It is all dependent on your situation. If I can use SAN replication instead of data guard or dbvisit, I’m going to use it. It is one less thing I have to worry about.

There is no such thing as "better" or "worse". There is only "it is a better fit to my situation and budget". There are several solutions:

  • Data Guard
  • DbVisit
  • SAN replication
  • Snapshot based discrete backups, like SnapVault by NetApp.
  • Database replication, like GG or SharePlex.

Corporate giants like Citigroup, Exxon Mobile or Walmart will probably chose different solution than some smaller companies. Fortunately, I am not a DBA any more, so I don't have to chose the solution any more. That is also the reason why this debate will never reach any meaningful end.
