OADP 1.3.0 release notes

The OpenShift API for Data Protection (OADP) 1.3.0 release notes lists new features, resolved issues and bugs, and known issues.

New features

Velero built-in DataMover

OADP 1.3 includes a built-in Data Mover that you can use to move Container Storage Interface (CSI) volume snapshots to a remote object store. The built-in Data Mover allows you to restore stateful applications from the remote object store if a failure, accidental deletion, or corruption of the cluster occurs. It uses Kopia as the uploader mechanism to read the snapshot data and to write to the Unified Repository.

Velero built-in DataMover is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.

Backing up applications with File System Backup: Kopia or Restic

Velero’s File System Backup (FSB) supports two backup libraries: the Restic path and the Kopia path.

Velero allows users to select between the two paths.

For backup, specify the path during the installation through the uploader-type flag. The valid value is either restic or kopia. This field defaults to kopia if the value is not specified. The selection cannot be changed after the installation.

GCP Cloud authentication

Google Cloud Platform (GCP) authentication enables you to use short-lived Google credentials.

GCP with Workload Identity Federation enables you to use Identity and Access Management (IAM) to grant external identities IAM roles, including the ability to impersonate service accounts. This eliminates the maintenance and security risks associated with service account keys.

AWS ROSA STS authentication

You can use OpenShift API for Data Protection (OADP) with Red Hat OpenShift Service on AWS (ROSA) clusters to backup and restore application data.

ROSA provides seamless integration with a wide range of AWS compute, database, analytics, machine learning, networking, mobile, and other services to speed up the building and delivering of differentiating experiences to your customers.

You can subscribe to the service directly from your AWS account.

After the clusters are created, you can operate your clusters by using the OpenShift web console. The ROSA service also uses OpenShift APIs and command-line interface (CLI) tools.

Resolved issues

ACM applications were removed and re-created on managed clusters after restore

Applications on managed clusters were deleted and re-created upon restore activation. OpenShift API for Data Protection (OADP 1.2) backup and restore process is faster than the older versions. The OADP performance change caused this behavior when restoring ACM resources. Therefore, some resources were restored before other resources, which caused the removal of the applications from managed clusters. OADP-2686

Restic restore was partially failing due to Pod Security standard

During interoperability testing, OpenShift Container Platform 4.14 had the pod Security mode set to enforce, which caused the pod to be denied. This was caused due to the restore order. The pod was getting created before the security context constraints (SCC) resource, since the pod violated the podSecurity standard, it denied the pod. When setting the restore priority field on the Velero server, restore is successful. OADP-2688

Possible pod volume backup failure if Velero is installed in several namespaces

There was a regresssion in Pod Volume Backup (PVB) functionality when Velero was installed in several namespaces. The PVB controller was not properly limiting itself to PVBs in its own namespace. OADP-2308

OADP Velero plugins returning "received EOF, stopping recv loop" message

In OADP, Velero plugins were started as separate processes. When the Velero operation completes, either successfully or not, they exit. Therefore, if you see a received EOF, stopping recv loop messages in debug logs, it does not mean an error occurred, it means that a plugin operation has completed. OADP-2176

CVE-2023-39325 Multiple HTTP/2 enabled web servers are vulnerable to a DDoS attack (Rapid Reset Attack)

In previous releases of OADP, the HTTP/2 protocol was susceptible to a denial of service attack because request cancellation could reset multiple streams quickly. The server had to set up and tear down the streams while not hitting any server-side limit for the maximum number of active streams per connection. This resulted in a denial of service due to server resource consumption.

For more information, see CVE-2023-39325 (Rapid Reset Attack)

For a complete list of all issues resolved in this release, see the list of OADP 1.3.0 resolved issues in Jira.

Known issues

CSI plugin errors on nil pointer when csiSnapshotTimeout is set to a short duration

The CSI plugin errors on nil pointer when csiSnapshotTimeout is set to a short duration. Sometimes it succeeds to complete the snapshot within a short duration, but often it panics with the backup PartiallyFailed with the following error: plugin panicked: runtime error: invalid memory address or nil pointer dereference.

