This procedure describes a backup process for Doors.NET databases using Microsoft SQL Studio Manager 2019, however, the procedure is almost identical to other versions of SQL Studio Manager.
Note: These instructions specifically cover a Disc backup; Tape backup is not covered.
Note: Microsoft does not provide a downgrade path for SQL databases. This means you cannot, for example, use SQL 2016 or 2019 files on a SQL 2012 database engine. You can, however use SQL 2012 database files on any other newer version of SQL Server.
