diagraphephobia 

The fear of deletion; the fear of being deleted. Believing that you are living inside a video game or a computer, and being afraid that you are going to get deleted from existence.

Also applies to the fear of having your important documents, photos, or other files deleted.

Joe believes he lives in some sort of 'Matrix', and constantly suffers from diagraphephobia.

Andy keeps five copies of his files in three different physical locations. He's such a diagraphephobe!