Backup is marked as PartiallyFailed when volumeSnapshotContent CR has an error

If any of the VolumeSnapshotContent CRs have an error related to removing the VolumeSnapshotBeingCreated annotation, it moves the backup to the WaitingForPluginOperationsPartiallyFailed phase. OADP-2871

Performance issues when restoring 30,000 resources for the first time

When restoring 30,000 resources for the first time, without an existing-resource-policy, it takes twice as long to restore them, than it takes during the second and third try with an existing-resource-policy set to update. OADP-3071

Post restore hooks might start running before Datadownload operation has released the related PV

Due to the asynchronous nature of the Data Mover operation, a post-hook might be attempted before the related pods persistent volumes (PVs) are released by the Data Mover persistent volume claim (PVC).

GCP-Workload Identity Federation VSL backup PartiallyFailed

VSL backup PartiallyFailed when GCP workload identity is configured on GCP.

For a complete list of all known issues in this release, see the list of OADP 1.3.0 known issues in Jira.

Upgrade notes

Always upgrade to the next minor version. Do not skip versions. To update to a later version, upgrade only one channel at a time. For example, to upgrade from OpenShift API for Data Protection (OADP) 1.1 to 1.3, upgrade first to 1.2, and then to 1.3.

Changes from OADP 1.2 to 1.3

The Velero server has been updated from version 1.11 to 1.12.

OpenShift API for Data Protection (OADP) 1.3 uses the Velero built-in Data Mover instead of the VolumeSnapshotMover (VSM) or the Volsync Data Mover.

This changes the following:

  • The spec.features.dataMover field and the VSM plugin are not compatible with OADP 1.3, and you must remove the configuration from the DataProtectionApplication (DPA) configuration.

  • The Volsync Operator is no longer required for Data Mover functionality, and you can remove it.

  • The custom resource definitions volumesnapshotbackups.datamover.oadp.openshift.io and volumesnapshotrestores.datamover.oadp.openshift.io are no longer required, and you can remove them.

  • The secrets used for the OADP-1.2 Data Mover are no longer required, and you can remove them.

OADP 1.3 supports Kopia, which is an alternative file system backup tool to Restic.

  • To employ Kopia, use the new spec.configuration.nodeAgent field as shown in the following example:

    Example
    spec:
      configuration:
        nodeAgent:
          enable: true
          uploaderType: kopia
    # ...
  • The spec.configuration.restic field is deprecated in OADP 1.3 and will be removed in a future version of OADP. To avoid seeing deprecation warnings, remove the restic key and its values, and use the following new syntax:

    Example
    spec:
      configuration:
        nodeAgent:
          enable: true
          uploaderType: restic
    # ...

In OADP 1.4, the kopia will become the default uploaderType value.

Upgrading steps

Upgrading from OADP 1.2 Technology Preview Data Mover

OpenShift API for Data Protection (OADP) 1.2 Data Mover backups cannot be restored with OADP 1.3. To prevent a gap in the data protection of your applications, complete the following steps before upgrading to OADP 1.3:

Procedure
  1. If your cluster backups are sufficient and Container Storage Interface (CSI) storage is available, back up the applications with a CSI backup.

  2. If you require off cluster backups:

    1. Back up the applications with a file system backup that uses the --default-volumes-to-fs-backup=true or backup.spec.defaultVolumesToFsBackup options.

    2. Back up the applications with your object storage plugins, for example, velero-plugin-for-aws.

To restore OADP 1.2 Data Mover backup, you must uninstall OADP, and install and configure OADP 1.2.

Backing up the DPA configuration

You must back up your current DataProtectionApplication (DPA) configuration.

Procedure
  • Save your current DPA configuration by running the following command:

    Example
    $ oc get dpa -n openshift-adp -o yaml > dpa.orig.backup

Upgrading the OADP Operator

Use the following sequence when upgrading the OpenShift API for Data Protection (OADP) Operator.

Procedure
  1. Change your subscription channel for the OADP Operator from stable-1.2 to stable-1.3.

  2. Allow time for the Operator and containers to update and restart.

Additional resources

Converting DPA to the new version

If you need to move backups off cluster with the Data Mover, reconfigure the DataProtectionApplication (DPA) manifest as follows.

Procedure
  1. Click OperatorsInstalled Operators and select the OADP Operator.

  2. In the Provided APIs section, click View more.

  3. Click Create instance in the DataProtectionApplication box.

  4. Click YAML View to display the current DPA parameters.

    Example current DPA
    spec:
      configuration:
        features:
          dataMover:
          enable: true
          credentialName: dm-credentials
        velero:
          defaultPlugins:
          - vsm
          - csi
          - openshift
    # ...
  5. Update the DPA parameters:

    • Remove the features.dataMover key and values from the DPA.

