Methods, systems, and configured storage media are provided for flexible data mirroring. In particular, the invention provides local-remote role reversal (1506), implementation of hot standby server status through a "media not ready" signal (1508), several alternate buffer contents and buffering schemes, transactioning (1516), many-to-one mirroring through use of "virtual" remote mirroring units (1520), identification (1522) of frequently accessed data withbout application-specific knowledge but based instead on an application's logged and analyzed behavior, and use (1526) of the secondary server in a non-authoritative manner. |
