SAP MaxDB Loader is a database tool for exporting and importing (unloading and loading) data.
You cannot use data exported with Loader to restore a database because it may represent an inconsistent database state. Exported data is, therefore, not a substitute for data backups.
From SAP MaxDB version 7.7 with the database tool Database Studio, a GUI is provided for Loader.
