Trying to learn OADP backup, have broken the process in steps to make it easy to understand

[Ravi_Shanker]

Step 1:

Create Object Bucket Claim.

When object bucket claim is created it creates a secret and configmap with the same name in the same namespace as object bucket claim.

Step 2:

Extract the secret and configmap which will provide the bucket name, access key id and access key password.

Step 3:

Create secret with name as cloud-credentials in namespace openshift-adp using key and secret extracted from secret created in object bucket claims namespace.

cat credentials-velero

(default)

aws access key_id=AWS_ACCESS_KEY_ID

aws secret access_key=AWS_SECRET_ACCESS_KEY

oc create secret generic cloud-credentials -n openshift-adp --from-file=cloud=credentials-velero

Step 4:

Create DPA (Data Protection Application) resource once the cloud-credentials secret is created.

Step 5:

Label the volumesnapshotclass for OADP to use volume snapshot class.

oc label volumesnapshotclass <volume-snapshot-storageclass> velero.io/csi-volumesnapshot-class="true"

Confirm Deletion policy is set to Retain.
oc get volumesnapshotclass -l velero.io/csi-volumesnapshot-class=true --show-labels

Step 6:

Verify OADP is configured properly

oc -n openshift-adp get deploy

oc -n openshift-adp get daemonset

oc -n openshift-adp get backupstoragelocation

oc-n openshift-adp describe backupstoragelocation backupstoragelocation-name

s3cmd --configure

Note: OpenShift Data Foundation requires "signature_v2: True" option set in .s3cmd

@Ravi_Shanker Thanks for sharing. 

If I may just summarise in main points /steps what you have shared, here it is :

Step 1: Create ObjectBucketClaim (OBC)

Step 2: Extract Credentials

Step 3: Create cloud-credentials Secret

Step 4: Deploy the DPA (Data Protection Application)

Step 5: Configure CSI Volume Snapshots

Step 6: Verify OADP Deployment

Step 7( optional ) : For OpenShift Data Foundation, enable signature_v2
