Does MacOS Support a Snapshot-Style Filesystem? I would like to perform daily snapshots that I can revert to if someone:


downloads Malware  
installs buggy software
etc.


Does such a thing exist?  Is there a roadmap for it?

I have a Fusion drive so that would affect my personal situation but I am just asking the general question.
Apple's new file system, APFS, supports snapshots.  Per their documentation:



APFS is available in 10.12.x (Sierra) as a Developer Preview and as a released product in 10.13.x (High Sierra).

Earlier than Sierra, if you need to make a "point in time" backup, it's best to run Time Machine to ensure a good backup.
