We switched our backups from writing to the data domain via NFS to DDBoost and it cut the backup time by about 75%. Everything is managed natively using RMAN (rman views DDBoost as a SBTTAPE interface).

We have been quite happy with it. The extra cpu usage during the backup is offset by the much shorter backup window.
