This is a rewrite of:
https://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit
Once this commit merges, the above wiki should point to this kbase
document.
NB: I've intentionally left out the example for pull-based full backups.
I'll tackle it once QMP `x-blockdev-reopen` comes out of experimental
mode in upstream QEMU. Then pull-based can be described for both full
and and differntial backups.
Overall, future documents should cover:
- full backups using both push- and pull-mode
- differential backups using both push- and pull-mode
