Sync Algorithm
- File Mod Time Translation For Non-Preserving File Systems
For file systems that do not preserve file modification time when copying, GoodSync implements a novel time translation technique that make mod time appear to be preserved by copy action. - Time Shifts Are Detected And Fixed
When modification time of number of files is different by the same whole number of hours, GoodSync can correct file modification time without copying the file. - Embedded Jobs Handled
One folder and its subfolders can participate in more than one sync job, some of these jobs syncing folders above or below this folder. For instance, you can sync folder C:\work\project to USB key, sync folder C:\work to portable hard drive and file state changes registered in one job will be accounted for by the other job. - Chained Synchronization for Multiple Devices
Changes performed by GoodSync can be transferred to other computers/devices.
Example: You can synchronize files between computers A and B which are not connected to each other, by synchronizing Computer A to a USB disk, and then syncing USB disk to computer B. - Lightning Fast Speed, Low Memory Requirement
GoodSync is much faster than other synchronization programs and it takes less memory. It can analyze a job with 1M files and folders on each side in less than 10 minutes on only 500 Mb of memory. - File Monitoring Is Used in Real-Time Sync
If user selects Real-Time Sync option and file system can do file monitoring, then file monitoring is used to speed up Analyze. - No File Monitoring Is Required
Changes in files are automatically detected by comparing current file status to the stored file status, so no OS-based file monitoring is required.
Copying Files
- Compression in NTFS
GoodSync can compress one or both sync folders using NTFS compression. - Copy Locked Files
GoodSync can copy locked files using Volume Shadow Copy Service. - Copy Symbolic Links or Drill Down
Symbolic links can be copied as links (copy as is) or as files to which they are pointing. - Copy Attributes and ACL (Access Control List, Owner)
GoodSync copies file attributes and ACL, if requested. - Copy Extended Attributes
GoodSync copies extended attributes of files that are used to store custom icons on Mac. - Fixing Access Denied Errors
A part of GoodSync always runs in elevated mode, so it handles file operations that would otherwise cause Access Denied error and require User Account Control elevation. - Unix Diff Integrated
Can call Unix Diff utility to compare text file line by line. - Encrypt Files In Transit
If you backup to cloud servers using Secure (SSL) option then all files transferred are encrypted en route. - Encrypt Files At-Rest
Encrypt file names and/or bodies using 256-bit AES encryption.
User Interface
- Bookmarks make it easier to get to password-protected servers
You can save any server address and credentials into Bookmark and later use it in a job.
GoodSync also shows virtual bookmarks, a list of non-repeating credentials assembled from your sync jobs. - Visual Comparison of Folder Trees Made Easy
File and folders from both sides are displayed in one combined tree making visual comparison easy. - Slice It and Dice It With Tree Views
File to be synced are sorted into different groups (All, Left to Right, Right to Left, New Files, Deleted Files, Excluded, etc) and Tree Views allow to see all these groups in File Tree. - Job List Pane as Main Control Panel
Job List pane shows status of all jobs. - Select Multiple Folders to Sync
You can select multiple folders to sync (not just one), in one job. - Select Individual Files to Sync

GoodSync uploads and downloads files and folders with non-latin names just fine. It works correctly on Windows, networks, FTP, SFTP, WebDAV, S3 file servers. We use UTF-8 to encode file and folder names in transfer and UNICODE internally.
File Sync
If you’re someone who uses multiple computers and devices for work, school or fun, you know what a headache it is to keep your files up-to-date in all locations. GoodSync’s File Sync feature ensures that folders in two or more separate locations contain identical up-to-date files. If you add, change, or delete a file from one location, the synchronization process will add, change, or delete the same file at the other location(s).
Our software will not only synchronize all your data, but also analyze, filter, and display results through a user-friendly interface, ensuring you avoid duplicates and synchronize only the files that you need!
Keeping Files Synced
- When two or more locations are synchronized with GoodSync, no matter where your files are located, the most current versions of those files is available at all locations, regardless of where and when it was last modified.
- Although it is possible to manually copy files between directories, using GoodSync is faster and safer, as you are much less likely to accidentally delete files. Our powerful algorithm takes all the guesswork out of keeping your important files up-to-date, so don’t get caught without GoodSync!
Why Use GoodSync for File Synchronization?
- • Convenience: You can choose to automate the syncing process at a given time of day or when a particular system action occurs, like when a USB drive is inserted or during system startup.
- • Options: GoodSync can synchronize files located on a PC, Mac, smartphone, tablet, hard drive, network, USB, FTP, SFTP, WebDAV, or Amazon S3. The synchronization can be done locally, through a network or through the internet.
- • Unparalleled Technology: GoodSync's sophisticated algorithm and bit-by-bit synchronization ensures complete accuracy and protects against data loss. GoodSync is scalable enough to withstand synchronization jobs ranging from five files to five million files without fail.
- • No Monthly Fees: Unlike many other backup solutions, we do not charge monthly fees for backups.
File Backup Software
Thanks to GoodSync, backing up the files on your computer has never been easier or faster. With our award-winning backup software, you get the peace of mind knowing that your important documents and files are safe, even if you accidentally delete them or your computer crashes.
With GoodSync’s user-friendly interface, you can easily back up files by copying from a source folder on your computer to a destination folder. You have a variety of options for where the destination folder is located, plus all GoodSync file backups can be completed locally, through a network, or over the internet.
