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.
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)
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
- etcYou must always face the curtain with a bow.
