wikipedia:qcow2[1] is a file format for disk image files used by QEMU. qcow2 support AES and multiple snapshots.
A qcow2 image file is organized in units of constant size, which are called (host) clusters. A cluster is the unit in which all allocations are done, both for actual guest data and for image metadata.[2]
qcow2 internal snapshots are best avoided in favour of extenal snapshots. [3]
