038 * CMS_BACKUP_PROJECTRESOURCES
039 * CMS_BACKUP_PROPERTIES

041 * CMS_BACKUP_RESOURCES
042 * CMS_BACKUP_STRUCTURE
043 *
044 * The tables CMS_HISTORY_PRINCIPALS and CMS_HISTORY_PROJECTS are created in other classes.
045 *
046 * CMS_HISTORY_PRINCIPALS is a completely new table and is therefor handled by its own class.
047 *
048 * CMS_HISTORY_PROJECTS needs extra conversion beyond the execution of SQL statements and is
049 * also handled by a special class.
