By default, customers that have the ability to create Microsoft SQL Server databases are also granted the ability to export and import dumps of such databases. It is possible to disable the ability to upload Microsoft SQL Server database dumps to the server. To do so, add the following lines to the
features.uploadMSSQLBackupFile = false
This will hide the Import Dump button in the Plesk interface for all users. Note that this will not affect the users' ability to export Microsoft SQL Server database dumps, or to import and export MySQL database dumps.
