Hi Guys
Any one successfully setup this feature(XtraDB changed page tracking).
We are currently evaluating Percona 5.6 & I cannot use this feature to speed up my incremental backups.
Looks like this feature is broken at least with Percona 5.6.16 & 5.6.17.
A bug was already filed here([url]https://bugs.launchpad.net/percona-server/+bug/1323889[/url])
You can see my findings in the 3rd comment.
Thanks & Regards
Santhi Kishore Balusu
