If the path does not exist, Sql Server will attempt to create it. Folders are created by the Sql Instance, and checks will be made for write permissions.<br />

If the same name is used repeatedly, SQL Server will add backups to the same file at an incrementing position.<br />
SQL Server needs permissions to write to the specified location. Path names are based on the SQL Server (C:\ is the C drive on the SQL Server, not the machine running the script).<br />
Passing in NUL as the FilePath will backup to the NUL: device<br></p>
