    [$] Changed-block tracking and differential backups in QEMU
    The block layer of QEMU, the open-source
    machine emulator and virtualizer, forms the backbone of many storage
    virtualization features    : the QEMU Copy-On-Write (QCOW2) disk-image file format,
    disk image chains, point-in-time snapshots, backups, and more. At the
    recently concluded 2020 KVM Forum
    virtual event, Eric Blake gave a talk
    on the current work in QEMU and libvirt
    to make differential backups more powerful. As the name implies,
    "differential backups" address the efficiency problems of full disk
    backups: space usage and speed of backup creation.
