Failover Cluster incremental backup is not performed.
ActiveImage Protector creates a $AIPMAP for tracking the bitmap information. This file holds the bitmap information and machine ID.
If this information is not available, a reconcile or full backup is performed.
There are scenarios where a reconcile or full backup has occurred.
1) Failover occurs.
2) Machine ID saved in the AIPMAP will change.
3) If reconcile function is disabled, the base backup is done.
If the reconcile feature is enabled, reconcile backup is done.
4) Incremental backup is performed a second time.
This is the expected behavior.
The cluster in which this occurs.