    • Remove the VolumeSnapshotMover (VSM) plugin.

    • Add the nodeAgent key and values.

      Example updated DPA
      spec:
        configuration:
          nodeAgent:
            enable: true
            uploaderType: kopia
          velero:
            defaultPlugins:
            - csi
            - openshift
      # ...
  6. Wait for the DPA to reconcile successfully.

OADP 1.2.2 release notes

New features

There are no new features in the release of OpenShift API for Data Protection (OADP) 1.2.2.

Resolved issues

The following highlighted issues are resolved in OADP 1.2.2:

Restic restore partially failed due to a Pod Security standard

In previous releases of OADP 1.2, OpenShift Container Platform 4.14 enforced a pod security admission (PSA) policy that hindered the readiness of pods during a Restic restore process.

This issue has been resolved in the release of OADP 1.2.2, and also OADP 1.1.6. Therefore, it is recommended that users upgrade to these releases.

Backup of an app with internal images partially failed with plugin panicked error

In previous releases of OADP 1.2, the backup of an application with internal images partially failed with plugin panicked error returned. The backup partially fails with this error in the Velero logs:

time="2022-11-23T15:40:46Z" level=info msg="1 errors encountered backup up item" backup=openshift-adp/django-persistent-67a5b83d-6b44-11ed-9cba-902e163f806c logSource="/remote-source/velero/app/pkg/backup/backup.go:413" name=django-psql-persistent
time="2022-11-23T15:40:46Z" level=error msg="Error backing up item" backup=openshift-adp/django-persistent-67a5b83d-6b44-11ed-9cba-902e163f8

This issue has been resolved in OADP 1.2.2. (OADP-1057).

ACM cluster restore was not functioning as expected due to restore order

In previous releases of OADP 1.2, ACM cluster restore was not functioning as expected due to restore order. ACM applications were removed and re-created on managed clusters after restore activation. (OADP-2505)

VM’s using filesystemOverhead failed when backing up and restoring due to volume size mismatch

In previous releases of OADP 1.2, due to storage provider implementation choices, whenever there was a difference between the application persistent volume claims (PVCs) storage request and the snapshot size of the same PVC, VM’s using filesystemOverhead failed when backing up and restoring. This issue has been resolved in the Data Mover of OADP 1.2.2. (OADP-2144)

OADP did not contain an option to set VolSync replication source prune interval

In previous releases of OADP 1.2, there was no option to set the VolSync replication source pruneInterval. (OADP-2052)

Possible pod volume backup failure if Velero was installed in multiple namespaces

In previous releases of OADP 1.2, there was a possibility of pod volume backup failure if Velero was installed in multiple namespaces. (OADP-2409)

Backup Storage Locations moved to unavailable phase when VSL uses custom secret

In previous releases of OADP 1.2, Backup Storage Locations moved to unavailable phase when Volume Snapshot Location used custom secret. (OADP-1737)

For a complete list of all issues resolved in the release of OADP 1.2.2, see the list of OADP 1.2.2 resolved issues in Jira.

Known issues

The following issues have been highlighted as known issues in the release of OADP 1.2.2:

Must-gather command fails to remove ClusterRoleBinding resources

The oc adm must-gather command fails to remove ClusterRoleBinding resources, which are left on cluster due to admission webhook. Therefore, requests for the removal of the ClusterRoleBinding resources are denied. (OADP-27730)

admission webhook "clusterrolebindings-validation.managed.openshift.io" denied the request: Deleting ClusterRoleBinding must-gather-p7vwj is not allowed

Changes from OADP 1.1 to 1.2

The Velero server was updated from version 1.9 to 1.11.

In OADP 1.2, the DataProtectionApplication (DPA) configuration spec.configuration.velero.args has the following changes:

  • The default-volumes-to-restic field was renamed to default-volumes-to-fs-backup. If you use spec.velero, you must add it again with the new name to your DPA after upgrading OADP.

  • The default-volumes-to-restic field was renamed to default-volumes-to-fs-backup. If you use spec.velero, you must add it again with the new name to your DPA after upgrading OADP.

  • The restic-timeout field was renamed to fs-backup-timeout. If you use spec.velero, you must add it again with the new name to your DPA after upgrading OADP.

  • The restic daemon set was renamed to node-agent. OADP automatically updates the name of the daemon set.

