Selecting Event Viewer Log Files to Back Up
Use the Log File Backup page to optionally preserve Windows Event Viewer log files from the
Production Side of your system during the Active Upgrade process.
When you commit an upgrade, the system reestablishes the RDR mirrors of any system disks by
overwriting the Production Side disks (which contain the old version of your software) with the
newer Upgrade Side disks (which contain your newly-upgraded software). Because the event log
files on the Production Side are lost during this process, you might want to preserve them for future
reference. These log files will contain the only record of log messages your live applications
generated while the system was split.
The Log File Backup page allows you to select from all event logs available in the Windows Event
Viewer, including user-created logs.
IMPORTANT:
For information about creating a Custom Action that preserves other files from the Production Side
system disk, see "Configuring Custom Actions" on page 5-138.
