FIX: SQL DMO's SQLBackup Method Fails with Error Message 3206 (308789)

SYMPTOMS

A call to the SQLBackup method in SQL Distributed Management Objects (SQL-DMO) may return this error message:

0x80040c86

If you use SQL Profiler to trace the calls, and you then execute the captured syntax through Query Analyzer, these error messages occur:

Server: Msg 3206, Level 16, State 1, Line 1
No entry in sysdevices for backup device 'disk='c:\pubs.bak''. Update sysdevices and rerun statement.

Server: Msg 3013, Level 16, State 1, Line 1
BACKUP DATABASE is terminating abnormally.

CAUSE

The SQL-DMO object incorrectly places brackets [] around the backup_device parameter in the BACKUP command. SQL-DMO should only add the brackets when the device is a logical (named) device that uses an identifier, and not add the brackets when the device is a physical device. When SQL-DMO adds the brackets, the syntax of the command is incorrect.
