sbt tape compression independently can be used on the TAPE side. Oracle recommends You should not use both tape compression provided by the media manager _and_ binary compression provided by RMAN. If the media manager compression is efficient, then it is usually the better choice. Using RMAN-compressed backup sets can be an effective alternative to reduce bandwidth used to move uncompressed backup sets over a network to the media manager, if the CPU overhead required to compress the data in RMAN is acceptable.
