 ## Prerequisites
 
-When DM performs a full data replication task, the DM-worker is bound with only one upstream database. The DM-worker first exports the full amount of data locally, and then imports the data into the downstream database. Therefore, the worker's host space must be large enough to store all upstream tables to be exported. The storage path is specified later when you create the task.

 dmctl is a command-line tool used to control DM clusters. You are recommended to [use dmctl via TiUP](/dm/maintain-dm-using-tiup.md#dmctl).
 
 dmctl supports both the command mode and the interactive mode. For details, see [Maintain DM Clusters Using dmctl](/dm/dmctl-introduction.md#maintain-dm-clusters-using-dmctl).
