We plan to host the Master and one media server( out of 1 Master and 3 Media servers- whereas Master itself is Media server) in New Data Center while keeping the other media servers in Old Data Center. Backups in Old Data Center will be performed by the media servers there, and send catalog data across the WAN to New Data Center (45ms network response time). Master and media servers in New Data Center will not be configured to talk to any tape drives or participate in backups (that are in Old Data Center).
Please let me know your suggestions on how this can be achieved.
Are you using NBU appliances?
What version of NBU are you using or planning on using?
Are you talking about using AIR for replication between New and Old data center? More details will help.
