Data transfer has become a common operation in the modern-day IT landscape.

You must be dealing with a massive amount of data that involves collecting, managing, and transferring it to reliable storage.

Now, the problem is that transferring large volumes of data requires plenty of time and resources, and you can never rule out cybersecurity risks.   

Therefore, as a system administrator or developer, you need to ensure data transfer is efficient, correct, and, most importantly, secure.  

Fortunately, many advanced ways are available to perform quick and safe data transfer, such as FTP, SFTP, and more. And knowing about these technologies and services or FTP/SFTP clients will ease your work while ensuring data transfer is fast, secure, and smooth.

So, let’s talk about FTP and SFTP first before we delve deeper.

What are FTP and SFTP?

11 FTP/SFTP Clients to Know as a Sysadmin and Developer  Development Sysadmin

File Transfer Protocol (FTP) is a network protocol leveraged to transfer data or files between a server and a client in a computer network.

FTP follows a client-server architecture with separate data connections and control between the server and the client. Users need to authenticate themselves using a sign-in protocol, generally, a username and a password. However, you can also connect to FTP anonymously, provided the server has a configuration to permit it.

SSH File Transfer Protocol (SFTP), also called Secure File Transfer Protocol, is also a network protocol for file access, transfer, and management over a reliable and secure medium.

Here, SSH means Secure Socket Shell or Secure Shell protocol, a cryptographic protocol that offers secure access to a computer in an unsafe network.

SFTP is considered more secure than FTP.

What are the uses of FTP and SFTP?

You can find many use cases of FTP and SFTP involving file transfer from one computer to another, managing files over a remote system, and more. It includes:

  • File sharing with SFTP to meet regulatory or compliance requirements such as FIPS, HIPAA, etc.
  • Uploading a file to a Content Management System (CMS) such as Magento, WordPress, etc.
  • For server administration
  • To achieve firmware upgrades 

How to use FTP/SFTP?
