With oracle8 is definetly the same for me...what is a backup if not reading blocks from database?
And incremental has to read all datafiles blocks, so the time would be the same, or at least is the same on small sized database using solaris 6 and oracle 8.0.6 Received on Wed Sep 18 2002 - 08:51:42 CDT
