That is one of the reasons I am thinking about having /home on NILFS2 ([1] a log-structured file system) in my dabbing with my own Linux distribution. When you have constant snapshots then ransomware can't do much, can it?

- hawski 9y agoLog-structured file systems work by treating disk space as circular log. They only append and then wrap around. Snapshots are natural consequence.

- hawski 9y agoIf it runs as root you have much more to worry about, but that's of course one of the problems.
