Disk Mirroring.

This article is a stub. You can improve NDWiki by expanding it.

Description

Enhance security against disk failures by automatically duplicating data stores on selected disk(s). Allow online backup of databases to be taken.

Reason for new version

In the L-version of SINTRAN III, the disk mirroring code is merged with the SINTRAN III code. This means that SINTRAN patching is no longer a part of the installation procedure. Further, all messages are routed through the new SINTRAN III error handling, the ERS watchdog. The FTX error logger is thus no longer a prerequisite.
