Under normal operation, SyncIQ target directories can be written to only by the SyncIQ job itself – all client writes to any target directory are disabled, this is referred to as a protected replication domain. In a protected replication domain, files cannot be modified, created, deleted, or moved within the target path of a SyncIQ job.
SyncIQ provides built-in recovery to the target cluster with minimal interruption to clients. By default, the RPO (recovery point objective) is to the last completed SyncIQ replication point. Optionally, with the use of SnapshotIQ, multiple recovery points can be made available, as explained in SnapshotIQ and SyncIQ.
Note: SyncIQ Failover and Failback does not replicate cluster configurations such as SMB shares and NFS exports, quotas, snapshots, and networking settings, from the source cluster. PowerScale does copy over UID/GID ID mapping during replication. In the case of failover to the remote cluster, other cluster configurations must be configured manually. An application such as Superna Eyeglass can be used to
