Securely Upload Files to SFTP Site with PowerShell: A Step-by-Step Guide

Using PowerShell to Upload Files to SFTP Site

In today’s technology-driven world, many businesses and individuals rely on remote server access for file transfers. Whether you’re working on an important project for your company, or you’re a freelancer trying to send files to a client, it’s imperative to have a secure way of transferring files.

This is where Secure File Transfer Protocol (SFTP) comes in. It is a secure method of transferring files over the internet, providing you with a safe and organized way to exchange critical files.

In this article, we will explore how to use PowerShell to upload files to an SFTP site. What is SFTP?

SFTP stands for Secure File Transfer Protocol. It is a network protocol that provides a secure way to transfer files from one computer to another over the internet.

Unlike traditional file transfer methods like FTP, SFTP encrypts the data being transferred, ensuring that it cannot be intercepted by unauthorized parties. This makes it perfect for transferring confidential or sensitive information.

Once you’ve installed the module, you can create an SFTP session. Here is an example:

You’ll need to replace ‘site.example.com’ with the name of the SFTP site you’re connecting to.

2. Scheduled Upload

Here’s how:

Open Task Scheduler by pressing the Windows key + R, typing taskschd.msc, and pressing Enter. Click Create Task.
