Unison, alternative Linux à Windows Live Sync
Mis à jour le
Notre avis
Unison is a solid replacement for Windows Live Sync for users who need reliable bidirectional folder sync and are comfortable with a command‑line or simple GUI tool. It works on Linux, Windows and macOS, supports local and SSH‑based remote sync, and offers fine‑grained include/exclude rules. It lacks a built‑in cloud service, so you must provide your own transport (e.g., a shared folder, SSH server, or third‑party storage). If you are okay with managing the transport yourself, Unison will meet the core needs of most former Windows Live Sync users.

Ce qui fonctionne pareil
- Bidirectional folder synchronization
- Cross‑platform support (Linux, Windows, macOS)
- Conflict detection and configurable resolution
- Ability to sync over LAN or the internet (via SSH or shared drives)
- Free/open‑source licensing
Ce qui change
- No native cloud storage; you must supply the transport layer yourself
- No automatic background service on Windows like the original Live Sync client
- GUI is optional and less polished than a dedicated cloud client
- No built‑in versioning or history of previous sync states
- Requires manual setup of include/exclude rules; no simple “sync this folder” wizard
Ouvrir vos fichiers Windows Live Sync
Windows Live Sync did not use a proprietary file format; it simply copied files to the cloud. Unison works directly on the filesystem, so there is nothing to import or export. Existing files synced by Live Sync can be placed in the same directories and Unison will treat them like any other files.
Passer de Windows Live Sync à Unison, étape par étape
- Install Unison from your distribution’s repository or via Flatpak.
- Create a profile for each folder pair you want to keep in sync.
- If syncing over the internet, set up SSH access to the remote host and add the appropriate servercmd line.
- Run
unison -ui text <profile>once to verify the initial sync and resolve any conflicts. - Optionally schedule the command with cron or systemd timers for automatic periodic sync.

Can Unison sync with cloud services like Dropbox or Google Drive?
Unison can sync any directory that the operating system can see, so you can point it at a local Dropbox or Google Drive folder, but it does not integrate directly with those services’ APIs.
Is a GUI required to use Unison?
No. Unison ships with a text‑mode interface and several third‑party GUIs; the command line works fine for most tasks.
How does Unison handle file deletions?
Deletions are treated as changes; they are propagated to the other replica unless you exclude the path or use the ‘ignore’ option.
