If for any reason you are prompted to upload your backup file, below are the expected type of files and guide on how to get it.
To create a .BAK backup file for Microsoft Dynamics Navision, you will first need to open your Microsoft SQL Server Management Studio application.
Log into the instance where the database is located.
Within the Object Explorer, expand the 'Databases' folder.
Right click on the database you would like to create a backup file for. Click 'Tasks' and select 'Backup'. This will prompt open the backup database dialogue box.
In the General Tab, under 'Source', make sure that the Backup type is 'Full' and check mark the 'Copy-only backup'. This will create an exact copy of the database.
To compress the file, select the Backup Options Tab and under 'Compression', set backup compression by selecting, 'Compress backup'. This will reduce the space required to create the backup and reduce the time required to upload to DataShare.
Once the options have been selected, click on 'OK' to create the backup file.
