By default, Windows configures virtual memory so that page files are automatically created on volumes as the Operating System determines is best. This Virtual Memory setting is called “Automatically manage paging file size for all drives”.
When this setting is enabled, page files sometimes are created by the Operating System on volumes that are part of DataKeeper mirrors. When this occurs, DataKeeper is not able to perform operations on the volume that are necessary for full protection. This setting needs to be disabled on all systems that have DataKeeper mirrors.
How to disable “Automatically manage paging file size for all drives”
This setting can be found in Control Panel “System” dialog.
First, click the Advanced system settings option:
From the System Properties dialog, choose the Advanced tab and click the Settings button in the Performance section.
Choose the Advanced tab in the Performance Options dialog, and click the Change… button in the Virtual Memory section.
In the Virtual Memory dialog, uncheck the “Automatically manage paging file size for all drives”. Then configure pagefiles so that any DataKeeper-protected volumes have no page file configured.
