I need to test a scenario where a file contains a BACKUP_REPARSE_DATA stream. We have a customer that is unable to perform a BackupWrite() to this stream; they get an ERROR_ACCESS_DENIED. I want to try performing a normal ReadFile() when I encounter a BACKUP_REPARSE_DATA and do some in-house testing before I build a patch. What's the easiest way to create a test file with this stream? Thanks for any help.
