Pascale, A lot of this depends on what kind of database you are using....Is this a datawarehouse, etc.... For onbar you need to have a storage manager installed, ADSM, ISM, etc...For ontape all you need to have is a tape drive(or hard disk in dire matters) accessible to the machine. If you want to use On-Archive(.....you are a sadistic SOB :) heh...If the size of the database is easily manageable then in my opinion ontape would be the best choice. For larger instances (20+gig) onbar would be the best application. Each system has it's advantages/disadvantages (ontape, quick and easy...onbar, a bit of setup time, On-Archive---hell) All in all i think onbar is the best choice, provided you have the neccessary components. If you have any questions, feel free to email me at brian_foster@vfc.com. Other considerations include maintainence downtime (If you get any...). User queries, batch jobs...etc... If you have a bad disk, obviously onbar, ontape or any other archive/restore program can't fix it. As long as you are using symbolic links(and have extra disk) just about any&everything can be restored.
