Synkron – a simple Qt application that allows you to sync folders, for example a flash disk with a folder on your hard disk. Apart from doing synchronizations, it provides many other additional features. The user interface of Synkron is divided into several sections: Synchronize, Multisync, SyncView, Scheduler, Restore, Blacklist and Filters. To switch between these sections, use the toolbar.

Features:
– sync multiple folders at once
– analyze folders to see what is going to be done in sync
– exclude files from sync
– restore files that were overwritten or deleted in previous syncs
– lets you configure your synchronizations in detail
– a cross-platform application that runs on Windows, Mac OS X and Linux

SparkleShare – a file sharing and collaboration app. It works just like Dropbox, and you can run it on your own server. It’s available for Linux distributions, macOS, and Windows.

SparkleShare creates a special folder on your computer. You can add remotely hosted folders (or “projects”) to this folder. These projects will be automatically kept in sync with both the host and all of your peers when someone adds, removes or edits a file.

SparkleShare uses the version control system Git and the large files extension Git LFS, so setting up a host yourself is relatively easy. Using your own host gives you more privacy and control, as well as lots of cheap storage space and higher transfer speeds.

Features:
– Frequently changing project files, like text, office documents, and images
– Tracking and syncing files edited by multiple people
– Reverting a file to any point in its history
– Preventing spying on your files on the server using encryption

The project founder is Hylke Bons.

rsync – an open source utility that provides fast incremental file transfer.

rsync uses the “rsync algorithm” which provides a very fast method for bringing remote files into sync. It does this by sending just the differences in the files across the link, without requiring that both sets of files are present at one of the ends of the link beforehand.

It can copy locally, to/from another host over any remote shell, or to/from a remote rsync daemon. It offers a large number of options that control every aspect of its behavior and permit very flexible specification of the set of files to be copied. It is famous for its delta-transfer algorithm, which reduces the amount of data sent over the network by sending only the differences between the source files and the existing files in the destination. Rsync is widely used for backups and mirroring and as an improved copy command for everyday use.

Some features of rsync:
– can update whole directory trees and filesystems
– optionally preserves symbolic links, hard links, file ownership, permissions, devices and times
– requires no special privileges to install
– internal pipelining reduces latency for multiple files
– can use rsh, ssh or direct sockets as the transport
– supports anonymous rsync which is ideal for mirroring

rsync was originally written by Andrew Tridgell and Paul Mackerras.

Seafile organize files into libraries. Each library can be synced into any desktop computer, including Windows, Mac and Linux. User can also selectively sync any folder.

Access files via Seafile mobile clients, both Android and iOS are supported.

Seafile Drive client let users to extend the local disk space with the massive storage capacity on the Seafile server by mapping storage space on Seafile server as a virtual drive. User can access all files in Seafile immediately, without syncing them.

Libraries and folders can be shared to users or groups, with read-only or read-write permissions. Finer-grained permissions can be set to sub-folders after a folder is shared. Files can be shared to external users via sharing links. Sharing links can be protected by passwords and support setting an expiration date.

Seafile keeps versions for files and snapshots for folders. Users can restore a file or folder to an old version easily. Snapshot for folders is a handy way to protect files against ransomware.

Seafile supports file locking to prevent concurrent editing of files and generating of conflicts files.

Seafile supports online editing and co-authoring for office files (including docx/pptx/xlsx) with integrating with Microsoft Office Online Server or Collabora Online server. Seafile also has a built-in preview for videos, audios, PDFs, images and text files.

Seafile supports client-side end-to-end encryption to protect your data, which is a unique feature that you can rarely find in other solutions.

Seafile supports periodical backup via mysqldump and rsync. It also supports read-time backup via running a dedicated server to get backup from the primary server at near real-time manner.

Seafile contains seaf-fsck tool to help admin to check and remove damaged data,to repair damaged libraries and to export all datas even if System crashes.
