Run File Manager (Windows Explorer on newer versions) in the background while playing. Create a subdirectory off of the Ragnarok directory called 'SAVES' and each time a backup is made, copy all of the LEVEL*.*, RAG_SAV.* and SDATA.* files to the 'SAVES' folder.

To reload after a player's character has died, close Ragnarok, and overwrite the game LEVEL*.*, RAG_SAV.*, and SDATA.* files with the backups found in the 'SAVES' folder and restart the game.
