InstantSync is a secure desktop tool for efficient file synchronization, backup, mirroring, and movement over FTPS and SFTP/SSH. Its SyncDB file tracking technology ensures that only new or modified files are transferred, streamlining synchronization and backup processes while maintaining file security.

InstantSync utilizes industry standard FTP / SSL and FTPS over SSH protocols to ensure data safety and encrypts all data with strong encryption ciphers. The underlying smart SyncDB file tracking technology only transfers new and changed files, guaranteeing that you won't waste time transferring redundant data.
With the Sync Preview feature, you can view sync results without actually transferring any files. This feature also helps test and fine tune sync task filters and other options. The InstantSync accelerates file transfers with its multithreaded transfer engine and on-the-fly file compression. Plus, it supports automatic retries, reconnects, and resumes for error-free file transfers.
Lastly, the software provides extensive logging options with multiple log file rotation schemes to ensure that you have all the data you need in one place. In summary, InstantSync is a fantastic software for anyone looking for secure high-speed file synchronization.
