Select the directory where the rewind log file should be stored (this is only applicable when the system is a mirror target). There should be adequate space in this location to store the desired amount of history in the log1. The log cannot be located on a mirror or shared disk and should, for optimal performance, be located on a separate physical disk from any mirrors. An empty setting disables rewind logging.
Note: The mirror must be paused and restarted before any setting changes will take effect.
1The log file contains a copy of every disk block that is written to the mirrored disk so the log file can grow larger than the mirrored disk itself if the same disk blocks are written multiple times, as is the case when a file is modified or appended to.
