$ BUCKET=<your_bucket>
You install the OpenShift API for Data Protection (OADP) with Amazon Web Services (AWS) S3 compatible storage by installing the OADP Operator. The Operator installs Velero 1.14.
IBM Cloud® S3 is supported as an AWS S3 compatible backup storage provider.
Starting from OADP 1.0.4, all OADP 1.0.z versions can only be used as a dependency of the MTC Operator and are not available as a standalone Operator. |
You configure AWS for Velero, create a default Secret
, and then install the Data Protection Application. For more details, see Installing the OADP Operator.
To install the OADP Operator in a restricted network environment, you must first disable the default OperatorHub sources and mirror the Operator catalog. See Using Operator Lifecycle Manager on restricted networks for details.
You configure Amazon Web Services (AWS) for the OpenShift API for Data Protection (OADP).
You must have the AWS CLI installed.
Set the BUCKET
variable:
$ BUCKET=<your_bucket>
Set the REGION
variable:
$ REGION=<your_region>
Create an AWS S3 bucket:
$ aws s3api create-bucket \
--bucket $BUCKET \
--region $REGION \
--create-bucket-configuration LocationConstraint=$REGION (1)
1 | us-east-1 does not support a LocationConstraint . If your region is us-east-1 , omit --create-bucket-configuration LocationConstraint=$REGION . |
Create an IAM user:
$ aws iam create-user --user-name velero (1)
1 | If you want to use Velero to back up multiple clusters with multiple S3 buckets, create a unique user name for each cluster. |

You use the credentials-velero
file to create a Secret
object for AWS before you install the Data Protection Application.
You specify backup and snapshot locations and their secrets in the DataProtectionApplication
custom resource (CR).
You specify AWS S3-compatible object storage as a backup location, such as Multicloud Object Gateway; Red Hat Container Storage; Ceph RADOS Gateway, also known as Ceph Object Gateway; Red Hat OpenShift Data Foundation; or MinIO.
Velero backs up OpenShift Container Platform resources, Kubernetes objects, and internal images as an archive file on object storage.
If you use your cloud provider’s native snapshot API to back up persistent volumes, you must specify the cloud provider as the snapshot location.
If you use Container Storage Interface (CSI) snapshots, you do not need to specify a snapshot location because you will create a VolumeSnapshotClass
CR to register the CSI driver.
If you use File System Backup (FSB), you do not need to specify a snapshot location because FSB backs up the file system on object storage.
If the backup and snapshot locations use the same credentials or if you do not require a snapshot location, you create a default Secret
.
If the backup and snapshot locations use different credentials, you create two secret objects:
Custom Secret
for the backup location, which you specify in the DataProtectionApplication
CR.
Default Secret
for the snapshot location, which is not referenced in the DataProtectionApplication
CR.
The Data Protection Application requires a default If you do not want to specify backup or snapshot locations during the installation, you can create a default |
You create a default Secret

Your object storage and cloud storage, if any, must use the same credentials.
You must configure object storage for Velero.
You must create a credentials-velero
file for the object storage in the appropriate format.
Create a Secret
with the default name:
$ oc create secret generic cloud-credentials -n openshift-adp --from-file cloud=credentials-velero
The Secret
is referenced in the spec.backupLocations.credential
block of the DataProtectionApplication
CR when you install the Data Protection Application.
If your backup and snapshot locations use different credentials, you create separate profiles in the credentials-velero
file.
Then, you create a Secret
object and specify the profiles in the DataProtectionApplication
custom resource (CR).
Create a credentials-velero
file with separate profiles for the backup and snapshot locations, as in the following example:
[backupStorage]
aws_access_key_id=<AWS_ACCESS_KEY_ID>
aws_secret_access_key=<AWS_SECRET_ACCESS_KEY>
[volumeSnapshot]
aws_access_key_id=<AWS_ACCESS_KEY_ID>
aws_secret_access_key=<AWS_SECRET_ACCESS_KEY>
Create a Secret
object with the credentials-velero
file:
$ oc create secret generic cloud-credentials -n openshift-adp --from-file cloud=credentials-velero (1)
Add the profiles to the DataProtectionApplication
CR, as in the following example:
apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
name: <dpa_sample>
namespace: openshift-adp

