Re: RMAN backups

Backup times with RMAN are going to vary greatly depending upon the hardware 
and how many blocks need to be backed up. Even a very large database can be 
backed up incrementally if very few blocks have changed since the last 
backup with RMAN.

What might be a better yardstick is backup rate. The fastest RMAN backup 
rate I've seen was published by Amazon a few years back. They attained 2TB / 
hour.
