Source and target cluster snapshots use SnapshotIQ snapshots. Source cluster snapshots are enabled by default, as required by the dataset creation policy. Target cluster snapshots are created if the copy-create-dataset-on-target option is set to true for a copy or repeat-copy policy. You can view the snapshots on the source and target clusters under isi snapshot list and isi dm datasets list. Manage snapshots by using the dataset retention period and reserve options, as explained in Dataset creation policy and Replication policies. Alternatively, run an expiration policy, as described in Expiration policy.
