Use this library to backup your MySQL Database from your Java code. This library only backs up the data, not the database structure(Future Releases). So when restoring the backup file, you must ensure that the database is created and fully functional.
Replicross synchronizes two databases of similar structure. Rules written in an XML/EMF model describe how data must be updated from one base to the other. Another functionality is to propagate incrementally the structure of one database to the other.
Storesim simulates creation of large amount of random files. Directory structure created is similar to what is done in very large file repositories: based on hashdirs (found in mailservers, NFS servers, files servers, image databases...)
