Create a replication relationship for an FSx for ONTAP file system in NetApp Workload Factory to avoid data loss in case of an unforeseen disaster. Replication is supported between two FSx for ONTAP file systems, and between Cloud Volumes ONTAP or an on-premises ONTAP system and an FSx for ONTAP file system.

About this task

Replication adds protection against data loss if the region where your data resides experiences a disaster.

This operation creates a replication relationship for source volumes in an FSx for ONTAP file system, on-premises ONTAP system, or Cloud Volumes ONTAP system.

Replicated volumes in the target file system are data protection (DP) volumes and follow the naming format: {OriginalVolumeName}_copy.

When you replicate a source volume with immutable files, the target volume and file system stay locked until the retention period of the immutable files in the source volume ends. The immutable files feature is available when you create a volume for an FSx for ONTAP file system.

Note

  • Replication isn't supported for block volumes using iSCSI or NVMe protocols.

  • You can replicate one source (read/write) volume or one data protection (DP) volume. Cascading replication is supported, but a third hop isn't. Learn more about cascading replication.
Before you begin

Consider the following before you begin.

  • You must have one FSx for ONTAP file system to use for the target in the replication relationship.

  • The FSx for ONTAP file system you use for the replication relationship must have an associated link. Learn how to associate an existing link or to create and associate a new link. After you associate the link, return to this operation.

  • For replication from an on-premises ONTAP system to an FSx for ONTAP file system, make sure you have discovered the on-premises ONTAP system.

Follow these steps to replicate specific or all volumes in a file system.

Steps

  1. Log in using one of the console experiences.

  2. Select the menu The hamburger menu icon is used to navigate to workloads like storage and then select Storage.

  3. From the Storage menu, select FSx for ONTAP.

  4. From FSx for ONTAP, select the actions menu of the file system that contains the volume(s) to replicate and then select Manage.

  5. Either replicate all volumes in a file system or replicate select volumes.

    • To replicate all volumes in a file system: From the file system overview, select Replicate data.

    • To replicate select volumes: From the file system overview, select the Volumes tab.

      In the Volumes table, select one or more volumes and then select Replicate data.

  6. On the Replicate data page, under Replication target, provide the following:

    1. Use case: Select one of the following use cases for the replication. Depending on the selected use case, Workload Factory fills in the form with recommended values in accordance with best practices. You can accept the recommended values or make changes as you complete the form.

      • Migration: transfers your data to the target FSx for ONTAP file system

      • Hot disaster recovery: ensures high availability and rapid disaster recovery for critical workloads

      • Cold or archive disaster recovery:

        • Cold disaster recovery: uses longer recovery time objectives (RTO) and recovery point objects (RPO) to lower costs

        • Archive: replicates data for long-term storage and compliance

      • Other

        Additionally, the use case selection determines the replication policy, or SnapMirror policy (ONTAP). The terms used to describe replication policies come from ONTAP 9 documentation.

        • For migration and other, the replication policy is called MirrorAllSnapshots. MirrorAllSnapshots is an asynchronous policy for mirroring all snapshots and the latest active file system.

        • For hot, cold, or archive disaster recovery, the replication policy is called MirrorAndVault. MirrorAndVault is an asynchronous and vault policy for mirroring the latest active file system and daily and weekly snapshots.

          For all use cases, if you enable snapshots for long-term retention, the default replication policy is MirrorAndVault.

    2. FSx for ONTAP file system: Select credentials, region, and FSx for ONTAP file system name for the target FSx for ONTAP file system.

    3. Storage VM name: Select the storage VM from the dropdown menu. The storage VM you select is the target for all selected volumes in this replication relationship.

    4. Volume name: The target volume name is generated automatically with the following format {OriginalVolumeName}_copy. You can use the auto-generated volume name or enter another volume name.

    5. Tiering policy: Select the tiering policy for the data stored in the target volume. The tiering policy defaults to the recommended tiering policy for the use case you selected.

      Balanced (Auto) is the default tiering policy when creating a volume using the Workload Factory console. For more information about volume tiering policies, refer to Volume storage capacity in AWS FSx for NetApp ONTAP documentation. Note that Workload factory uses use-case based names in the Workload Factory console for tiering policies and includes FSx for ONTAP tiering policy names in parentheses.

      If you selected the migration use case, Workload Factory automatically selects to copy the tiering policy of source volume to the target volume. You can deselect to copy the tiering policy and select a tiering policy which applies to the volume selected for replication.

    6. Max transfer rate: Select Limited and enter the max transfer limit in MB/s. Alternatively, select Unlimited.

      Without a limit, network and application performance may decline. Alternatively, we recommend an unlimited transfer rate for FSx for ONTAP file systems for critical workloads, for example, those that are used primarily for disaster recovery.

  7. Under Replication settings, provide the following:

    1. Replication interval: Select the frequency that snapshots are transferred from the source volume to the target volume.

    2. Long-term retention: Optionally, enable snapshots for long-term retention. Long-term retention enables business services to continue operating even through a complete site failure, supporting applications to fail over transparently using a secondary copy.

      Replications without long-term retention use the MirrorAllSnapshots policy. Enabling long-term retention assigns the MirrorAndVault policy to the replication.

      If you enable long-term retention, then select an existing policy or create a new policy to define the snapshots to replicate and the number to retain.

      Note Matching source and target labels are required for long-term retention. If desired, Workload factory can create missing labels for you.

      • Choose an existing policy: select an existing policy from the dropdown menu.

      • Create a new policy: enter a policy name.

    3. Immutable snapshots: Optional. Select Enable immutable snapshots to prevent snapshots taken in this policy from being deleted during the retention period.

      • Set the Retention period in number of hours, days, months, or years.

      • Snapshot policies: In the table, select the snapshot policy frequency and the number of copies to retain. You can select more than one snapshot policy.

    4. S3 access point: Optionally, attach an S3 access point to access FSx for ONTAP file system data residing on NFS or SMB/CIFS volumes via AWS S3 APIs. Only the file access type is supported. Providing the following details:

      • S3 access point name: Enter the name of the S3 access point.

      • User: Select an existing user with access to the volume or create a new user.

      • User type: Select UNIX or Windows as the user type.

      • Network configuration: Select Internet or Virtual private cloud (VPC). The type of network you choose determines whether the access point is accessible from the internet or restricted to a specific VPC.

      • Enable metadata: Enabling metadata creates an S3 table containing all objects accessible by the S3 access point, which you can use for auditing, governance, automatic, analysis, and optimization. Enabling metadata incurs additional AWS costs. Refer to Amazon S3 pricing documentation for more information.

    5. S3 access point tags: Optionally, you can add up to 50 tags.

  1. Select Create.

Result

The replication relationship appears in the Replication relationships tab in the target FSx for ONTAP file system.
