syncany - Cloud storage/filesharing app focusing on security and storage abstraction
Syncany is an open-source cloud storage and filesharing application.
It allows users to backup and share certain folders of their workstations
using any kind of storage, e.g. FTP, SFTP, WebDAV, Amazon S3 and Samba.
While the basic idea is similar to Dropbox, Syncany is open-source and
additionally provides data encryption and more flexibility in terms of
storage type and provider:
* Data encryption: Syncany encrypts the files locally, so that any
online storage can be used even for sensitive data.
* Any storage: Syncany uses a plug-in based storage system. It can
be used with any type of remote storage.
