Local snapshots are only created on disks using the Apple File System (APFS).

These snapshots are created hourly, stored on the same disk as the original files, and saved for up to 24 hours or until space is needed on the disk. When you use Time Machine, Time Machine also saves local snapshots you can use to recover previous versions of files, even if your backup disk is not attached. When Time Machine is turned on, it automatically backs up your Mac and performs hourly, daily, and weekly backups of your files.