Restoring Your Files
- One of the best features of GoodSync is how easy it is to restore lost or corrupted files. Through the GoodSync backup software, you can quickly and completely restore a computer following a crash or have the flexibility to restore only a small number of files after they have been accidentally deleted or corrupted.
Why Use GoodSync for File Backup?
- • Speed and Efficiency: Our software employs a sophisticated synchronization algorithm that detects which files in the source folder have been changed since the last backup, and only backs up those files that have been changed by the user. This is much more efficient than backing up the entire source folder every time files are backed up like traditional backup services.
- • Access: Unlike traditional file backup services, GoodSync directly backs up and updates the actual data files themselves in their native formats rather than images of the source data. In the event of data loss in the source folder, files in the destination folder can be launched immediately, thereby reducing any unnecessary downtime.
- • Options: GoodSync gives you the most options for backing up your files- use what works best for you! GoodSync supports backup to flash drives, other laptops and desktops, external hard drives, FTP, SFTP, WebDAV and Amazon S3.
- • Convenience: GoodSync’s backup functionality can be set up to run automatically, eliminating the need to remember to run backups. GoodSync remembers for you!
- • No Monthly Fees: Unlike many other backup solutions, we do not charge monthly fees for backups.
GoodSync Connect
GoodSync Connect allows users to connect two computers directly, in a peer-to-peer style, without using intermediate servers that store files. This results in several benefits, including:
Increased Upload and Download Speed
- Many cloud based services regulate the speed in which you can upload and download your data, making transferring large files or numerous files very time consuming. With GoodSync Connect you'll sync files at the speed of your connection, not throttled by any intermediate server.
Unlimited Sync and Storage and no Additional Expense
- With GoodSync Connect you are storing your data on your own computers, not on 3rd party servers as in traditional cloud-based services. Therefore your only storage limitation is that of your computer.
And since your data is not stored on somebody else's server, you do not have to pay anybody for extra storage.
And since your data is not stored on somebody else's server, you do not have to pay anybody for extra storage.
- Your data is stored on your directly connected computers. There's no need to worry about storing your personal information in the cloud where others may see it.
More Secure than via 3rd party Server
- Your data is stored on your directly connected computers. There's no need to worry about storing your personal information in the cloud where others may see it.
Faster Synchronization of Large Files
- When a user changes a file, most backup and synchronization programs can identify that the file has changed and upload/download the entire file. With GoodSync 9, we identify the specific parts of the file that have changed and synchronize only those changes. This significantly increases the speed of backups and synchronization of small changes in large files such as Outlook and QuickBooks files.
Resumable Upload and Download
- If you stop download or upload or it is stopped due to connection loss, it can be resumed from the point where you stopped it, even if you stopped it inside the file.
Encryption in Transfer
- Users have an option to choose Secure Mode to ensure the communication channel between your computers is encrypted using SSL.
Platform independent and interoperable
- Works on Windows, Mac, and Linux. Syncs files between Windows and Windows, Mac and Windows, Mac and Mac, etc.
Other Features and Benefits
- * Global Discovery: GoodSync servers are listable per user via Mediator server.
* Local Discovery of GoodSync servers without any mediation server.
* Recovery: Fast automatic recovery from lost connections.
* Forwarder: GoodSync client can get to inaccessible GS Server via Forwarder.
* Idempotency: If the same transaction is retried many times, only one action will be taken.
* Compute MD5 checksum of files server-side, send it to client.
* Copy Security (ACL) and other attributes of files.
* Proxies handled: GoodSync client can connect via proxy servers.
* Increased password security: Use digest authentication.
How Does GoodSync Connect Work?
- Simply setup a GoodSync Connect account, install GoodSync 9 on each computer you want to sync, and these computers will be able to talk to each other and perform peer-to-peer synchronization.
Block-Level Synchronization
Siber Systems has released version 9 of GoodSync that allows for P2P (peer-to-peer) connection between two computers. It enables two computers to connect directly with each other to synchronize or backup files directly with no need to store files intermediately at a central location (e.g., a web server). Different connection methods are implemented for computers located on the same LAN and computers that need to connect to each other across the Internet. Now that two computers running GoodSync can talk to each other, block-level transfer/synchronization is finally possible. This technology extremely reduces network traffic while synchronizing large files that do not significantly change between synchronizations. Examples for such files are: databases, logs and email archives. Block-Level Synchronization is especially important for our large enterprise customers, but may be very useful for consumers as well.
Block-level transfer is an optimized method of file transfer that focuses on providing high performance transfers across our GSTP protocol. With block-level transfers, only the parts of a file are transferred that differ. When GoodSync identifies a file that has been updated or changed it calculates the exact binary data within that file and sends only the changed information. This way each file transfer only passes the data required to update the destination file. A normal file transfer would send the entire file, even if only small parts of the file have changed.
- Let's say we have a 1GB log file. A new action occurs and a single line is appended to our log file. A normal file sync operation would recognize that the file has changed and would then transfer the entire 1GB file to the destination. This is quite an extensive operation especially when you consider that only a few bytes have been added to the file. Now with block-level transfer, GoodSync will identify the exact bytes that changed (our new line in this example), and only send that data. A transfer that would have taken almost an hour to complete has now been reduced to just seconds!
