It depends. It is the TSM API (not the normal TSM backup client) that receives the data for rman. It sends the data over the LAN or the SAN to the TSM server depending on how you configure it.

No, you need to configure the TSM API for SAN based backup. Also some configuration on the SAN and TSM server must be done. A SAN backup is also going directly to tape. > 3- RMAN does not affect the Oracle server CPU usage and I/O activity. No, the data has to be written and processed so there is extra CPU usage and lots of extra (read) I/O activity. Stef
