You have to do backups of the entire database. you cannot backup a single table.
Also you should do periodic backups of:
- transaction log in sybase/MS-SQL
- archive logs in oracle
backing up the AJF is not a way to recover from the production problem.
As we discuss about online job processing, it would be better to use mirroring of ctm database in case of primary is broken. This is the best way to HA.
