* This class tests online backup with various types of paths.
* 1 ) backup path is same as a database directory. This should fail backup
* can not be made onto a database directory. (DERBY-304 bug).
* 2 ) backup path is a sub directory in the database.
* 3 ) Redo backup with same path as in second case.
* 4 ) backup path is absolute path.
* If the path refers to some sub directory inside a database, backup
* will succeed because there is no easy way to catch this weird case,
* especially if the backup path refers to another database directory.
