Restoring from backup removes essential uid in ownerReferences, breaking Ingress-Certificate relationship

I encountered an issue while restoring cert-manager resources from a backup using the recommended method in the official documentation: `kubectl apply -f <(awk '!/^ *(resourceVersion|uid): [^ ]+$/' backup.yaml)` However, this command unintentionally removes the **uid** field under **ownerReferences** in Certificate resources. This becomes a problem when certificates are generated via Ingress resources. The **uid** field in **ownerReferences** is essential for maintaining the relationship between the Ingress and the Certificate. Proposed solution To preserve the ownerReferences[].uid while still removing unnecessary metadata fields like metadata.uid and metadata.resourceVersion, I used the following jq-based workaround: ``` jq 'walk(if type == "object" and has("metadata") then .metadata |= (del(.uid) | del(.resourceVersion)) else . end)' \ backup.yaml | kubectl apply -f - ``` This ensures that: metadata.uid and metadata.resourceVersion are removed (as expected) ownerReferences[].uid is preserved to maintain resource relationships
