Yes, RMAN backup compression is typically quite good.  I've had a 2.4 TB
database backed up into <700 MB.  The downside is that restoring the
compressed backup set can take a lot more time, which is particularly
irritating if you only need to restore a single datafile.

Of course, you should test the restore to prove that it was successful.
