Backup programs?

Hello Linux Gurus, I have seen several people ask or talk about tape drives and such connected to their Linux machines here, but I don't think I have seen anyone mention a backup program? Are there some backup programs available for Linux? Can you use other mediums to store or make backups? Like CDROMs or even another hard drive? I know you could just copy everything from one hard drive to another with Linux, whereas you must have a special program with Windoze for that. end of line Tracer -- ---KMail 1.3--- SuSE Linux v7.2--- Registered Linux User #225206 /tracerb@sprintmail.com/ *Magic Page Products* *Team Amiga* http://home.sprintmail.com/~tracerb
