I can share my backup experience. The current backup/restore api integration is not optimal for incremental backups. It's ok to read the whole disk if you backup it first time, but you have to read the whole disk each time to find changes for incremental backups. It creates huge disk load.<br>
<br>
For optimal backups it's necessary to keep a list of changed blocks since previous backup.<br>
See <a href="http://wiki.qemu.org/Features/IncrementalBackup" rel="noreferrer" target="_blank">http://wiki.qemu.org/Features/IncrementalBackup</a><br>
<br>
Since it's not implemented in oVirt the best option is to run a backup agent inside VM. Yes, it's not very convenient, but it's necessary yet.<br>
