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).

Dropbox Offers a Way to Free Data from Mobile Apps with New Sync API Feature for Developers
He found in a recent survey that Apple and Dropbox are the two cloud services most used by U.S. consumers, with 27 percent and 17 percent of just over 2,000 respondents, respectively. Allowing people to control their content across devices from different companies provides one way for Dropbox to stand out, he says.
OpenAFS
AFS is a distributed filesystem product, pioneered at Carnegie Mellon University and supported and developed as a product by Transarc Corporation (now IBM Pittsburgh Labs). It offers a client-server architecture for federated file sharing and replicated read-only content distribution, providing location independence, scalability, security, and transparent migration capabilities. AFS is available for a broad range of heterogeneous systems including UNIX, Linux, MacOS X, and Microsoft Windows
IBM branched the source of the AFS product, and made a copy of the source available for community development and maintenance. They called the release OpenAFS.

File and Data Storage: AFS
AFS Andrew File System is a distributed, networked file system that enables efficient file sharing between clients and servers. AFS files are accessible via the Web or through file transfer programs such as OpenAFS or Fetch Macintosh and SecureFX Windows. Currently all users with a full-service SUNet ID are granted 2 GB of AFS file space. Additional disk space is available by request for faculty-sponsored research including dissertations.

rsnapshot
rsnapshot is a filesystem snapshot utility for making backups of local and remote systems.
Using rsync and hard links, it is possible to keep multiple, full backups instantly available. The disk space required is just a little more than the space of one full backup, plus incrementals.
Depending on your configuration, it is quite possible to set up in just a few minutes. Files can be restored by the users who own them, without the root user getting involved.
