Lsyncd has the feature of syncing from one source to multiple targets. Lsyncd aggregates events up to 1000 separate events, or a 15-second delay before synchronizing, whichever happens first, so our changes may not be synced immediately. $ echo "This is line 2" > sample/source/file01.bin If we edit files in the source directory, lsyncd will automatically reflect it in the target directory: $ cat sample/source/file01.bin $ lsyncd -rsync /home/baeldung/sample/source /home/baeldung/sample/targetġ5:41:03 Normal: - Startup, daemonizing. The command above will copy/mirror the source directory recursively to the target directory: $ tree sample If the target directory is on a different machine: $ lsyncd -rsyncssh /home/baeldung/sample/source/ target-path/ Let’s set up a local lsync: $ lsyncd -rsync /home/baeldung/sample/source /home/baeldung/sample/target Our ~/sample/source directory will now sync to ~/sample/target directory every minute. The script removed the files in the target directory successfully. * Create sync jobs via GUI to synchronize automatically (can be scheduled or executed directly).Let’s delete a file ( ~/sample/source/file01.bin) from the source to see if it will also delete the same file from the target: $ rm sample/source/file01.bin * Include/exclude specific files from synchronization manually. * Filter functionality to include/exclude files from synchronization (without re-compare!). Copy locked files (Volume Shadow Copy Service) Detect conflicts and propagate deletions. Features: Detect moved and renamed files and folders. * Delete before copy: Avoid disc space shortages with large sync-operations. FreeFileSync is a program that lets you synchronize files and folders. * Automatically ignore directories “RECYCLER” and “System Volume Information” when comparing and syncing. * UTC (coordinated world time) is used when comparing file times avoiding problems with time zones or daylight saving time. The UI makes it easy to specify entire subfolders to sync to the right or left or exclude temporarily. For 2-way sync it builds a hidden '.sync.ffsdb' database in each root that enables it to speed up sync when files have been renamed, and determine in which direction to sync new or deleted files. * Option to move files to Recycle Bin instead of deleting/overwriting them. FreeFileSync does 1-way mirror and 2-way sync. ![]() * Easy configurable commandline mode for automated synchronization. ![]() * Display statistical data: total filesizes, amount of bytes that will be transfered with the current settings. EaseUS EverySync automatically synchronizes files or file folders on multiple machines.EaseUS file sync program makes data backup & file sync on your time-based schedule and automates syncs to run in real-time when there is any change to your data.EaseUS EverySync makes easy cloud storage file sync to allow access to your data anywhere. You can also change how the files are synced with the settings button. * Progress indicators, status information and error reporting. Step 1: Make sure your server is accessible and mounted (right click 'This PC' in Explorer to 'Map Network Drive') Step 2: Download both FreeFileSync and RealTimeSync Step 3: In FreeFileSync, set your source folder on the left with the corresponding server folder on the right. * Maintain and load different configurations by drag&drop, load-button or commandline. * Last configuration and screen settings are saved automatically. * Subfolders are also synchronized, including empty folders. ![]() * Compare files (bytewise or by date) and synchronize them. File comparison can be done by either file size and date or bytewise. Freefilesync comes with both as installer and a zip archive, the zip archive contains the app, you can use the app with out installing like a portable app. We’ll be using a cron job to trigger the sync process with rsync / unison / FreeFileSync periodically and inotifywait or lsyncd to sync on change. Sync works in one way or two way or you can specify custom syncing. In this tutorial, we’ll look at several methods to sync files one-way periodically or when we detect some changes in the files or directories. The simple UI makes it easy to see the app, just compare two folders and start synchronize. Folders can be added by drag and drop to the UI. FreeFileSync is a folder comparison and synchronization utility.
