Comment 6 for bug 1398994

TRUNCATE is equivalent to DROP + CREATE. Which means to fix this bug we should filter tablespace creation operations when preparing a partial backup based on the original pattern which was used to create the partial backup.

A related problem is when during a partial backup a regular CREATE TABLE is executed for a InnoDB table which does not match the filters. It would still be present in the resulting backup after prepare, but that's not what users would expect.
