Restore reliable scheduled credential-store snapshots #5376
Description
🤖 Generated by the Agentic Engineer
Description
A scheduled credential-store snapshot did not complete within its existing execution deadline. Diagnose and repair the failure before treating recent snapshot coverage as verified.
Expected Behavior
Each scheduled run produces a fresh usable snapshot, mirrors it off-cluster and reports bounded failure when it cannot complete. Retained copies and recovery credentials remain protected.
Actual Behavior
The 26 October execution records DeadlineExceeded. An earlier successful execution remains, but the failed pod is no longer available. The failing phase and cause are not established. Operational identifiers and evidence remain in the private run record.
Steps to Investigate
- Inspect the retained scheduled execution and existing private telemetry without reading or publishing credential values.
- Establish whether scheduling, storage attachment, snapshot creation or off-cluster mirroring failed; do not infer the phase from the Job's final deadline alone.
- Reproduce the identified cause and repair its owning configuration or code.
Acceptance Criteria
- Establish the failing phase and root cause with bounded private evidence and a meaningful regression where appropriate.
- Preserve concurrency exclusion, execution bounds, snapshot-before-mirror ordering, least privilege, retention and recovery access. Do not hide the failure by extending a timeout or reducing resource requests.
- Pass current-head validation, substantive review, protected merge and deployment.
- Observe a new complete snapshot and independently verify its off-cluster copy and recovery suitability. Preserve previous failed records.
Additional Context
Found during the private-mail backup-readiness assessment for #5030. This is distinct from #4723's established filesystem-transfer admission failure; no common cause is asserted. It is not an immediate service-outage claim. Size: Medium; root-cause refinement remains required.

Retained event history identifies storage attachment as the failed phase. The storage driver repeatedly reports that the backing volume cannot be found while the existing Kubernetes claim still reports Bound. Snapshot creation and off-cluster mirroring could not start.
The cause of the missing provider reference is still unverified. Preserve the existing claim and failed execution while checking the expected provider project and recovery copies, then prepare a data-preserving repair. No retry, storage deletion, resource reduction or deadline extension has been applied. Private identifiers and the bounded event evidence remain in the private run record.

The repair delivered through #5386, #5470 and #5406 (merged 2026-10-28) is live. The snapshot schedule now writes to the retained recovery storage, and the initial snapshot it took after deployment completed and its off-cluster copy reported verified. The three earlier failed scheduled executions are preserved.
What is left is the last acceptance criterion: a scheduled run must produce a fresh snapshot with a verified off-cluster copy. The first scheduled run on the repaired configuration is due at 03:30 UTC on 2026-10-29, and nothing can make it happen sooner. The card goes to Ready with
Measure on: 2026-10-29.Next action, on or after that run: read that execution's result and its remote-copy verification. Close this issue if both pass. If either fails, investigate the failure here.

Measured 2026-10-29: the last acceptance criterion passes.
The first scheduled snapshot on the repaired configuration ran at 03:30 UTC and completed in about 30 seconds. It reported the snapshot complete, and its off-cluster copy reported verified. The earlier failed scheduled executions are still preserved.
All acceptance criteria are now met, so this is closed. A future failure of the schedule should be opened as a new issue.
