Mathusalem for Mac

From Pol-Online:

Mathusalem is a robust and unintrusive backup system, which can be used either as a System Preferences pane or directly as a command line tool.

Mathusalem is complementary to Time Machine as it backups automatically one or more directories of your choice to remote servers in order ensure extra safety of your most important data. Be aware that Mathusalem is not designed to "clone" an entire file system or a subportion of it, but instead to optimally handle everyday simple backups.

• Mathusalem supports a wide range of destinations: local drives, iDisk, WebDAV, AFP, SMB, FTP, SFTP or Amazon S3
• It can generate archives in various formats: sparse or compressed .dmg and CPIO or ZIP archives
• It generates fully self-contained backups i.e. data and settings which makes it possible to access them from any machine or even relocate them
• It is fully open-source which means no proprietary file formats (backup data files are plain XML)
