Using BestSync, publishing your website becomes easy and fast, only changed files are transferred to the server, and the deleted files on one side can be removed automatically by option.
Synchronize folder with WebDAV collection--Online access file
Synchronize only changed files with WebDAV collections in bi-direction.
Automatically download file from/upload files to WebDAV collection.
Synchronize folder with Amazon S3 Bucket--Online access file
Synchronize only changed files with Amazon S3 Bucket in bi-direction.
Automatically download file from/upload files to Amazon S3 Bucket.
Synchronize a folder with a ZIP file with complex filtering functions.
Only changed files are put into the ZIP file, and deleted files are removed from the ZIP file. Support AES (Advanced Encryption Standard) 128Bit/256Bit cryptographic algorithm to protect the zip file with password.
Synchronize with MS Outlook, Windows Mail
Synchronize email, contact, schedule etc with MS Outlook, Windows Mail by USB, FTP etc. BestSync only copies new mails, contacts and schedules.
Run as Windows Service, No need to logon
This is very suitable for a server to backup changed files, and workstation to backup files to a server. When synchronize with the network drive or shared folder. BestSync can impersonate a local user and logon to the network resource.
Copy open / locked files
Support "Volume Shadow Copy Service" of Windows XP/2003/VISTA/2008/Windows 7. Even opened files or locked files, such as SQL data base file, Outlook PST files can be backed up correctly, and no need to close the program.
Real-time Synchronization
Synchronize files immediately after changed. BestSync monitors the change of the folders. When a file is changed, deleted, or renamed, the file is copied to, deleted from, or renamed in the target folder immediately.
Fast Scan! Fast Sync! Fast Download!
- Fast Scan! Scan multiple folders simultaneously to shorten the prepare time.
- Fast Sync! Copy multiple files simultaneously shorten the synchronization time.
- Fast Download! Download one large file in multiple segments by multiple thread.
Avoid disk fragments even copy multiple files simultaneously.
Resume a file transfer from the last break point.
The feature ensures large files to be copied successfully. This feature applies to FTP server, network drive, and shared folder.
Bandwidth control for FTP download and upload.
Limit bandwidth by the preset speed limit graph.
Resolve conflict intelligently and automatically
Detect file copying, deleting and moving, and do the corresponding action automatically.
Encryption & compression--Keep your data private
For example, when you synchronize files to an USB drive in office, the files are encrypted and compressed. And when the files are synchronized to a home PC again, files are decrypted and decompressed. So it is safe even though the USB drive is lost. The default cryptographic algorithm is AES (Advanced Encryption Standard) 256Bit.
Flexible Schedule--Automate your task.
A flexible schedule can be specified to start tasks automatically. You can set any schedule you want! Just set-it-and-forget-it. Automatic synchronization, automatic backup, automatic upload file to FTP server is capable. 
Detecting time zone, Resolving conflicts caused by Daylight Saving Time change, Preserving FTP file timestamp.
Files can be synchronized correctly even the client and server are in different time zones. The timestamp difference caused by the Daylight-Saving-Time change can be ignored by option. Optimized for synchronizing with FileZilla FTP server. Get accurate timestamp from server when download file, and preserve the timestamp when upload file to FTP server.
No file crash! No file lost!
No files will be crashed during synchronization. BestSync uses a temporary file as the target, only the temporary file has been copied successfully, it will become the target file. The files replaced or deleted during synchronization can be backed up and restored later.
Versioning--Keep previous versions
The date and time of synchronization can be used to create a sub-folder to store the backup files, and a backup comment can be attached to the sub-folder. Old versions can be cleared automatically by option.
Preview--Confirm or change the sync action before running
In the preview window, you can modify synchronization action of the files, and confirm the result of the synchronization, or start the comparing tool to view difference between the files of two sides.
Trigger the task by the insertion event of a removable media.
When you insert the USB disk in to the PC, all the updated files are compressed and encrypted to the USB disk. When the synchronization completes, BestSync flushes all the data to the USB disk, it is safe to take the USB out of the PC.
BestSync can modify the task setting automatically if the drive is mounted to a different drive number from the task setting.
(BestSync Portable Version optimized for portable usage, no need to install, just decompress the files to the root folder of the removable drive.)
Works on any file system and media.
Changes and conflicts are detected and corrected automatically by comparing current file status to the previous file status. The file can be in a removable media, an external disk, a server directory, a network sharing directory, a network disk, or a FTP server.
Fast filtering--Backup selected file types
Wildcard patterns can be used as filtering conditions. The wildcard patterns can be part of the file name, extension and wild card characters (*,?,#). A file type selector makes selecting file types very easy.
Include and exclude--Only backup the critical data
Sub-folders and files can be specified to be included or excluded from the synchronization.
Log view--Review the sync history
In the Log view you can view difference between current version and the backup versions, and restore the backup file to the source folder. Export log data to a CSV file or HTML file.
Email Sync Result--Monitor the task remotely
Report the sync result by email. The sync result is a zipped HTML file. BestSync supports SMTP Authentication, such as "AUTH CRAM-MD5" or "AUTH LOGIN".
Full Unicode support
BestSync can synchronize file name include characters of Chinese, Japanese, Korean and more.
Auto power off option to shutdown computer automatically when all the tasks complete.
Command line arguments to lock computer, minimize as task tray icon, start tasks, or shutdown.
Easy to encrypt or decrypt file
Insert a context menu "Encrypt <==> Decrypt" in the Windows Explorer, It is easy to encrypt and compress files or decrypt and decompress files by this menu.
Easy to take out digital camera picture.
Pictures in the digital camera can be automatically moved to a designated folder, and rules can be specified to rename the picture names.
Other features
- Portable paths for removable drives, BestSync uses the volume label and serial number to identify the removable drive. so even the removable drive is mounted to a different disk letter, BestSync can recognize it.
- Support FTP proxy to synchronize file behind the firewall.
- Support HTTP proxy to synchronize file with WebDAV collection, Amazon S3 Cloud storage behind the firewall.
- Automatically logon to network sharing folders before synchronization.
- Automatically reconnect to remote folders if they lose connection during Analyze or Sync.
- Free Space Required Predicted, computes free space needed to complete Sync before you start it.
- Low Memory Requirement, BestSync uses lowest memory than main competitors. See Compare with main competitors.
- Resolving conflicts caused by Daylight Saving Time change.
- Keep the timestamp of the file after uploading it to the FTP server. if one of MDTM, MFMT, SITE UTIME commands is available.
- File Time-stamp Translation for non-preserving file systems, for file systems that do not preserve file modification time when copying, BestSync implements a novel time translation technique that makes time-stamp appear to be preserved by copy action. Run other synchronization tasks after synchronization.
- Run application before and after synchronization. Sequentially run other sync-tasks after synchronization.
- Start sync-tasks from the command line.
