Re: RMAN Compession (Again)

RMAN doesn't have any gzip-like compression utility built into it. So you'll have to use an external routine to do this if you want. RMAN does let you run an outside utility with the HOST command, right from your RMAN script. So you can use that. But heed Sybrand's warning that the compressed file won't be able to be used by RMAN until you manually uncompress it.
