SugarSync is a cloud service that enables active synchronization of files across computers and other devices for file backup, access, syncing, and sharing from a variety of operating systems, such as Android, iOS, Mac OS X, and Windows devices. For Linux, only a discontinued unofficial third-party client is available.The program automatically refreshes its sync by constantly monitoring changes to files—additions, deletions, edits—and syncs these changes with the SugarSync servers.
