service, or Volume Snapshot Service, or simply Shadow Copy, is a built-in Windows feature that provides backup infrastructure for Microsoft Windows OS and Microsoft Servers. It creates consistent, uncorrupted, or clean point-in-time copies of data known as ?shadow copies?.
The VSS or Volume Shadow Copy service has native support for creating consistent copies regardless of the technology used for creating them. It works in tandem with third-party business applications, file system services, fast recovery solutions, and more to produce high-quality and consistent shadow copies without errors. However, VSS requires NTFS to be used on a volume.
Why do Volume Shadow Copy Errors Occur?
There are no specific reasons behind users getting Volume shadow copy errors on their Windows computers. In general, VSS errors are a result of disabled volume snapshot service, dependent components not working, damaged or broken system files, etc.
Methods to Fix Volume Shadow Copy Errors on Windows Computers
Volume Shadow Copy service-related errors are uncommon; hence, a common user might get perplexed. However, there are fixes available that can be employed to resolve VSS errors in a matter of a few clicks. Let?s walk you through them one by one.
