Success, Failure, SuccessIt means the last Log Sequence Number (LSN) of the first backup does not match the first LSN of the second successful backup.
Note The failure is caused by some problem on the backup application after SQL Server has advanced the backup LSN. In this case, there will be a disconnection between the backup application and the SQL Server Engine. Because of the failure on its end, the backup application would not save the backup contents. But SQL Server assumes that it is done with this backup and moves forward. When the next transaction log backup is requested, the backup will contain information only beyond the advanced LSN but not the lost contents. Then you will receive the message that indicates the problem situation.
