There are
two ways to back up recovery data. The BACKUP RECOVERY AREA command backs up
all files that are found in the current and any previous Flash Recovery Areas.
The BACKUP RECOVERY FILES command backs up all recovery files, even if they are
not in the Flash Recovery Area. You gain added protection from loss by using
the latter, which would back up, for example, any mirrored copies of control
files or data files that are not in the Flash Recovery Area.
By default,
backup optimization is in effect for these two commands, even if you have
disabled it using the CONFIGURE command. This means that the only recovery
files that this command backs up are those that are not already backed up. You
can force all files to be backed up by using the FORCE option.
You cannot
specify DEVICE TYPE DISK for either of these commands.
