Regarding Online Redo log backup

Dear all,

I am running "Whole database online + Redo log backup" in production server which running successfully with return code 0000.

Is this backup takes online redo log file also?????? because in backup log i didn't see any directory like .../../orilog A, .../../orilog B etc which contains online redo log file.

Without this online redo log backup i don't thing we can do point to point recovery.

I am beginner for oracle so please clear this doubt.

thanks,

Tarun
