What this PR does / why we need it:

The backup/restore README only documented AWS prerequisites despite
the tests already supporting Agent and KubeVirt platforms. Add a new
section covering MinIO-based OADP setup (storage, credentials, DPA,
BSL, VSL) used by both platforms in CI, and document Agent-specific
CAPI resource pausing behavior during backup/restore operations.

Which issue(s) this PR fixes:

Fixes https://redhat.atlassian.net/browse/CNTRLPLANE-2029

Special notes for your reviewer:

Checklist:

  • Subject and description added to both, commit and PR.

📝 Walkthrough

Walkthrough

The Backup and Restore E2E README now documents AWS, Agent, and KubeVirt support. It adds MinIO deployment, credential secret, and OADP/Velero configuration instructions for Agent and KubeVirt environments. It documents Agent pause and unpause behavior and states that the BackupRestoreEtcdSnapshot test remains AWS-only.

Suggested reviewers: enxebre, nirshal

Merge Risk: 🔵 Low · up to 823b7

The README adds useful platform setup guidance, but the current examples should replace hard-coded credentials and align the configured bucket name before merge; otherwise users could expose credentials or have backup configuration point to a nonexistent bucket.

Stable And Deterministic Test Names ✅ Passed The aggregate PR diff changes only README.md. It adds no Ginkgo test declarations or titles, and the documented test names are static.
Test Structure And Quality ✅ Passed The HEAD^ diff changes only test/e2e/v2/backuprestore/README.md; no Ginkgo test code changed, so the stated test-structure requirements are inapplicable.

Ipv6 And Disconnected Network Test Compatibility ✅ Passed The PR changes only test/e2e/v2/backuprestore/README.md; no Ginkgo test declarations or test code were added, so this check is not applicable.
No-Weak-Crypto ✅ Passed The PR changes only the backup/restore README; its MinIO setup uses S3v4 and contains no MD5, SHA1, DES, RC4, Blowfish, ECB, custom crypto, or secret comparisons.
Container-Privileges ✅ Passed The PR changes only README.md. Its added MinIO and OADP examples contain no privileged:true, hostPID/Network/IPC, SYS_ADMIN, allowPrivilegeEscalation, or root user setting.
No-Sensitive-Data-In-Logs ✅ Passed The PR changes only README.md. It adds no logging statements or log content; the MinIO password and virthost IP appear only in setup examples, and debug is configuration, not sensitive-data logging.

Is the VolumeSnapshotLocation actually needed for Agent/KubeVirt? These platforms don't use cloud-provider volume snapshots — they typically use CSI snapshots or Kopia. The region: minio config looks like it was carried over from the AWS structure. If backup/restore works without a VSL on these platforms, we should either drop this block or add a note explaining why it's still needed.

Good point. We use it in our set up: https://github.com/openshift/release/blob/main/ci-operator/step-registry/hypershift/mce/agent/oadp/v2/setup/hypershift-mce-agent-oadp-v2-setup-commands.sh#L89
But I will have to re-test it to verify if VolumeSnapshotLocation is not required there. I will try a test PR and reply back here.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Propagate a custom bucket name to the BSL.

The deployment example allows a custom bucket_name, but this block resets it to "oadp-backup". If the MinIO block creates a different bucket, the BackupStorageLocation points to a bucket that was not created. Use the same value in both blocks.

Also applies to: 256-258
