The backup compression for TDE-enabled databases for SQL Server 2016 and newer versions is available, but at lower transfer size as explained [here](https://techcommunity.microsoft.com/t5/sql-server/backup-compression-for-tde-enabled-databases-important-fixes-in/ba-p/385593).

Database files with other extensions, such as _.dll_, aren't backed-up because the IIS server performs the [file extension request filtering](/iis/configuration/system.webserver/security/requestfiltering/fileextensions).
