Asynchronous source-based replication

  • SyncIQ is an asynchronous remote replication tool. It differs from synchronous remote replication tools where the writes to the local storage system are not acknowledged back to the client until those writes are committed to the remote storage system. SyncIQ asynchronous replication allows the cluster to respond quickly to client file system requests while replication jobs run in the background, per policy settings.

    To protect distributed workflow data, SyncIQ prevents changes on target directories. If the workflow requires writable targets, the SyncIQ source/target association must be broken before writing data to a target directory, and any subsequent reactivation of the synchronize association requires a full synchronization.

    Note: Practice extreme caution before breaking a policy between a source and target cluster or allowing writes on a target cluster. First ensure that you understand the repercussions. For more information, see Impacts of modifying SyncIQ policies and Allow-writes compared to break association.
