Description: Instan Sync is a desktop tool for high speed file synchronization, mirroring, replication and backups over FTP. 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.
