Q

Outline the first three steps in the OADP backup process.

Study These Flashcards
A
  1. Create a backup resource in the openshift-adp namespace.
  2. Velero exports all Kubernetes resources to the backup storage location.
  3. Velero creates a CSI snapshot of the application volume.
20
Q

What happens to volume snapshots and PVCs after the backup process completes?

Study These Flashcards
A

Data Mover deletes all volume snapshots and PVCs created during the backup process.

21
Q

Outline the first three steps in the OADP restore process.

Study These Flashcards
A
