Backups play a very important role in any system. According to its purpose, I can divide it into the following areas:

  database recover
    recover from a complete system failure.
    recover parts of the system to the state it was in before user error.
  
  Audit and analysis
    Create an environment separate from your primary production environment for data auditing or analysis.

  Typical DBA tasks
    Transfers data from one system to another.
    Create a development server or test server based on the specific state of the production server.
