# aboard storage

> Check file bytes or copy a disk store.

```text theme={null}
aboard storage check [--data PATH] [--db URL] [--files URL] | copy --from URL --to URL [--json]
```

For the server operator, in a terminal. Check opens the database read-only without migrations and verifies every historical file version. Copy verifies all blobs and skips intact bytes already at the destination. Both refuse in agent sessions.

## Flags

| Flag | What it does |
| - | - |
| `--data PATH` | The server data directory. |
| `--db URL` | The SQLite database URL. |
| `--files URL` | The disk blob store URL. |
| `--from URL` | The source disk store. |
| `--to URL` | The destination disk store. |
| `--json` | Print one JSON object instead of text, errors included. |

## Examples

```bash theme={null}
# Verify all stored versions
aboard storage check
```
