Lsyncd
lsyncd is a synchronization service and background daemon that monitors local directories for changes and mirrors them to remote targets in real time. It operates as a sync manager that orchestrates the movement of local data to remote hosts, ensuring data consistency through automated mirroring.
The project uses an embedded Lua scripting engine to define configuration logic, allowing for custom synchronization actions and layered rule definitions. It leverages rsync for delta-transfers to minimize bandwidth and utilizes SSH for secure encrypted communication with remote servers.
The service employs event-driven directory monitoring and buffered event aggregation to trigger transfers without constant polling. This ensures that filesystem changes are collected and synchronized efficiently to remote shares while preserving file ownership.
Features
- Local Directory Synchronizations - Monitors local folders for changes and mirrors them to remote targets in real time via a background daemon.
- Real-Time Synchronization - Ensures local directories and remote targets stay in sync by transferring files immediately upon detecting changes.
- SSH-Based Remote Execution - Establishes secure encrypted SSH channels to execute synchronization commands on remote target hosts.
- SSH Data Transfers - Transfers files to remote hosts over secure SSH connections to ensure encrypted and optimized data movement.
- Background Daemons - Runs as a persistent background process to ensure continuous directory synchronization without needing an active terminal session.
- Directory Monitoring Daemons - A background daemon that monitors local directory changes and mirrors them to remote targets using rsync.
- Filesystem Change Monitors - Tracks local filesystem changes in real time to trigger synchronization tasks instead of relying on periodic polling.
- RSync Data Synchronizations - Integrates rsync to efficiently move local data to remote shares while preserving file ownership.
- RSync - Uses rsync's delta-transfer protocol to minimize bandwidth by transmitting only the modified blocks of files.
- Remote Server Mirroring - Maintains an exact copy of local folders on remote hosts to ensure data consistency across different machines.
- Event Buffering - Aggregates filesystem events over a short window to prevent redundant data transfers during high-frequency file writes.
- SSH Transfer Orchestrators - Automates the movement of local data to remote hosts using secure shell connections as the transport layer.
- Rule-Based Mirroring - Provides programmable rules via Lua or shell scripts to customize how local directories are mirrored to remote targets.
- Embedded Lua Scripting - Integrates an embedded Lua engine to allow users to define complex, programmable synchronization rules and behaviors.
- Synchronization Action Definitions - Allows the definition of flexible synchronization behaviors using shell scripts or Lua code.
- Lua-Configurable Sync Managers - Operates as a synchronization service that uses Lua scripts to define custom behaviors and action configurations.
- Backup Solutions - Synchronizes file changes between systems using rsync.
