SmartBackup is an alternative lightweight backup application for OS X. Backup multiple source items to a destination folder on an external harddrive, flashdrive or network share, or create a bootable clone of your system. SmartBackup only copies what has changed after the initial run and is very fast in updating your backup or system clone. Archive deleted or changed files in an archive folder during the backup and easily browse available versions of a file and restore them with one click. Use Spotlight Saved Searches to define what you want to backup or what you want to exclude. Automate your backup using iCal, Automator or launch it in commandline mode and include it in launchd items or scripts.
