For Disaster Recovery we want to take our nightly disk backups and stage
them to disk at the DR site.  We would upgrade Netbackup to 6.0 before
implementing the plan. The master server would make the initial
backup, and a media server would do the disk staging.  If there were a
disaster at the Data Center, the media server would be promoted to master.
The catalog is mirrored at the disaster site.

1. Can the media server at the DR site do the disk staging?  The reason to
   use the media server is to pass the data through fiber rather than
   Ethernet.

2. Is a media server required to get disk staging through fiber channel? I
   heard that it was needed for backups through fiber in a SAN. So would
   the same apply for DSSU?

3. Can a media server be promoted to master if the master no longer
   exists?
