About image copy
You can create an image copy with two types of backup operations:
is the default copy and is marked as copy no 1.
is marked as copy no 2.
Whenever any backup-now operation or scheduled backup triggers, is taken. But, is optional as it depends whether option is selected or not while creating a protection plan.
An image group consists of asset images for metadata and Persistent Volume Claims (PVC). Every copy has one image for namespace and one image for each PVC present in the namespace.
Recovery point detail API is used to identify the copy completion status of an image. This API also details all the backup ids and resource name present in the respective copy. This complete or incomplete status of the image copy helps in restore functionality as an error is thrown if someone tries to restore the asset from an incomplete image copy.
Following are the conditions for an incomplete image:
When the snapshot job or backup from snapshot job is in progress then the corresponding copy is shown as incomplete copy.
If backup activity of any PVC fails, then the copy is marked as incomplete.
If the child image of a copy gets expired (with more than 1 child), then the copy is marked as incomplete.
