I recently installed SQL Server 2017 Express (Version 14.0.1000.169) and Management Studio 2017 (Release 17.8.1, Build number 14.0.17277.0). At present, all the software is on the system drive (C:) as are folders named DATA.
I would like to know how I can backup all the work on an external drive so that if I make a mistake (being a University student) I can go back to the version that contains the 'good data'. I imagine this would involve the data kept by the server as well as the actual database files.
Kind regards,
Ivo Martinek
