Comment 10 for bug 1434722

I didn't found any suitable way of detecting deleted files with 'Full rsync mode'. Only way would be to either go back and run a --dry-run first or to create hard-links with 'cp -aRl' again. Which both would make it very slow again.

There is already a bug report for rsync about this https://bugzilla.samba.org/show_bug.cgi?id=5263
and a discussion on mailing list https://<email address hidden>/msg25381.html
Hopefully they will add an option to get informed about deleted files some day.
