The file transfer can be started by using

  1. the local jade4dmz client
  2. the job Jade4DMZ_Copy_To_Internet

The jade4dmz client is to be started with 

 jade4dmz.cmd|sh <configuration file name> <section name>

The processes in each data center are controlled and checked by a JADE client in each data center Intranet (JADE1 and JADE2).
These clients run the steps described below and shown in the diagram.

(1)(2) Start JADE clients in the DMZs per SSH

The controlling JADE clients in each data center Intranet (JADE1 and JADE2) start their respective DMZ JADE clients. This is done using SSH.

(3) Copy data to source DMZ

After checking and creating the respective temp folders, the files to be transferred are copied by the JADE1 client from the data center file system to the temp folder in DMZ2. This is done using SFTP.

(4) Transfer data to Internet

The JADE client in DMZ1 carries out the file transfer from DMZ1 via the Internet to DMZ2. This can be done using SFTP, FTP, WebDav, etc.

(5) Delete data from source DMZ

After successful file transfer from DMZ1 to DMZ2, the JADE1 client uses SSH to delete the files, which have been transferred, from DMZ1.

(6) delete data on local

If required, the files on data center 1 will be deleted from the file system by the JADE1 client.

(7) Copy data from target DMZ

After successful file transfer from DMZ1 to DMZ2, the JADE2 client uses SFTP to copy the transferred files from DMZ2 to the data center 2 file system.

(8) Delete data from target DMZ

After files have been transferred to the data center 2 file system the JADE2 client deletes the files from the temp folders in DMZ2 using SSH.
