  • Next step is to run the SSH service by entering the following command.

akarnani@akarnani-PC ~
$ net start cygsshd
The CYGWIN cygsshd service is starting.
The CYGWIN cygsshd service was started successfully.

  • Use any SFTP/FTP application to test. In my case, I will use Filezilla to test the credentials.
  • Enter the IP Address of the server/machine where you installed the Cygwin application. Enter the username as “cyg_server” and password that was created. Also mention the port number as 22.
  • Click on QuickConnect.

  • If you are using it to store CUCM/CUC/UCCX/IM&P backup server, on the right hand side, I would create a folder called Backup and under that Backup Folder, subfolders as CUCM, CUC, UCCX, IM&P.

  • The location on the windows server/system would be the installation path where your Cygwin has been installed.


In our case, the application was installed in C:\ drive so our path is “C:\cygwin\home\cyg_server\

You are all set to take backups now!
