Journal Impact on Recovery

If a logical disk is damaged, data tables with local single after-image journaling might not be recovered beyond the last archived data. On the other hand, data tables with remote single after-image journaling might be recovered to the most recent transaction.

While the risks of cylinder corruption are minimal, a cylinder containing a user table and master journal, or a master index, can become corrupted. If this occurs, local journaling does not offer as much protection as remote journaling.
