-# Transfer Data to/from ZIH Systems via Dataport Nodes
-
-To copy large data to/from ZIH systems, the so-called **dataport nodes** should be used. While it is
-possible to transfer small files directly via the login nodes, they are not intended to be used that
-way. Furthermore, longer transfers will hit the CPU time limit on the login nodes, i.e. the process
-get killed. The **dataport nodes** have a better uplink (10 GBit/s) allowing for higher bandwidth. Note
-that you cannot log in via SSH to the dataport nodes, but only use <!-- [NT] currently not available:`scp`, -->`rsync` or `sftp`
-(incl. FTP-clients like e.g. [FileZilla](https://filezilla-project.org/)) on them.
-
-The dataport nodes are reachable under the hostnames 
-
-- `dataport1.hpc.tu-dresden.de` (IP: 141.30.73.4)
-- `dataport2.hpc.tu-dresden.de` (IP: 141.30.73.5)
-
-Through the usage of these dataport nodes, you can bring your data to ZIH HPC systems or get data
-from there - they have access to the different HPC
-[filesystems](../data_lifecycle/file_systems.md#recommendations-for-filesystem-usage).
-As of 11/2023, the following directories are accessible:
-
-- `/home`
-- `/projects`
-- `/data/horse`
-- `/data/walrus`
-- `/data/archiv`
-- (`/data/software`)
-- (`/data/old/home`)
-- (`/data/old/software`)

-## Access From Linux
-
-There are at least three tools to exchange data between your local workstation and ZIH systems. They
-are explained in the following section in more detail.
-
-!!! important
-    The following explanations require that you have already set up your
-    [SSH configuration](../access/ssh_login.md#configuring-default-parameters-for-ssh).
-<!-- [NT] scp currently not available
-### SCP
-
-The tool [`scp`](https://www.man7.org/linux/man-pages/man1/scp.1.html)
-(OpenSSH secure file copy) copies files between hosts on a network. To copy all files
-in a directory, the option `-r` has to be specified.
-
-??? example "Example: Copy a file from your workstation to ZIH systems"
-
-    ```bash
-    marie@local$ scp <file> dataport:<target-location>
-
-    # Add -r to copy whole directory
-    marie@local$ scp -r <directory> dataport:<target-location>
-    ```
-
-    For example, if you want to copy your data file `mydata.csv` to the directory `input` in your
-    home directory, you would use the following:
-
-    ```console
-    marie@local$ scp mydata.csv dataport:input/
-    ```
-
-??? example "Example: Copy a file from ZIH systems to your workstation"
-
-    ```bash
-    marie@local$ scp dataport:<file> <target-location>
-
-    # Add -r to copy whole directory
-    marie@local$ scp -r dataport:<directory> <target-location>
-    ```
-
-    For example, if you have a directory named `output` in your home directory on ZIH systems and
-    you want to copy it to the directory `/tmp` on your workstation, you would use the following:
-
-    ```console
-    marie@local$ scp -r dataport:output /tmp
-    ```
--->
-### SFTP
-
-The tool [`sftp`](https://man7.org/linux/man-pages/man1/sftp.1.html) (OpenSSH secure file transfer)
-is a file transfer program, which performs all operations over an encrypted SSH transport. It may
-use compression to increase performance.
-
-`sftp` is basically a virtual command line, which you could access and exit as follows.
-
-!!! warning "Note"
-    It is important from which point in your directory tree you 'enter' `sftp`! 
-    The current working directory (double ckeck with `pwd`) will be the target folder on your local
-    machine from/to which remote files from the ZIH system will be put/get by `sftp`.
-    The local folder might also be changed during a session with special commands.
-    During the `sftp` session, you can use regular commands like `ls`, `cd`, `pwd` etc. 
-    But if you wish to access your local workstation, these must be prefixed with the letter `l`
-    (`l`ocal), e.g., `lls`, `lcd` or `lpwd`.
-
-```console
-# Enter virtual command line
-marie@local$ sftp dataport
-# Exit virtual command line
-sftp> exit
-# or
-sftp> <Ctrl+D>
-```
-
-??? example "Example: Copy a file from your workstation to ZIH systems"
-
-    ```console
-    marie@local$ cd my/local/work
-    marie@local$ sftp dataport
-    # Copy file
-    sftp> put <file>
-    # Copy directory
-    sftp> put -r <directory>
-    ```
-
-??? example "Example: Copy a file from ZIH systems to your local workstation"
-
-    ```console
-    marie@local$ sftp dataport
-    # Copy file
-    sftp> get <file>
-    # change local (target) directory
-    sftp> lcd /my/local/work
-    # Copy directory
-    sftp> get -r <directory>
-    ```
-
-### Rsync
-
-[`Rsync`](https://man7.org/linux/man-pages/man1/rsync.1.html), is a fast and extraordinarily
-versatile file copying tool. It can copy locally, to/from another host over any remote shell, or
-to/from a remote `rsync` daemon. It is famous for its delta-transfer algorithm, which reduces the
-amount of data sent over the network by sending only the differences between the source files and
-the existing files in the destination.
-
-Type following commands in the terminal when you are in the directory of
-the local machine.
-
-??? example "Example: Copy a file from your workstation to ZIH systems"
-
-    ```console
-    # Copy file
-    marie@local$ rsync <file> dataport:<target-location>
-    # Copy directory
-    marie@local$ rsync -r <directory> dataport:<target-location>
-    ```
-
-??? example "Example: Copy a file from ZIH systems to your local workstation"
-
-    ```console
-    # Copy file
-    marie@local$ rsync dataport:<file> <target-location>
-    # Copy directory
-    marie@local$ rsync -r dataport:<directory> <target-location>
-    ```

-## Access From Windows
-
-### Command Line
-
-Windows 10 (1809 and higher) comes with a
-[built-in OpenSSH support](https://docs.microsoft.com/en-us/windows-server/administration/openssh/openssh_overview)
-including the above described <!--[SCP](#scp) and -->[SFTP](#sftp).
-
-### GUI - Using WinSCP
-
-First you have to install [WinSCP](http://winscp.net/eng/download.php).
-
-Then you have to execute the WinSCP application and configure some
-option as described below.
-
-<!-- screenshots will have to be updated-->

-After your connection succeeded, you can copy files from your local workstation to ZIH systems and
-the other way around.
