In previous articles, we explored different file transfer protocols — from classic FTP and SFTP to modern solutions like S3 and WebDAV. Now let’s take a closer look at Rsync — a powerful tool and protocol that stands out for its efficiency in synchronizing files and directories.
Rsync is perfect for backups, data synchronization, and automation tasks, thanks to its ability to transfer only the modified parts of files.

In previous articles, we covered both classic protocols (FTP, SFTP, SMB) and the modern object storage standard S3. However, there’s another protocol that combines features of traditional file access with HTTP — WebDAV.
This protocol became popular thanks to its simplicity, universality, and ability to work with files as if they were on a local disk, but over the internet.
WebDAV (Web Distributed Authoring and Versioning) is an extension of the HTTP protocol, developed in the late 1990s.

In previous articles, we looked at classic protocols that work with files and folders. But with the rise of cloud technologies, a new, more flexible and scalable approach emerged — object storage, and the de facto standard for it became the Amazon S3 protocol.
S3 (Simple Storage Service) is a protocol originally developed by Amazon Web Services (AWS) for cloud storage. Its success was so great that today the “S3-compatible API” has become an industry standard, supported by dozens of providers (Google Cloud Storage, DigitalOcean Spaces, MinIO, etc.).

When it comes to file sharing not over the internet, but within a local network (at the office or at home), other protocols take the stage. The two main competitors here are: SMB — the king of the Windows world, and NFS — the standard for Unix/Linux.
SMB is a network protocol that provides shared access to files, printers, and other network resources. If you’ve ever opened a shared folder in Windows — you’ve used SMB.

In addition to “heavyweights” like SFTP, there are simpler, narrow-purpose protocols. They aren’t meant for everyday file sharing, but are indispensable in their niches. In this article, we’ll look at two such tools: TFTP and SCP.
As the name suggests, TFTP is a “trivial” or simplified version of FTP. Its main goal is to be as lightweight and easy to implement as possible.

After we figured out insecure FTP, it’s time to meet its secure successors. Here’s where confusion often arises: many people think FTPS and SFTP are the same thing. In reality, these are two completely different protocols — with different histories and principles of operation.
FTPS (FTP over SSL/TLS) is a direct evolution of classic FTP. It takes standard FTP and “wraps” its connections in the cryptographic protocol SSL/TLS (the same one that protects websites via HTTPS).

When it comes to file transfer over a network, the first thing that comes to mind is FTP (File Transfer Protocol) — one of the oldest and most fundamental internet protocols. Despite its age, it’s still in use and serves as a starting point for understanding more complex systems.
FTP (File Transfer Protocol) is a protocol designed for transferring files between computers on a network. It works on the client–server model:

This article is compiled as a “cheat sheet” for SOHO/SMB networks: common issues, their symptoms, causes, quick fixes, and diagnostic checklists. Suitable for both engineers and admins who maintain the MikroTik ↔ Keenetic bundle.
Symptoms: SMB/FTP hangs, speed fluctuates, RDP drops. Causes: incorrect MTU/MSS, fast-path with IPsec, NAT/Firewall errors.

Business process automation has become a standard: whether it’s integrating CRM with messengers, data processing, or DevOps tasks. In this article, we’ll look at what automation tools exist, how they differ, and how to choose the right solution for your needs.
Zapier is one of the oldest and most popular automation services (since 2011). Its strength is its huge ecosystem: more than 5000 integrations, including CRMs, messengers, marketing, and financial tools.

WP-CLI is the official command-line tool for WordPress, allowing you to manage your sites without logging into the admin panel. With WP-CLI, you can install plugins, update WordPress core, manage users, handle database tasks, and even run advanced automation workflows.
In this guide, we’ll explore what WP-CLI is, how to install it, and provide practical examples of its most useful commands.
WP-CLI (WordPress Command Line Interface) is a PHP-based tool that enables direct interaction with WordPress through the terminal. It covers almost all admin tasks and sometimes goes beyond the WordPress dashboard:
