The Cloud Staging Copy Service (CS2) is a REST service packaged with Data Mover. The Cloud Staging Copy Service provides a method of copying data from a source system to a target system through cloud storage. The name of this cloud storage is Cloud Staging Area.
- Takes data backup from the source system to the Cloud Staging Area.
- Copies data from the Cloud Staging Area to the target system.
- Cleans up the backup data from the Cloud Staging Area after the copy task completes.
- Configuring DSC to copy data from the source to the Cloud Staging Area, and from the Cloud Staging Area to the target.
- Creating and executing a DSA backup job to back up data from the source to the Cloud Staging Area.
- Creating and executing DSA restore job to restore data from the Cloud Staging Area to the target.
- Calling DSA to cleanup backup data from the Cloud Staging Area after the DSA restore job completes.
The Cloud Staging Copy Service runs as a service embedded on the Data Mover host. The service provides a REST API that uses port 3443. You do not have to interact directly with the Cloud Staging Copy Service. You interact with the Data Mover interfaces. The Data Mover Daemon and Agent handle the interaction with the Cloud Staging Copy Service. Port 3443 only needs to be open to incoming traffic on the Data Mover host if there is an external Data Mover Agent. Otherwise, all traffic to port 3443 is local.
There are three main supported configurations for running Data Mover DSA jobs with the Cloud Staging Copy Service:
Configuration 1: DSC Running with Cloud Staging Copy Service on the Data Mover Server
Configuration 1 is the default setup when you do not have an existing DSA environment. The bundled DSC and the Cloud Staging Copy Service come with Data Mover are enabled for use.
See Configuring DSC to Run on the Data Mover Server for configuration instructions.
Configuration 2: Data Mover Using Cloud Staging Copy Service and an External DSC
Use configuration 2 when you have an external DSC, one or more of your Data Mover source or target systems is running a version earlier than 16.00, and the Cloud Staging Copy Service is enabled for use on the host.
See Configuring Data Mover to Use an External DSC for configuration instructions.
Configuration 3: DSC Running with Cloud Staging Copy Service on the Data Mover Server and Externally
Use configuration 3 when you have an external DSC, all your Data Mover source and target systems are version 16.00 and later, and the Cloud Staging Copy Service is enabled for use on the host. Here, both the external DSC and the Data Mover bundled DSC can coexist.
See Configuring DSC to Run on the Data Mover Server and Externally for configuration instructions.
