Hi
We are looking for dirty block tracking feature in qemu/kvm for
implementing more efficient incremental backup. I saw some patches
around it, but from the conversation could not figure out if it is
complete or not. If it is complete, can some one point to the branch /
label from which I can get it.
Could of questions around the feature.
* Does this work with qcow format only ? Or for any format ? Can I
use it with ceph, gluster, etc,,etc.
* How does dirty block tracking to file get affected by snapshots
? One would assume that it would mark all the blocks changed since
tracking begun, irrespective of snapshots pull / rebase....etc. This way
one might copy more blocks than necessary, but is accurate. And this
allows the user to do different snapshot operations irrespective of
backups which is a big thing from users perspective.
Thanks