Amazon Web Services (AWS) S3 applies server-side encryption with Amazon S3 managed keys (SSE-S3) as the base level of encryption for every bucket in Amazon S3.
OpenShift API for Data Protection (OADP) encrypts data by using SSL/TLS, HTTPS, and the velero-repo-credentials
secret when transferring the data from a cluster to storage. To protect backup data in case of lost or stolen AWS credentials, apply an additional layer of encryption.
The velero-plugin-for-aws plugin provides several additional encryption methods. You should review its configuration options and consider implementing additional encryption.
You can store your own encryption keys by using server-side encryption with customer-provided keys (SSE-C). This feature provides additional security if your AWS credentials become exposed.
Be sure to store cryptographic keys in a secure and safe manner. Encrypted data and backups cannot be recovered if you do not have the encryption key. |
To make OADP mount a secret that contains your SSE-C key to the Velero pod at /credentials
, use the following default secret name for AWS: cloud-credentials
, and leave at least one of the following labels empty:
dpa.spec.backupLocations[].velero.credential
dpa.spec.snapshotLocations[].velero.credential
This is a workaround for a known issue: https://issues.redhat.com/browse/OADP-3971.
The following procedure contains an example of a |
If you need the backup location to have credentials with a different name than cloud-credentials
, you must add a snapshot location, such as the one in the following example, that does not contain a credential name. Because the example does not contain a credential name, the snapshot location will use cloud-credentials
as its secret for taking snapshots.
snapshotLocations:
- velero:
config:
profile: default
region: <region>
provider: aws
# ...
Create an SSE-C encryption key:
Generate a random number and save it as a file named sse.key
by running the following command:
$ dd if=/dev/urandom bs=1 count=32 > sse.key
Encode the sse.key
by using Base64 and save the result as a file named sse_encoded.key
by running the following command:
$ cat sse.key | base64 > sse_encoded.key
Link the file named sse_encoded.key
to a new file named customer-key
by running the following command:
$ ln -s sse_encoded.key customer-key
Create an OpenShift Container Platform secret:
If you are initially installing and configuring OADP, create the AWS credential and encryption key secret at the same time by running the following command:
$ oc create secret generic cloud-credentials --namespace openshift-adp --from-file cloud=<path>/openshift_aws_credentials,customer-key=<path>/sse_encoded.key
If you are updating an existing installation, edit the values of the cloud-credential
secret
block of the DataProtectionApplication
CR manifest, as in the following example:
apiVersion: v1
data:
cloud: W2Rfa2V5X2lkPSJBS0lBVkJRWUIyRkQ0TlFHRFFPQiIKYXdzX3NlY3JldF9hY2Nlc3Nfa2V5P<snip>rUE1mNWVSbTN5K2FpeWhUTUQyQk1WZHBOIgo=
customer-key: v+<snip>TFIiq6aaXPbj8dhos=
kind: Secret
# ...
Edit the value of the customerKeyEncryptionFile
attribute in the backupLocations
block of the DataProtectionApplication
CR manifest, as in the following example:
spec:
backupLocations:
- velero:
config:
customerKeyEncryptionFile: /credentials/customer-key
profile: default
# ...
You must restart the Velero pod to remount the secret credentials properly on an existing installation. |
The installation is complete, and you can back up and restore OpenShift Container Platform resources. The data saved in AWS S3 storage is encrypted with the new key, and you cannot download it from the AWS S3 console or API without the additional encryption key.
To verify that you cannot download the encrypted files without the inclusion of an additional key, create a test file, upload it, and then try to download it.
Create a test file by running the following command:
$ echo "encrypt me please" > test.txt
Upload the test file by running the following command:
$ aws s3api put-object \
--bucket <bucket> \
--key test.txt \
--body test.txt \
--sse-customer-key fileb://sse.key \
--sse-customer-algorithm AES256
Try to download the file. In either the Amazon web console or the terminal, run the following command:
$ s3cmd get s3://<bucket>/test.txt test.txt
The download fails because the file is encrypted with an additional key.
Download the file with the additional encryption key by running the following command:
$ aws s3api get-object \
--bucket <bucket> \
--key test.txt \
--sse-customer-key fileb://sse.key \
--sse-customer-algorithm AES256 \
downloaded.txt
Read the file contents by running the following command:
$ cat downloaded.txt
encrypt me please
You can also download the file with the additional encryption key backed up with Velcro by running a different command. See Downloading a file with an SSE-C encryption key for files backed up by Velero.
When you are verifying an SSE-C encryption key, you can also download the file with the additional encryption key for files that were backed up with Velcro.
Download the file with the additional encryption key for files backed up by Velero by running the following command:
$ aws s3api get-object \
--bucket <bucket> \
--key velero/backups/mysql-persistent-customerkeyencryptionfile4/mysql-persistent-customerkeyencryptionfile4.tar.gz \
--sse-customer-key fileb://sse.key \
--sse-customer-algorithm AES256 \

