KVM Forum 2018

As any good sysadmin will tell you, collecting data backups are essential for future recovery needs. But making them more efficient and flexible has been an ongoing quest, involving multiple improvements throughout the virtualization stack. In this talk, Eric Blake will give a demonstration of the newest technique available through the qemu+libvirt stack, which now support the ability to orchestrate online incremental backups where third-party clients can grab just the dirty clusters at their own speed, rather than waiting for qemu to push a full backup image to a destination location.
