Hi,
Denodo Server will not get into Single User mode during the export process. The line “ENTER SINGLE USER MODE;” that you see on the exported VQL file is to instruct the Server to enter into Single User mode during the import process.
You can refer to the [Export and Import Script](https://community.denodo.com/docs/html/browse/6.0/vdp/administration/cluster_architectures_server_backup/using_the_import_export_scripts_for_backup_and_or_replication/export_script) sections on the Virtual DataPort Administration Guide to get more details.
Hope this helps.
