AutoBackups is a Sublime Text 2/3 plugin, which automatically save a backup copy every time you save or open (if backup file not exists) a file. (Like Dreamweaver)
When you edit text files (scripts, prose, whatever) you often find yourself wishing for an last version. Ever accidentally deleted a chunk from an important configuration file, or wished you could roll back a document a few hours? This plugin takes a copy of file you open/save and copies it into a backup directory structure, ensuring that you never lose an last version of a file.
