Mathusalem is a robust and unintrusive backup system for Mac OS X Leopard, 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. It is an alternative to the Backup application that comes with .Mac / MobileMe if you need more control or features:

• It supports a wide range of destinations: local drives, iDisk, WebDAV, AFP, 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 can restart a download or upload that failed or was cancelled by the user without having to restart the entire backup
• It runs in low-priority mode on your machine so it doesn’t hang your CPU or hard drive
• It runs only when necessary (it is managed by launchd like other system services)
• It is fully open-source which means no proprietary file formats (backup data files are plain XML)
• It stores passwords in the Keychain
• It reports detailed information on the backup progress
• The command line tool version can be integrated in existing tool chains or used with launchd
