Symptoms

Consider the following scenario. On a Windows Server 2008-based computer or on a Windows Vista-based computer, you use an application that has the backup permission enabled. The application also uses the BackupRead API function to read stream data from an encrypted file. In this scenario, the application cannot read the stream data from the encrypted file. Additionally, the GetLastError API function returns the ERROR_ACCESS_DENIED error value.

Cause

This problem occurs because the FSCTL_TXFS_READ_BACKUP_INFORMATION control code requires explicit read access to the encrypted file. However, the backup permission does not grant it. Therefore, the FSCTL_TXFS_READ_BACKUP_INFORMATION control code returns the STATUS_ACCESS_DENIED error value, and the BackupRead API function fails.

Resolution
