No idea if this could work, but how about creating a pipe (mknod) start a process reading the pipe (e.g. wc to count bytes), then backup to the pipe.

Dear all,Out of curiosity, is there a way to simulate a rman backup run ? The purpose will be to simulate a backup execution without actually writing any files just to observe how big a compressed backup will be.Most probably officially this is not supported but anyone has any crazy idea how to achieve this? :)Thank you.
