![]() Distributed conflict detection can be achieved by version vectors. For conflict detection, the synchronization software needs to keep a database of the synchronized files. Undetected conflicts can lead to overwriting copies of the file with the most recent version, causing data loss. Conflict detection where a file has been modified on both sources, as opposed to where it has only been modified on one.Compressing any data sent across a network.Encryption for security, especially when synchronizing across the Internet.Common features Ĭommon features of file synchronization systems include: The big advantage of the star topology is that it eliminates the possibility of confusing "spurious conflicts" arising from the fact that a separate archive is maintained by Unison for every pair of hosts that it synchronizes. If you need to do this, the most reliable way to set things up is to organize the machines into a "star topology," with one machine designated as the "hub" and the rest as "spokes," and with each spoke machine synchronizing only with the hub. The Unison Manual describes how to do this: It is possible to synchronize multiple locations by synchronizing them one pair at a time. It is especially useful for mobile workers, or others that work on multiple computers. the "snapshot" feature in Beyond Compare or the "package" feature in Synchronize It!). Synchronization software that only keeps a list of files and the changed files eliminates this problem (e.g. However this suffers from the limit that the synchronized files must physically fit in the portable storage device. The automatic process prevents copying already identical files and thus can be faster and save much time versus a manual copy, and is less error prone. Some backup software also support real-time file sync. BitTorrent Sync, Dropbox and SKYSITE are prominent products. In this article, the term synchronization refers exclusively to two-way file synchronization.įile synchronization is commonly used for home backups on external hard drives or updating for transport on USB flash drives. In two-way file synchronization, updated files are copied in both directions, usually with the purpose of keeping the two locations identical to each other. In one-way file synchronization, also called mirroring, updated files are copied from a source location to one or more target locations, but no files are copied back to the source location.
