I am looking at implementing RMAN at my shop and have had numerous questions about the MTTR of our systems. I am facing a lot of resistance by people who are saying using RMAN will cause our downtown to be a lot longer than normal. On our HR system, for example, we would lay the hot backup files down and roll it forward. If I was to use RMAN with a weekly level 0 and incrementals during the week how much longer would it take to restore?? I do not have any practical experience with RMAN and I need to know this info if I plan on using it.
