Replicating data between systems

You can replicate data between ONTAP Cloud systems and ONTAP clusters by choosing a one-time data replication, which can help you move data to and from the cloud, or a recurring schedule, which can help with disaster recovery or long-term retention.

About this task

Cloud Manager supports simple, fanout, and cascade data protection configurations:
  • In a simple configuration, replication occurs from volume A to volume B.
  • In a fanout configuration, replication occurs from volume A to multiple destinations, which can be SnapMirror or SnapVault destinations.
    Note: Only one SnapVault relationship is allowed in a fanout configuration.
  • In a cascade configuration, replication occurs from volume A to volume B and from volume B to volume C.

You can configure fanout and cascade configurations in Cloud Manager by setting up multiple data replications between systems. For example, by replicating a volume from system A to system B and then by replicating the same volume from system B to system C.

Steps

  1. On the Working Environments page, select the working environment that contains the source volume, and then drag it to the working environment to which you want to replicate the volume:

  2. If the Source and Destination Peering Setup pages appear, select all of the intercluster LIFs for the cluster peer relationship.
    The intercluster network should be configured so that cluster peers have pair-wise full-mesh connectivity, which means that each pair of clusters in a cluster peer relationship has connectivity among all of their intercluster LIFs.
    These pages appear if an ONTAP cluster that has multiple LIFs is the source or destination.
  3. On the Source Volume Selection page, select the volume that you want to replicate, and then click Continue.
  4. On the Destination Volume page, specify the destination volume name, choose an underlying disk type, and then specify the maximum rate (in kilobytes per second) at which data can be transferred (for example, 10240 KB/s).
    Note the following:
    • You should limit the transfer rate. An unlimited rate might negatively impact the performance of other applications and it might impact your Internet performance, if you use a VPN connection and replicate data between on-premises ONTAP clusters and ONTAP Cloud systems.
    • If the destination is an ONTAP cluster, you must also specify the destination SVM and aggregate.
    • If ONTAP Cloud is the destination, you can also choose a specific aggregate for the destination volume when you click Advanced options.
  5. On the Replication Policy page, choose one of the default policies or click Additional Policies, and then select one of the advanced policies.
    If you choose a custom SnapVault policy, the labels associated with the policy must match the labels of the Snapshot copies on the source volume.
  6. On the Schedule page, choose a one-time copy or a recurring schedule.
    Several default schedules are available. If you want a different schedule, you must create a new schedule on the destination cluster using System Manager.
  7. On the Review page, review your selections, and then click Go.

Result

Cloud Manager starts the data replication process. You can view details about the replication in the Replication Status page.
