When using SnapMirror SVM replication, the cloud tiering policy on the destination volume must match the source if tiering is to be preserved. The only supported tiering policy in this context is snapshot-only, which moves cold Snapshot blocks to cloud tier. This ensures compatibility during replication.

Autonomous Ransomware Protection (ARP) operates in two modes:Learning mode: ARP observes and learns baseline workload behaviors to distinguish between normal and abnormal activity.Active mode: ARP actively monitors and can automatically respond to ransomware-like behavior by alerting or taking protective actions.

SnapMirror replication is driven by labels that match between the snapshot policy on the source volume and the SnapMirror policy. If the snapshot policy on the source does not include the correct SnapMirror label, SnapMirror will not recognize which snapshots to replicate, resulting in no transfers.

Autonomous Ransomware Protection (ARP) is a native NetApp ONTAP feature that uses machine learning to monitor and analyze file activity patterns. It detects anomalies such as sudden spikes in file changes — typical of ransomware behavior — and automatically alerts or blocks access to limit potential damage.

To retain multiple yearly Snapshot copies only on the SnapMirror destination, you must apply a Snapshot policy on the secondary volume. This avoids consuming space on the source volume, as these Snapshots are created and retained independently on the destination.

NetApp ONTAP supports two types of Compliance Clocks for write once, read many (WORM) and SnapLock compliance:The system Compliance Clock is maintained at the cluster level and ensures tamperproof retention.The volume Compliance Clock is specific to SnapLock volumes and is used to enforce retention periods at the volume level.

Setting snapdir-access to false prevents users accessing the CIFS/NFS share from viewing or deleting Snapshot copies via the .snapshot directory. This secures the Snapshot restore mechanism from being exposed or tampered with in case of another attack through file shares.

Although the SnapMirror policy includes rules for retaining Snapshot copies, the ability to make them tamper-proof (i.e., locked) depends on enabling snapshot locking on the destination volume. You must explicitly run:volume modify -volume -snapshot-locking-enabled trueWithout this setting, SnapMirror-created Snapshot copies can still be deleted manually. Enabling snapshot-locking ensures that retention rules (like the 5-day daily rule in your policy) are enforced and Snapshots are immutable.

To separate traffic for different cluster peering relationships on the same cluster (Cluster1), you need to configure IPspaces. IPspaces allow multiple logical network domains within a single ONTAP cluster, ensuring that peering traffic to Cluster2 and Cluster3 remains isolated.

Each node in a NetApp cluster must have at least one Intercluster LIF to participate in SnapMirror replication. Therefore, for a six-node cluster (primary), you need six LIFs, and for a two-node cluster (secondary), you need two LIFs — one per node.

In SnapCenter, to ensure application-consistent backups for Oracle, SQL, and Exchange, you must create a consistency group for each application. These groups organize the correct resource groups (which define the backup scope) and ensure all related components are captured in a consistent state during the backup.
