By default there is a backup file created and updated every 15s if the file 
has been edited. When the file is saved this "backup" file is removed. The 
terminology used in the settings is "Swap file".  (The exception to this is a 
new still unsaved document.)

When you open the original file after a system/kate crash you get a question 
if you want to load the unsaved changes from the swap file.

There is also the an option to always create backups when saving a file. With 
this option enabled Kate will save the original data in the backup before 
writing the new data to the file.

These two option scan be found under:
 Settings->Configure Kate...->Open/save->Advanced
