There is reaally a confusion there. At one place it says that all the
changes to that datafile or tablespace in backup mode goto redo logs
that is why more redo is generated. If some data in a block is chanaged
then instead of that change going to the redo the whole block goes to
redo. The question is does oracle stops writing to datafiles in backup
mode and if it does then how these changes are refelected in the
datafile and the other part is if it keeps on writing to the datafile in
backup mode then that file can go out of sync with the backed up file.
All thoughts are welcome
