![]() ![]() The basic gist is that the Lsyncd service runs on each Linux host. You can use Lsyncd in combination with Rsync or Rsync-ssh to mirror 1 Linux server to another. If you’d like to see a live sync Resilio demo, please get in touch with us. ![]() Keep reading to learn about the pro’s and con’s of lsyncd (plus rsync or rsync-ssh) and how it compares to Resilio Connect. And reliability combined with centralized management make deploying files a hands-free operation. We have customers automatically synchronizing many thousands of servers in real-time. Plus you get built in automation (also exposed via scripting and APIs) that scales the real-time synchronization process to as many endpoints as you can deploy. The Resilio management console and Resilio agents run on a variety of Linux distros. Resilio Connect is by far the fastest and most scalable offering on the market so it’s on the high end when considering lsyncd and rsync alternatives. The solution runs on Linux but is also cross-platform and runs on most popular operating systems. Real-time can be configured and intervals set to near zero on the peers. Git has specific instructions for creating this for your OS.Īnother approach, in stark contrast, and enterprise-capable: Resilio Connect. ![]() From there you can use makepkg and sudo to create your package and cd into lsyncd. Under axkibe slash lsyncd.git (git clone ) you can clone the source code to your Linux environment. The variety of programs that can work with Lsyncd are described in the Lsyncd docs on Github. One roll-your-own approach to this for Linux is Lsyncd + another sync tool like Rsync. Near-real-time refers to synchronizing changes as fast as possible: this could be within seconds or within a reasonable time-frame, based on your “real-time” requirements. You’ll want to be comfortable editing configuration files (nf contains the Lsyncd configuration) and writing scripts to call Rsync, rsync-ssh, or programs like lsyncd -nodaemon. In summary, given the above caveats, if you’re a Linux guru and you like scripting, don’t have a business critical project, and don’t need to sync larger data sets for file systems, then Lsyncd may suffice. If the source or target goes down, your sync job goes down with it. SPOF: The design, like many traditional point-to-point file sync tools (pick your vendor) is a single point of failure.Limited applicability: Got big files or many files? Need to sync to Windows or Mac? Need to sync two-way or N-way? Or to more than a single endpoint? Good luck.It was designed to replicate changes from one sysetm to another. Poor scalability: Save pthreads or stuffing more vRAM or vCPU in a box, Lsync won’t scale beyond a single system.Poor management and diagnostic tools: If anything goes wrong in your script such as a loop, there’s no easy way to diagnose or troubleshoot what’s happening.You can only sync one-way from a source to a target between 2 servers. Also, it is not be a good fit for large-scale deployments. The bad news is that you’ll be building, scripting, troubleshooting and supporting lsyncd. So if that type of mirror solution for Linux is what you’re looking for, Lsyncd may be worth a look. Lsyncd propagates changes from 1 Linux system to another to keep the remote (target) server in sync with the local (source) server. The good news is that Lsync provides a basic, automated (via scripting), one-way, semi-current (within a minute or so) sync capability. This is done through scripting commands in an Lsyncd configuration file (nf). Lsyncd was first released in 2008 by Mirko Vogt, and it has since been developed and maintained by a community of contributors on Github. Live syncing refers to the process of listening for and relaying file and directory changes on a source server (sometimes referred to as a master) to another program like Rsync (or Rsync-ssh), which handles the actual sync between systems. Lynscd may not be that popular, but it does serve a purpose. Or a live syncing logo similar to the BSD devil, beastie. Lsyncd stands for Live Syncing Daemon. I’m curious why I’ve never seen a bumper sticker called Live Sync or Daemon. ![]()
