  • manually backup of a file before editing (with brace expansion like this: cp filename{,.orig})
  • manual copy of the directory structure where file is stored (e.g. cprsync or tar)
  • make a backup of original file in your editor (e.g. set rules in your editor configuration file)
  • the best solution is to use git (or any other version control) to keep track of configuration files (e.g. etckeeper for /etc directory)
