pSync is a command-line file synchronization system designed to keep selected directories aligned between networked hosts. It uses a deliberately manual approach: synchronization happens when the user requests it rather than through a permanently running watcher. This can be useful where predictable transfers are preferred or where synchronizing a file while it is still being edited would be undesirable.
Directories are associated with labels, so paths do not have to be identical on each host. Multiple synchronization directories can be configured, and different remote hosts can be associated with different sets. The same software operates at both ends of the connection, allowing direct synchronization between local machines as well as workflows involving remote or cloud systems.
This is free and open source software.
Key Features
- Uses SSH connections for communication between hosts.
- Supports public key and password authentication.
- Encrypts and compresses transferred data.
- Requires no dedicated pSync server process.
- Does not require administrator privileges for installation.
- Keeps previous states of updated or deleted files as temporary backups.
- Performs synchronization atomically so interrupted operations retain the pre-synchronization state.
- Allows multiple synchronization directories to be configured independently.
- Supports regular files, symbolic links and directories.
- Synchronizes file permissions, creation times and modification times.
- Treats hard links as individual files rather than preserving their link structure.
- Offers an optional progress display when suitable terminal libraries are available.
- Has few external dependencies and is designed with low memory consumption in mind.
- Supports cross-compilation for additional target systems.
