## Introduction

If you want to synchronize files and folders between computers automatically, `lsyncd` is a great option. However, you must configure everything from the command line.
If you want to automatically synchronize files and folders between computers, `lsyncd` is a great option. However, you must configure everything from the command line.

It is a program worth learning for any system administrator.

The best description of `lsyncd` comes from its man page. Slightly paraphrased, `lsyncd` is a lightweight live mirror solution that is not hard to install. It does not require new file system or block devices and does not hamper local file system performance. In short, it mirrors files.

`lsyncd` watches a local directory tree's event monitor interface (`inotify`). It aggregates and combines events for a few seconds and spawns one (or more) process(es) to synchronize the changes. By default, this is `rsync`.

As of this date (Septemer 2025), Rocky Linux 10 with the EPEL (Extra Packages for Enterprise Linux) enabled, does not include the `lsyncd` package. To use `lsyncd` on Rocky Linux 10, you will need to use the **Installing `lsyncd` - source method**. The RPM method is retained here, as it is likely that the EPEL will build this package for version 10 in the future. It never hurts to check to see if the package is available prior to building from source.

You can install `lsyncd` in two ways. Included are descriptions of each method. The RPM tends to lag behind the source packages by a little, but only by a little. The version installed by the RPM method at the time of this writing is 2.2.3-5, whereas the source code version is now 2.3.1. Choose the method you feel the most comfortable with.
