Duplicate resource storage key in manifest: ${key}

Error message

Duplicate resource storage key in manifest: ${key}

What it means

Thrown when a storage key appears in originalStorageKeys across two different resources. The manifest treats storage keys as globally unique (one physical blob per key), so any cross-resource reuse is rejected.

Solutions

1. Pick one resource to own the key and remove it from the other.
2. Re-export with global storage-key deduplication.
3. Verify the storage backend doesn't alias keys.

Example fix

// before
validateBackupManifestGraph(manifest)

// after
const claimed = new Set<string>()
for (const r of manifest.resources) {
  r.originalStorageKeys = r.originalStorageKeys.filter((k) =>
    claimed.has(k) ? false : (claimed.add(k), true)
  )
}

function findSharedStorageKeys(manifest: BackupManifest): string[] {
  const seen = new Set<string>()
  const dups = new Set<string>()
  for (const r of manifest.resources) for (const k of r.originalStorageKeys) (seen.has(k) ? dups : seen).add(k)
  return [...dups]
}

try {
  validateBackupManifestGraph(manifest)
} catch (error) {
  if (/Duplicate resource storage key/.test((error as Error).message)) reportSharedStorageKey(error)
  throw error
}

When it happens

Trigger: Two distinct resource entries both list the same key in their originalStorageKeys.

Common situations: Two resources point at the same underlying blob; exporter failed to deduplicate storage keys globally; merge of backups that share storage.
