BestSync - The Powerful File Synchronization, and Continuous File Backup Software

BestSync is an easy-to-use yet powerful and reliable utility for file backup and synchronization. BestSync can backup file to/synchronize local files with FTP/FTPS/FTPES/SFTP folder, WebDAV Collection, ZIP archive and Android folder byBestDAV.  BestSync can synchronize files with cloud storages such as Amazon S3 bucket, Google Storage bucket, Windows Azure container, Rackspace Cloud Files, Google Drive,  Microsoft OneDrive, and DropBox. BestSync can also synchronize Outlook contact/task/email, and Windows Live Mail.

BestSync automatically analyzes folders, detects changed/deleted/moved/renamed files, then synchronizes and backs up only changed files (or Outlook emails).

Before synchronization, BestSync makes backup all the files in your computer that will be replaced or deleted during the synchronization . This is the unique and most important option of BestSync while synchronizing from multiple locations. In this way, original files of all stages can be restored easily, So using BestSync instead of any other synchronization software, you don't need to worry about losing file at any updating stage. BestSync supplies incredible features that are necessary for business usage.

BestSync can also encrypt the changed files by AES 256 bit before upload the files to these public storages.

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.

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 Filters--Only backup the critical data

Sub-folders and files can be specified to be included or excluded from the synchronization.

Support FTP Proxy, HTTP Proxy.

Enterprise users can synchronize local folders with FTP/WebDAV/Amazon S3 Cloud storage on the internet behind the firewall.

Encryption & compression--Keep your data private

BestSync can encrypt the files before uploading them to FTP server and public cloud storage. BestSync can also protect your files before copying 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.

Copy NTFS privilege--Simplify the security management.

In the copy options, there is an option to copy the NTFS privilege.

Support Security Protocols.

Support FTPS (FTP over implicit TLS/SSL), FTPES (FTP over explicit TLS/SSL), SFTP (SSH File Transfer Protocol).

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.

Copy open / locked files

Support "Volume Shadow Copy Service" of Windows XP/2003/VISTA/2008/7/8. 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 openning program.

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.

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.

Parallel Synchronization

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.

Support multi-parts uploading file to Amazon S3, Windows Azure, Rackspace Cloud Files, support upload/download huge file that is larger than 3G bytes.

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, WebDAV, cloud storage, network drive, and shared folder.

File modification Time Syncrhonization.

BestSync supports MDTM, MFMT, SITE UTIME commands to copy the timestamp to the file that is uploaded to FTP server. BestSync also tries to copy the timestamp to the file that is uploaded to WebDAV server and cloud storages (If the this kind of feature is supported by the server).

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.

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.

Verify file after synchronization--Ensure the files be copied successfully.

BestSync can use the verification method (CRC32, MD5) provided by the FTP/WebDAV/cloud storage server to verify if the files have been transferred successfully. If the server does not support the this kind function, BestSync verify the file by comparing the content.

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.

Trigger the task by the insertion event of a removable media, or envet of disk mounting.

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.
