# Interface CloudSyncSummary

Read-only mirror of the host's cloud entity-sync engine (§27): the backup of this device's entities to the tenant mirror plus the pull of cloud-authored ones. Presentational and id-free — no seqs, cursors, or row identities.

```typescript
interface CloudSyncSummary {
    enabled: boolean;
    lastError: string | null;
    lastSyncedAt: string | null;
    skippedOversized: number;
    surface?: CloudSyncSurfaceStatus;
    syncing: boolean;
}
```

Types: [enabled](#enabled), [lastError](#lasterror), [lastSyncedAt](#lastsyncedat), [skippedOversized](#skippedoversized), [surface](#surface), [CloudSyncSurfaceStatus](core.CloudSyncSurfaceStatus.md), [syncing](#syncing)

Rows skipped as too large to back up (surfaced, never silent).

### <a id="surface"></a>`Optional`surface

```typescript
surface?: CloudSyncSurfaceStatus
```

Types: [CloudSyncSurfaceStatus](core.CloudSyncSurfaceStatus.md)

The closed nine-state sync-surface projection (W6). Optional/additive: the five fields above keep working for existing consumers unchanged.
