For Xtrabackup I have such a test plan, tried to reach the expected results, everybody to help analyze the scheme is reasonable, thank

Part1 for db to do a full backup
Part2 to create a test table, insert test data
Part3 incremental backup
Part4 delete test table
Part5 incremental backup again
Part6 to restore the original state
Part7 restore the first raised for
Part8 restore the second rights for


Part7 and part8 do incremental recovery is an error: the target seems no metadata,
