Could you please post the contents of the SQL Backup log file for the backup that failed? The default folder where the logs are stored is C:\\Documents and Settings\\All Users\\Application Data\\Red Gate\\SQL Backup\\Log\\<instance name> on Windows 2003 and older, and C:\\ProgramData\\Red Gate\\SQL Backup\\Log\\<instance name> on Windows Vista and newer.
