librsync -- network-delta library

•    C

---

librsync is a library for calculating and applying network deltas, with an interface designed to ease integration into diverse network applications. librsync encapsulates the core algorithms of the rsync protocol, which help with efficient calculation of the differences between two files. The rsync algorithm is different from most differencing algorithms because it does not require the presence of the two files to calculate the delta. Instead, it requires a set of checksums of each block of one file, which together form a signature for that file. Blocks at any in the other file which have the same checksum are likely to be identical, and whatever remains is the difference.

Unison - File synchronization tool for Unix and Windows

•    C++

---

Unison is a file-synchronization tool for Unix and Windows. It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other. Unlike simple mirroring or backup utilities, Unison can deal with updates to both replicas of a distributed directory structure. Updates that do not conflict are propagated automatically.

csync2 - cluster synchronization tool

•    C

---

Csync2 is a cluster synchronization tool. It can be used to keep files on multiple hosts in a cluster in sync. Csync2 can handle complex setups with much more than just 2 hosts, handle file deletions and can detect conflicts. It is expedient for HA-clusters, HPC-clusters, COWs and server farms.

Syncthing - Open Source Continuous File Synchronization

•    Go

---

Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet.

csync - A professional file synchronizer for normal users

•    C

---

sync is a lightweight utility to synchronize files between two directories on a system or between multiple systems. It synchronizes bidirectionally and allows the user to keep two copies of files and directories in sync. csync uses widely adopted protocols, such as smb or sftp, so that there is no need for a server component. It is a user-level program which means you don’t need to be a superuser or administrator.

go-sync - gosync is a library for Golang styled around zsync / rsync, written with the intent that it enables efficient differential file transfer in a number of ways

•    Go

---

The ZSync mechanism has the weakness that HTTP1.1 ranged requests are not always well supported by CDN providers and ISP proxies. When issues happen, they're very difficult to respond to correctly in software (if possible at all). Using HTTP 1.0 and fully completed GET requests would be better, if possible. There are some other issues too - ZSync doesn't (as far as I'm aware) solve any issues to do with storage of a files, which can get more and more onerous for large files that are not changing much from one version to another.

bitpocket - "DIY Dropbox" or "2-way directory (r)sync with proper deletion"

•    Shell

---

bitpocket is a small but smart script that does 2-way directory synchronization. It uses rsync to do efficient data transfer and tracks local file creation/removal to avoid known rsync problem when doing 2-way syncing with deletion. bitpocket can use any server which you have ssh access to for its central storage. If you have gigabytes of free disk space on your hosting server you can finally make use of it.
