InstantSync is a desktop tool for high speed file synchronization, mirroring, replication, and remote 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 remote 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 filtering options let you limit transferred files by file/folder name, Größe, Datum and attributes. The InstantSync accelerates file transfers with multithreaded transfer engine and on-the-fly file compression. It also supports automatic retries, reconnectes, and resumes for error free file transfers. Extensive logging options with multiple log file rotation schemes are available.
