Issue: How to fix Event ID 8193: Volume Shadow Copy Service error in Windows?

Hello. I keep seeing the Event ID 8193: Volume Shadow Copy Service error in Event Viewer on Windows. How do I fix this?

Solved Answer

Event ID 8193 is a common error that occurs in Windows' Volume Shadow Copy Service (VSS).^[1] The VSS is a Windows feature that allows the creation of snapshots or shadow copies of files and folders on the system while they are in use. These shadow copies can be used to recover data in the event of accidental deletion or other types of data loss.

The Volume Shadow Copy Service allows backups and restore points to be created without shutting down the system or requiring users to close applications that may be using the files being backed up. This feature is especially beneficial to businesses and organizations that must ensure the availability and integrity of data on their systems.

When the VSS is unable to complete a backup or restore operation due to permissions or other system settings issues, the Event ID 8193 error occurs. This can have a variety of consequences, including data loss or the inability to restore data from a backup. It may also impair system performance or stability.

Checking system permissions, ensuring that the VSS service is running, and making changes to system settings that may be interfering with the VSS are all possible solutions to the Event ID 8193 error. It is important to note that changing the system registry or other system settings can be risky.
