If you delete the backup device and recreate it, backups can then be done in Recorder 6 running with Windows 7. To do this you will need to have installed SQL Server tools, e.g. Management Studio Express. There is a download link for them in http://forums.nbn.org.uk/viewtopic.php?pid=8317#p8317 . Once you have installed Management Studio Express it will be available on the Start menu.

On my Windows 7 PC, I click on the Start button (bottom left) and select All Programs, then Microsoft SQL Server 2005, then right click SQL Server Management Studio and select Run as administrator. You should then see a Connect to Server box where clicking Connect should take you into Management Studio. Once in it, you should be able to see NBNData if you click on the + beside Databases in the hierarchy on the left. If so, click on the + beside Server Objects then the + beside Backup Devices. Right click NBNData_Backup and select ‘Delete’. When it has been deleted, recreate it by right clicking Backup Devices and selecting ‘New Backup Device’. For Recorder 6 the backup device must be called NBNData_Backup and you will need to specify where it is to be stored. The Backup folder in your Microsoft SQL Server folder is probably the most appropriate location, e.g. C:\Program Files (x86)\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQL\Backup.
