= Creating a Backup CR
|
|
|
|
You back up Kubernetes images, internal images, and persistent volumes (PVs) by creating a `Backup` custom resource (CR).
|
|
|
|
.Prerequisites
|
|
|
|
* You must install the OpenShift API for Data Protection (OADP) Operator.
|
|
* The `DataProtectionApplication` CR must be in a `Ready` state.
|
|
* Backup location prerequisites:
|
|
** You must have S3 object storage configured for Velero.
|
|
** You must have a backup location configured in the `DataProtectionApplication` CR.
|
|
* Snapshot location prerequisites:
|
|
** Your cloud provider must have a native snapshot API or support Container Storage Interface (CSI) snapshots.
|
|
** For CSI snapshots, you must create a `VolumeSnapshotClass` CR to register the CSI driver.
|
|
** You must have a volume location configured in the `DataProtectionApplication` CR.
|

.Procedure
|
|
|
|
. Retrieve the `backupStorageLocations` CRs by entering the following command:
|
|
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc get backupStorageLocations
|
|
----
|
|

|
|
.Example output
|
|
+
|
|
[source,terminal]
|
|
----
|
|
NAME PHASE LAST VALIDATED AGE DEFAULT
|
|

|
|
----
|
|
|
|
. Create a `Backup` CR, as in the following example:
|
|
+
|
|
[source,yaml]
|

|
|
<1> Specify an array of namespaces to back up.
|
|
<2> Optional: Specify an array of resources to include in the backup. Resources might be shortcuts (for example, 'po' for 'pods') or fully-qualified. If unspecified, all resources are included.
|
|
<3> Optional: Specify an array of resources to exclude from the backup. Resources might be shortcuts (for example, 'po' for 'pods') or fully-qualified.
|
|
<4> Specify the name of the `backupStorageLocations` CR.
|
|
|
|
. Verify that the status of the `Backup` CR is `Completed`:
|

|
|
[source,terminal]
|
|
----
|
|
$ oc get backup -n openshift-adp <backup> -o jsonpath='{.status.phase}'
