Re: RMAN Compression experiences

Thats interesting.  That suggests to me that on a restore, RMAN is
decompressing the data on disk then writing to the destination (which would
take two write operations), but during a backup they are compressing it in
memory then writing to the destination (one write operation).  Or do I
misunderstand the implications?
