For even greater security and simplicity of backup management, Revisions have been divided into four different types, and each store five backups in total:

• Autosave, these are saved automatically every 5 minutes
• Update, these are saved after every post Update
• Revisions, these are saved only if you click on the Save revision button so basically, it’s up to you if there would be any revision
• Backup, these are Backups created before restoring of any revision