You can configure the Data Protection Application by setting Velero resource allocations or enabling self-signed CA certificates.
You set the CPU and memory resource allocations for the Velero
pod by editing the DataProtectionApplication
custom resource (CR) manifest.
You must have the OpenShift API for Data Protection (OADP) Operator installed.
Edit the values in the spec.configuration.velero.podConfig.ResourceAllocations
block of the DataProtectionApplication
CR manifest, as in the following example:
apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
name: <dpa_sample>
spec:
# ...
configuration:
velero:
podConfig:
nodeSelector: <node_selector> (1)
resourceAllocations: (2)
limits:
cpu: "1"
memory: 1024Mi
requests:
cpu: 200m
memory: 256Mi
1 | Specify the node selector to be supplied to Velero podSpec. |
2 | The resourceAllocations listed are for average usage. |
Kopia is an option in OADP 1.3 and later releases. You can use Kopia for file system backups, and Kopia is your only option for Data Mover cases with the built-in Data Mover. Kopia is more resource intensive than Restic, and you might need to adjust the CPU and memory requirements accordingly. |
Use the nodeSelector
field to select which nodes can run the node agent. The nodeSelector
field is the simplest recommended form of node selection constraint. Any label specified must match the labels on each node.
For more details, see Configuring node agents and node labels.
You must enable a self-signed CA certificate for object storage by editing the DataProtectionApplication
custom resource (CR) manifest to prevent a certificate signed by unknown authority
error.
You must have the OpenShift API for Data Protection (OADP) Operator installed.
Edit the spec.backupLocations.velero.objectStorage.caCert
parameter and spec.backupLocations.velero.config
parameters of the DataProtectionApplication
CR manifest:
apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication

# ...
1 | Specify the Base64-encoded CA certificate string. |
2 | The insecureSkipTLSVerify configuration can be set to either "true" or "false" . If set to "true" , SSL/TLS security is disabled. If set to "false" , SSL/TLS security is enabled. |
You might want to use the Velero CLI without installing it locally on your system by creating an alias for it.
You must be logged in to the OpenShift Container Platform cluster as a user with the cluster-admin
role.
You must have the OpenShift CLI (oc
) installed.
To use an aliased Velero command, run the following command:
$ alias velero='oc -n openshift-adp exec deployment/velero -c velero -it -- ./velero'
Check that the alias is working by running the following command:
$ velero version
Client:
Version: v1.12.1-OADP
Git commit: -
Server:
Version: v1.12.1-OADP
To use a CA certificate with this command, you can add a certificate to the Velero deployment by running the following commands:
$ CA_CERT=$(oc -n openshift-adp get dataprotectionapplications.oadp.openshift.io <dpa-name> -o jsonpath='{.spec.backupLocations[0].velero.objectStorage.caCert}')
$ [[ -n $CA_CERT ]] && echo "$CA_CERT" | base64 -d | oc exec -n openshift-adp -i deploy/velero -c velero -- bash -c "cat > /tmp/your-cacert.txt" || echo "DPA BSL has no caCert"
$ velero describe backup <backup_name> --details --cacert /tmp/<your_cacert>.txt
To fetch the backup logs, run the following command:
$ velero backup logs <backup_name> --cacert /tmp/<your_cacert.txt>
You can use these logs to view failures and warnings for the resources that you cannot back up.
If the Velero pod restarts, the /tmp/your-cacert.txt
file disappears, and you must re-create the /tmp/your-cacert.txt
file by re-running the commands from the previous step.
You can check if the /tmp/your-cacert.txt
file still exists, in the file location where you stored it, by running the following command:
$ oc exec -n openshift-adp -i deploy/velero -c velero -- bash -c "ls /tmp/your-cacert.txt"
/tmp/your-cacert.txt
In a future release of OpenShift API for Data Protection (OADP), we plan to mount the certificate to the Velero pod so that this step is not required.
You install the Data Protection Application (DPA) by creating an instance of the DataProtectionApplication
API.
You must install the OADP Operator.
You must configure object storage as a backup location.
If you use snapshots to back up PVs, your cloud provider must support either a native snapshot API or Container Storage Interface (CSI) snapshots.
If the backup and snapshot locations use the same credentials, you must create a Secret