  • The custom resource definition resticrepositories.velero.io was renamed to backuprepositories.velero.io.

  • The custom resource definition resticrepositories.velero.io can be removed from the cluster.

Upgrading steps

OADP 1.1.7 release notes

The OADP 1.1.7 release notes lists any resolved issues and known issues.

Resolved issues

The following highlighted issues are resolved in OADP 1.1.7:

Multiple HTTP/2 enabled web servers are vulnerable to a DDoS attack (Rapid Reset Attack)

In previous releases of OADP 1.1, the HTTP/2 protocol was susceptible to a denial of service attack because request cancellation could reset multiple streams quickly. The server had to set up and tear down the streams while not hitting any server-side limit for the maximum number of active streams per connection. This resulted in a denial of service due to server resource consumption. For a list of all OADP issues associated with this CVE, see the following Jira list.

For more information, see CVE-2023-39325 (Rapid Reset Attack).

For a complete list of all issues resolved in the release of OADP 1.1.7, see the list of OADP 1.1.7 resolved issues in Jira.

Known issues

There are no known issues in the release of OADP 1.1.7.

OADP 1.1.6 release notes

The OADP 1.1.6 release notes lists any new features, resolved issues and bugs, and known issues.

Resolved issues

Restic restore partially failing due to Pod Security standard

OCP 4.14 introduced pod security standards that meant the privileged profile is enforced. In previous releases of OADP, this profile caused the pod to receive permission denied errors. This issue was caused because of the restore order. The pod was created before the security context constraints (SCC) resource. As this pod violated the pod security standard, the pod was denied and subsequently failed. OADP-2420

Restore partially failing for job resource

In previous releases of OADP, the restore of job resource was partially failing in OCP 4.14. This issue was not seen in older OCP versions. The issue was caused by an additional label being to the job resource, which was not present in older OCP versions. OADP-2530

For a complete list of all issues resolved in this release, see the list of OADP 1.1.6 resolved issues in Jira.

OADP 1.1.4 release notes

The OADP 1.1.4 release notes lists any new features, resolved issues and bugs, and known issues.

New features

This version of OADP is a service release. No new features are added to this version.

Resolved issues

Add support for all the velero deployment server arguments

In previous releases of OADP, OADP did not facilitate the support of all the upstream Velero server arguments. This issue has been resolved in OADP 1.1.4 and all the upstream Velero server arguments are supported. OADP-1557

Data Mover can restore from an incorrect snapshot when there was more than one VSR for the restore name and pvc name

In previous releases of OADP, OADP Data Mover could restore from an incorrect snapshot if there was more than one Volume Snapshot Restore (VSR) resource in the cluster for the same Velero restore name and PersistentVolumeClaim (pvc) name. OADP-1822

Cloud Storage API BSLs need OwnerReference

In previous releases of OADP, ACM BackupSchedules failed validation because of a missing OwnerReference on Backup Storage Locations (BSLs) created with dpa.spec.backupLocations.bucket. OADP-1511

For a complete list of all issues resolved in this release, see the list of OADP 1.1.4 resolved issues in Jira.

Known issues

This release has the following known issues:

OADP backups might fail because a UID/GID range might have changed on the cluster

OADP backups might fail because a UID/GID range might have changed on the cluster where the application has been restored, with the result that OADP does not back up and restore OpenShift Container Platform UID/GID range metadata. To avoid the issue, if the backed application requires a specific UUID, ensure the range is available when restored. An additional workaround is to allow OADP to create the namespace in the restore operation.

A restoration might fail if ArgoCD is used during the process due to a label used by ArgoCD

A restoration might fail if ArgoCD is used during the process due to a label used by ArgoCD, app.kubernetes.io/instance. This label identifies which resources ArgoCD needs to manage, which can create a conflict with OADP’s procedure for managing resources on restoration. To work around this issue, set .spec.resourceTrackingMethod on the ArgoCD YAML to annotation+label or annotation. If the issue continues to persist, then disable ArgoCD before beginning to restore, and enable it again when restoration is finished.

OADP Velero plugins returning "received EOF, stopping recv loop" message

Velero plugins are started as separate processes. When the Velero operation has completed, either successfully or not, they exit. Therefore if you see a received EOF, stopping recv loop messages in debug logs, it does not mean an error occurred. The message indicates that a plugin operation has completed. OADP-2176
