| description.long | A client-side command-line program that synchronizes files between your local machine and multiple cloud storage services. It supports a wide range of cloud providers and offers features like encryption, checksums, server-side transfers, and bidirectional synchronization. | Unison is an open-source utility that maintains two replicas of files and directories across separate hosts or storage devices, automatically propagating non-conflicting changes while detecting conflicting updates. It works over internet connections including slow links, and allows offline access to already-synchronized data. |
