+New snapshots are created for example when [upgrading](./upgrade) the machine with a new OS image.  
+The `loopdevice` snapshotter will unpack new images on a `ext4` filesystem, while the `btrfs` snapshotter will make use of the underlying [btrfs snapshots](https://archive.kernel.org/oldwiki/btrfs.wiki.kernel.org/index.php/SysadminGuide.html#Snapshots) functionality, greatly reducing the amount of disk space needed to store multiple snapshots.
