Seems like if you just tar everything up without querying the database for the file locations, you stand a chance of missing files. You are relying on the good will of all involved to put new datafiles under the mountpoints you are backing up. If someone makes a mistake and puts a new datafile in a different place, it can result in that file not getting backed up. All backup scripts, hot and cold, should be obtaining the file locations from the database instance. You are not really saving anything by avoiding "oracle commands."

What? you haven't recovered past resetlogs before?
