Lsyncd
Lsyncd 是一个事件驱动的目录同步守护进程，它监控本地文件系统变更以将数据镜像到远程服务器。它作为一个可自定义的同步编排器，监视文件创建、修改和删除，以触发自动化同步任务或用户定义的脚本。
该工具专门自动化 rsync 工作流，利用安全 Shell 连接在远程目标上维护本地数据的一致副本。它通过执行远程文件管理（如重命名和删除）来优化数据传输，从而避免不必要的重新传输。
该系统的功能包括跨不同操作系统（包括 macOS）的实时文件系统监控。它通过评估进程退出代码来管理同步生命周期，以确定任务是应该重试还是终止。用户可以定义自定义同步逻辑，并将特定的文件系统事件映射到外部脚本或 Shell 命令。
Features
- RSync - Utilizes the rsync utility to efficiently mirror local files to remote targets.
- Remote Server Mirroring - Provides automated mirroring of local directories to remote servers to maintain consistent data copies.
- Local Filesystem Authoritative Mirroring - Mirrors local files to a remote target by treating the local filesystem as the authoritative source.
- Event-Driven Task Execution - Triggers shell commands or scripts automatically in response to specific local filesystem events.
- Real-Time Synchronization - Ensures remote mirrors reflect local changes immediately using low-latency filesystem event monitoring.
- SSH Directory Syncs - Maintains synchronization between local and remote directories over SSH based on filesystem changes.
- Event-Driven Scripting - Automatically executes user-defined scripts in response to local filesystem events like file creation or deletion.
- SSH-Based Remote Execution - Executes remote commands over secure shell connections to manage files on target nodes without re-transferring data.
- Event-to-Action Mappings - Allows mapping specific filesystem events to custom user-defined scripts or shell commands via configuration.
- Filesystem Change Monitors - Tracks modifications to files and directories in real time using native OS kernels to trigger synchronization.
- RSync Data Synchronizations - Implements a daemon that uses the RSync protocol to synchronize local changes to remote targets based on filesystem events.
- Remote File Rename and Delete Operations - Performs file renames and deletions on remote servers over secure connections to optimize data transmission.
- Subprocess Orchestrators - Spawns and manages external shell processes and sync utilities like rsync to perform data movement.
- Sync and Forwarding Orchestration - Orchestrates file synchronization and associated actions based on user-defined configuration rules.
- Synchronization Action Definitions - Enables users to define custom synchronization logic and rules via configuration files and shell scripts.
- Event-Driven Rsync Workflows - Automates rsync workflows to synchronize data to remote targets triggered by local filesystem events.
- Command Line Tools - Listed in the “Command Line Tools” section of the The Book Of Secret Knowledge awesome list.
