Hard-link relationships are only maintained within a SyncIQ policy. If hard links to the same file are replicated by multiple SyncIQ policies to the same target cluster, each SyncIQ policy maintains copies of that file and its links within the policy's path.
Hard links outside of the source base path of a SyncIQ policy cause the DomainMark job to fail on the source cluster. If you have selected the checkbox Prepare Policy for Accelerated Failback Performance, the DomainMark job runs automatically on the source cluster during a failback to the source cluster or in advance of a failback. The failover to the target cluster is not impacted by hard links outside of the source base path.
Note: As a best practice, ensure the source cluster base path does not contain hard links outside of the base path. Otherwise, the DomainMark job fails, and then the failback to the source cluster fails.
