Teamwork Cloud (TWCloud) is equipped with Data Manager for an administrative process. You need to download the data manager zip file and extract it to the machine where you installed Cassandra. Before using Data Manager, we recommend that you backup your database in the same manner as you do before using the migration tool. You can download the DataManager tool from the same location you download the migration tools for the Cassandra database and UML meta-model.
