Hi，Manjunatha Reddy

The issue should be related to the system environment.

Here are several possible reasons:

1. Insufficient disk space, ensure the backup directory has enough space.
2. Insufficient permissions, unable to properly access the backup files, or no operational authority over the backup path.
3. The backup file directory cannot be the root directory of the disk.

Did you execute the command through the SSMS UI interface? Make sure the target file name is correct.

Best Regards,

You may want to look in Services to ensure that SQL VSS Writer is started. The guid is a virtual backup and in order for Virtual Backups to work, VSS Writer needs to be started.
