Yes, this isn't a snapshot at the hypervisor level this is a snapshot below the filesystem. The windows analogy, a bad one but still, is the "previous versions" feature.

Windows VSS is a direct "copy" (by feature, not by implementation) of the Linux LVM system which, in turn, was a copy of the one from AIX.

That makes more sense.

Some systems that have had snapshots for as long as I can remember...Solaris, AIX, BSD, Linux, HP-UX and, at some point later after we had been long mocking it for lacking them, Windows. Mac is not enterprise and might have it, but I have no idea. It did at one point via ZFS but might have reverted and lost that functionality.
