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 panel.ini file:
[databaseManagement]
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.
