    Hi and welcome,

    This is a wide field.
    A backup allows you to go restore data to a previous state.
    In that sense, raids and db mirroring do not apply.
    These do:

    - Filebackup
    This can be simple commands (cp, rsync)
    or scripts for one or two machines (rsync, rsnapshot)
    or tools like bacula, which can cover whole networks of machines.

    - filesystem snapshots
    Via lvm or as feature of certain filesystems (btrfs)

    - diskimages
    dd, partimage, partclone, clonezilla can create those.

    - revision control systems like subversion or git
    While these need backup themselves, they can be used as backup from a users point of view.

    - Database dumps
    Speaks for itself.


    Can you give more information, what your scope is?
    - what do you want to backup
    - how much data is expected for a full, incremental, differential run
    - how many machines are involved and what are their purposes
    - how often and when is the backup scheduled
    - etc
    You must always face the curtain with a bow.
