And to make sure that you have storage space when you need it, snapshots are stored only on disks that have plenty of free space. When storage space gets low,\u00a0additional snapshots are deleted, starting with the oldest.\u00a0That&#8217;s why Finder and Get Info windows don&#8217;t include local snapshots in their calculations of the storage space available on a disk.<\/p>\n<p>I think the concept is ok, however I don&#8217;t want \/ need it. There is currently no option to turn this &#8216;feature&#8217; off.
