https://www.resilio.com/
Resilio Sync allows you to automatically sync files between computers via secure, distributed technology (P2P bittorrent protocol).
Fast, intelligent file transfers.
Sync skips the cloud and finds the shortest path between devices when transferring data. No Cloud. No uploading to third party servers. Just fast, simple file syncing.
Use your local network
You don't need the Internet to use Sync. Sync can utilize local networks even if the Internet is down or unavailable. You can even set up a router in a place with zero internet access to share data over a private network.
Intelligent synchronization.
Incremental updates
After you edit an existing file, Sync knows how to update only the parts that have changed rather than the entire file. This makes updates much faster, especially for large files.
Continuous synchronization and updating
Keep all of your shared folders up to date all the time across all devices. Updates and changes are synchronized immediately and automatically.
Pause specific folders
You can pause syncing for specific folders, or for everything at once. If you're in a situation with extremely limited connectivity you can turn off everything but the most important folders to ensure that information is synchronized as efficiently as possible.
On-demand access to files.
Save space with placeholder files
When 'Selective Sync' is on, Sync will create placeholder files in your filesystem that can be searched locally. Download only the files you need, when you need them, without having to replicate entire folders on every device. Placeholder files are representations of your files that can be double-clicked and downloaded locally.
Access massive files when you need them
Don't want to sync the entire contents of a folder to your device? Turn on 'Selective Sync' to save space. You can choose to only sync files on-demand, when you need them。

https://www.cis.upenn.edu/~bcpierce/unison/,https://github.com/bcpierce00/unison
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.
Unison shares a number of features with tools such as configuration management packages (CVS, PRCS, Subversion, BitKeeper, etc.), distributed filesystems (Coda, etc.), uni-directional mirroring utilities (rsync, etc.), and other synchronizers (Intellisync, Reconcile, etc). However, there are several points where it differs:
* Unison runs on both Windows and many flavors of Unix (Solaris, Linux, OS X, etc.) systems. Moreover, Unison works across platforms, allowing you to synchronize a Windows laptop with a Unix server, for example.
* 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. Conflicting updates are detected and displayed.
* Unlike a distributed filesystem, Unison is a user-level program: there is no need to modify the kernel or to have superuser privileges on either host.
* Unison works between any pair of machines connected to the internet, communicating over either a direct socket link or tunneling over an encrypted ssh connection. It is careful with network bandwidth, and runs well over slow links such as PPP connections. Transfers of small updates to large files are optimized using a compression protocol similar to rsync.
* Unison is resilient to failure. It is careful to leave the replicas and its own private structures in a sensible state at all times, even in case of abnormal termination or communication failures.
* Unison has a clear and precise specification.
* Unison is free; full source code is available under the GNU Public License。

 https://keybase.io/docs/kbfs
 The Keybase filesystem (KBFS) is a distributed filesystem with end-to-end encryption。
“Distributed” means you can access it from any device.
“Filesystem” means that there is no sync model -- files stream in and out on demand. Among other things, that means that files on KBFS don’t take up space on your devices.
“End-to-end encryption” means that all data stored in KBFS have guaranteed integrity and authentication, and also confidentiality when desired, and that only the people intended to read or write a piece of data can do so. In particular, we (Keybase) cannot change, read, or even know the names of your private files.
“Global namespace” means that each file on KBFS has a single unique path, regardless of the device from which you access it。

https://leastauthority.com/
S4 = Simple Secure Storage Service.
S4 is an Amazon S3-based application of Least-Authority File System, or LAFS. LAFS is a free, open source cloud storage system with verifiable end-to-end security. It distributes your data across multiple servers. Even if some of the servers fail or are taken over by an attacker, the entire filesystem continues to function correctly, preserving your privacy and security.
What is Least-Authority Backup good for?
It is good for securely backing up your data off-site. The "tahoe backup" command inspects your local filesystem for files that have changed since the last time you ran it. It uploads each file that has changed and it creates a directory in LAFS to hold the current "snapshot"—the current version of each of the files. You can browse or access old versions just by browsing the old snapshot directories.
Where is my data stored?
Your data, encrypted, is stored on Amazon's Simple Storage Service (S3), which is a convenient, reliable, and widely understood platform for storage.
Data is replicated according to the following policy decribed in Amazon's Overview of Security Processes:
Data stored in Amazon S3, Amazon SimpleDB, or Amazon Elastic Block Store (EBS) is redundantly stored in multiple physical locations as part of normal operation of those services and at no additional charge. Amazon S3 and Amazon SimpleDB provide object durability by storing objects multiple times across multiple Availability Zones on the initial write and then actively doing further replication in the event of device unavailability or detected bit-rot.
How much do the services cost?
S4 costs $25 per month for unlimited storage, for personal use.

Conclusion

Personally, I’m using Owncloud as FOSS based cloud solution for my file sharing with friends and family. It offers me Calendar, Contacts, and Dropbox like storage. My cloud server has total 5 disks, 2 Gib RAM, and an Intel atom cpu. I use a Debian Linux with RAID 6. I backup my cloud to an external USB drive and currently, testing tarsanp backup service. I’m also planning to try out SparkleShare on the Raspberry Pi soon.
