Configuration Check
Chapter 234
IMPORTANT If the configuration check is disabled for an instant recovery, you will lose
the data that does not belong to a component, but resides on the same
volume as the component. Disable configuration check only if instant
recovery cannot be performed with an enabled configuration check and
only if you are sure that this will not result in a loss of data during the
instant recovery.
The configuration check should not be disabled except for the cases when
instant recovery cannot be performed with an enabled configuration
check. Due to the specific behavior, some writers (not applicable to the
MSDE Writer and Microsoft Exchange Server writers) may create
temporary files on components volumes during backup and instant
recovery causing the check failure. In such cases, instant recovery will
not be possible.
