Description:

Syncany is an open-source file synchronization and filesharing
application. It allows users to backup and share certain folders of
their workstations using any kind of storage, e.g. FTP, Amazon S3 or
Google Storage.

While the basic idea is similar to Dropbox and JungleDisk, 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.

- Arbitrary storage: Syncany uses a plug-in based storage system. It can
be used with any type of remote storage.