Use the same custom label in the DPA.spec.configuration.nodeAgent.podConfig.nodeSelector
, which you used for labeling nodes. For example:
configuration:
nodeAgent:
enable: true
podConfig:
nodeSelector:
node-role.kubernetes.io/nodeAgent: ""
The following example is an anti-pattern of nodeSelector
and does not work unless both labels, 'node-role.kubernetes.io/infra: ""'
and 'node-role.kubernetes.io/worker: ""'
, are on the node:
configuration:
nodeAgent:
enable: true
podConfig:
nodeSelector:
node-role.kubernetes.io/infra: ""
node-role.kubernetes.io/worker: ""
You can configure the Backup Storage Location (BSL) in the Data Protection Application (DPA) to use a MD5 checksum algorithm for both Amazon Simple Storage Service (Amazon S3) and S3-compatible storage providers. The checksum algorithm calculates the checksum for uploading and downloading objects to Amazon S3. You can use one of the following options to set the checksumAlgorithm
field in the spec.backupLocations.velero.config.checksumAlgorithm
section of the DPA.
CRC32
CRC32C
SHA1
SHA256
You can also set the If you do not set a value for the |
You have installed the OADP Operator.
You have configured Amazon S3, or S3-compatible object storage as a backup location.
Configure the BSL in the DPA as shown in the following example:
apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
name: test-dpa
namespace: openshift-adp
spec:
backupLocations:
- name: default
velero:

s3ForcePathStyle: "true"
s3Url: <bucket_url>
credential:
key: cloud

default: true
objectStorage:
bucket: <bucket_name>
prefix: velero

1 | Specify the checksumAlgorithm . In this example, the checksumAlgorithm field is set to an empty value. You can select an option from the following list: CRC32 , CRC32C , SHA1 , SHA256 . |
If you are using Noobaa as the object storage provider, and you do not set the The empty value is only added for BSLs that are created using the DPA. This value is not added if you create the BSL by using any other method. |
You can configure the DPA with more than one BSL and specify the credentials provided by the cloud provider.
You must install the OADP Operator.
You must create the secrets by using the credentials provided by the cloud provider.
Configure the DPA with more than one BSL. See the following example.
apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
#...
backupLocations:
- name: aws (1)
velero:
provider: aws
default: true (2)
objectStorage:
bucket: <bucket_name> (3)
prefix: <prefix> (4)
config:
region: <region_name> (5)
profile: "default"
credential:
key: cloud
name: cloud-credentials (6)
- name: odf (7)
velero:
provider: aws
default: false
objectStorage:
bucket: <bucket_name>

s3Url: <url> (8)
insecureSkipTLSVerify: "true"
s3ForcePathStyle: "true"
credential:

name: <custom_secret_name_odf> (9)
#...
1 | Specify a name for the first BSL. |
2 | This parameter indicates that this BSL is the default BSL. If a BSL is not set in the Backup CR , the default BSL is used. You can set only one BSL as the default. |
3 | Specify the bucket name. |
4 | Specify a prefix for Velero backups; for example, velero . |
5 | Specify the AWS region for the bucket. |
6 | Specify the name of the default Secret object that you created. |
7 | Specify a name for the second BSL. |
8 | Specify the URL of the S3 endpoint. |
9 | Specify the correct name for the Secret ; for example, custom_secret_name_odf . If you do not specify a Secret name, the default name is used. |
Specify the BSL to be used in the backup CR. See the following example.
apiVersion: velero.io/v1
kind: Backup
# ...
spec:
includedNamespaces:
- <namespace> (1)
storageLocation: <backup_storage_location> (2)
defaultVolumesToFsBackup: true
1 | Specify the namespace to back up. |
2 | Specify the storage location. |
You enable the Container Storage Interface (CSI) in the DataProtectionApplication
custom resource (CR) in order to back up persistent volumes with CSI snapshots.
The cloud provider must support CSI snapshots.
Edit the DataProtectionApplication
CR, as in the following example:
apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
...
spec:
configuration:
velero:
defaultPlugins:
- openshift
- csi (1)
1 | Add the csi default plugin. |
If you are not using Restic
, Kopia
, or DataMover
for your backups, you can disable the nodeAgent
field in the DataProtectionApplication
custom resource (CR). Before you disable nodeAgent
, ensure the OADP Operator is idle and not running any backups.
To disable the nodeAgent
, set the enable
flag to false
. See the following example:
DataProtectionApplication
CR# ...
configuration:
nodeAgent:
enable: false (1)
uploaderType: kopia
# ...
1 | Disables the node agent. |
To enable the nodeAgent
, set the enable
flag to true
. See the following example:
DataProtectionApplication
CR# ...
configuration:
nodeAgent:
enable: true (1)
uploaderType: kopia
# ...
1 | Enables the node agent. |
You can set up a job to enable and disable the nodeAgent
field in the DataProtectionApplication
CR. For more information, see "Running tasks in pods using jobs".
