Rob Freeman? I am considering doing an rman to disk backup and recovery solution for a 500G-- grow to 1terabyte database. Monster HP servers ... up t0 16 cpu, upto 10,000 concurrent users This rman would be the secondary recovery solution.... (Timefinder is the first). Anybody know time frames I might be able to restore/backup 500Gig to 1terabyte of database from disk? I will perform it before it goes live but I would like get a ball park idea of restore times before hand so we can determine if it can fit in the SLA requirements. Any parameters to focus on to improve performance other than allocating channels?
