Disaster recovery looks successful and later an application shows unexpected historical state because the restored snapshot lineage was not the one intended.
A PVC snapshot restore looks complete and the app still corrupts writes
The restore object exists, yet the attached data is wrong because operators trusted a display name rather than the underlying snapshot identity.
Scenario
What to check first
- Identify the primary failure signal in the The Snapshot Name Matched and the Data Lineage Did Not scenario.
- Separate visible symptoms from the underlying technical dependency.
- Describe the safest recovery path and the follow-up prevention work.
Checking checklist
- Summarize the current impact and the last known change.
- Collect direct evidence from logs, runtime state, and configuration before changing anything.
- Separate immediate recovery from permanent prevention work.
Recovery and prevention
Validate snapshot content identity and namespace lineage before re-running restores.
Questions worth viewing together
Community-field Kubernetes problem inspired by storage restore discussions where a VolumeSnapshot restore bound to the wrong content lineage. Friendly snapshot names can mask wrong lineage in multi-tenant or repeated DR workflows.
Teams often blame application cache warmup when the restored data set was from a different snapshot lineage entirely.
Snapshot restore workflows should validate the bound content UID, not only the human-readable snapshot name.
