Livebackup - A full backup solution for making full and incremental disk backups of a running VM

Livebackup provides the ability for an administrator or a management server to use a livebackup_client program to connect to the qemu process and copy the disk blocks that were modified since the last backup was taken.

Overview

The goal of this project is to add the ability to do full and incremental disk backups of a running VM. These backups will be transferred over a TCP connection to a backup server, and the virtual disk images will be reconstituted there. This project does not transfer the memory contents of the running VM, or the device states of emulated devices, i.e. livebackup is not VM suspend.
