A "typical" desktop user doesn't really use most of their typically 1TB hard disk. It could be years before it needs to overwrite any existing data.

LogFS returns

If you have a hard disk, I would suggest you try btrfs instead. It was designed for spinning rust, logfs was designed for leaky electron traps.

But if you can guarantee that the total amount of data ever written does not exceed the size of your medium, historical data would indeed stay around. You cannot access deleted data through the filesystem code itself, but you could write a dump tool that goes back in time.

How that dump tool would behave once the garbage collector has to reuse old segments is another question. ;)
