InstantSync is a secure desktop tool for high speed file synchronization, mirroring, replication and backups. It 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 guarantees that only new and changed files are transferred, making it perfect solution for web site updates and backups. The Sync Preview feature allows you to see the sync results without actually transferring anything, and helps you to test and fine tune sync task filters and other options. The InstantSync accelerates file transfer with multithreaded transfer engine and on-the-fly file compression. It also supports automatic retries, reconnectes and resume for error free file transfers.
