I have site A connected to site B and site A connected to site C and there is not a connection from site B to C. Site A is production site B is a vendor provided DR site currently backing up to. And site C will be our new DR site we want to backup to B and C until we test C then site B will go away.

Or all three? And when you say you want to copy from site A to sites B and C, may we assume you are talking about copying the same data from site A to the other sites? Or different data (part of site A to B, and another part of A to C)? I think I understand why different might be useful, at least in rare cases. (You might want to have split responsibility for DR in some cases -- aligned with LPARs, functional areas, or whatever. It's a little strange/unusual perhaps, but that's OK.) If the same data, what is the disaster recovery scenario you're trying to solve? If site A fails and B recovers, then what is C for? (I'm assuming B and C are not connected. Or are they?) Are you thinking of protecting against a simultaneous failure of site A plus either B or C (but not both)? - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Based in Tokyo, Serving IBM Japan / Asia-Pacific E-Mail: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
