Back up your data and synchronize PCs, Macs, servers, notebooks, and online storage space.
You can set up as many different jobs as you need and run them manually or using the scheduler. The software works with local hard drives, network drives and any other mounted volumes. In addition, it comes with support for FTP, SSH, WebDAV, Amazon S3, and Google Docs. You can use ZIP compression and data encryption. There are powerful synchronization modes, including Standard Copying, Exact Mirror, and SmartTracking.
The carefully designed GUI makes it an extremely versatile synchronizing and back-up tool. The wealth of features fulfills all requirements that users typically have, while still being easy to use.
What is FreeFileSync?
FreeFileSync is an Open-Source folder comparison and synchronization tool. It is optimized for highest performance and usability without restricted or overloaded UI interfaces.
Key Features
Compare files (bytewise or by date) and synchronize them.
No limitations: An arbitrary number of files can be synchronized.
Unicode support.
Network support.
Built-in support for very long filenames (more than MAX_PATH = 260 characters).
Synchronization database for propagation of deleted files and conflict detection
Support for multiple folder pairs with distinct configuration
Full support for Windows/Linux Symbolic Links and Windows Junction Points.
Lean & easily accessible UI: Highly optimized for speed and huge sets of data.
Algorithms coded in C++ completely.
All progress indicators optimized for maximum performance!
Create Batch Jobs for automated synchronization with or without GUI.
Focus on usability:
Only necessary functionality on UI: no overloaded menus or icon jungle.
Select all folders via drag & drop.
Last used configuration and screen settings are saved automatically.
Maintain and load different configurations by drag & drop, load-button or commandline.
Double-click to start external application (e.g. show file in Windows Explorer)
Copy & paste all grid data as text
Delete superfluous/temporary files directly on main grid.
Right-click context menu.
Comprehensive status information and error reporting
Sort file-lists by name, size or date.
Support for filesizes larger than 4 GB.
Option to move files to Recycle Bin instead of deleting/overwriting them.
Ignore directories "\RECYCLER" and "\System Volume Information" with default Filter. (Windows only)
Localized versions are available for many languages.
Delete before copy: Avoid disc space shortages for large sync-jobs.
Filter functionality to include/exclude files from synchronization (without requiring a re-compare!).
Include/exclude specific files from synchronization temporarily.
Automatically handle daylight saving time changes on FAT/FAT32 volumes.
Portable version available (selectable via installer).
Native 64-Bit version.
Check for updates from within FreeFileSync automatically.
Copy locked files using Windows Volume Shadow Copy Service. (Windows only)
Create regular backups with macros %time%, %date% within directory names
Copy file and folder create/access/modification times when synchronizing
Advanced locking strategy to allow multiple synchronization processes (e.g. multiple writers, same network share)
The NTP Time Server Monitor, available for the operating systems Windows NT/2000/XP/2003 Server, allows the user to configure and control the local NTP service with a userfriendly graphical user interface.
To provide a service that is capable of synchronizing data between two sources without the use of a client.
This project is based on unmodified existing Funambol artifacts and is designed to be installed alongside an existing bundle installation. StS can synchronize data from and to any connector. For full compatibility and customization, the following requirements must be met by a connector.
* All source-specific configuration parameters should be configurable at a granularity of username. (Example: the remote URI of a caldav server should be able to be different for different users).
* All user-specific authentication parameters should support one level of indirection. (Example: for an account in Funambol with username 'A' and password 'B', authentication against a remote data source should be done with username 'C' and password 'D')
* All user-specific configuration parameters should be configurable through a webservice packaged with the connector.
* No dependencies on any configuration files in the default Funambol configuration. Custom User Managers and Officers often have dependencies on these configuration files, but these are easily broken.
Dropbox, at its core, is a simple file synchronization utility that stores your data in the cloud and makes it accessible across Windows, Mac, and Linux machines—or via the web interface from any browser. What sets Dropbox apart from other file syncing tools is that changes are nearly instantaneous, uploads are blazing fast, and it just works.
Foxtrot is an easy and powerful API to use threads with the JavaTM Foundation Classes (JFC/Swing).
The Foxtrot API are based on a new concept, the Synchronous Model, that allow you to easily integrate in your Swing code time-consuming operations without incurring in "GUI-freeze" problem, typical of Swing applications.
While other solutions have been developed to solve this problem, being the SwingWorker (see also here for an update) the most known, they are all based on the Asynchronous Model which, for non-trivial Swing applications, carries several problems such as code asymmetry, bad code readability and difficult exception handling.
The Foxtrot API cleanly solves the problems that solutions based on the Asynchronous Model have, and it's simpler to use.
Your Swing code will immediately benefit of:
* code symmetry and readability
* easy exception handling
* improved mantainability
The Little Book of Semaphores is a free (in both senses of the word) textbook that introduces the principles of synchronization for concurrent programming.
In most computer science curricula, synchronization is a module in an Operating Systems class. OS textbooks present a standard set of problems with a standard set of solutions, but most students don't get a good understanding of the material or the ability to solve similar problems.
The approach of this book is to identify patterns that are useful for a variety of synchronization problems and then show how they can be assembled into solutions. After each problem, the book offers a hint before showing a solution, giving students a better chance of discovering solutions on their own.
The book covers the classical problems, including "Readers-writers", "Producer-consumer", and "Dining Philosophers". In addition, it collects a number of not-so-classical problems, some written by the author and some by other teachers and textbook writers. Readers are invited to create and submit new problems.
