let kvStore: distributedKVStore.SingleKVStore | undefined = undefined;//kvStore获取步骤省略
let backupFile = 'BK001';
try {
  kvStore.restore(backupFile, (err) => {
    if (err) {
      console.error(`Fail to restore data. Code:${err.code},message:${err.message}`);
    } else {
      console.info('Succeeded in restoring data.');
    }

} catch (e) {
  let error = e as BusinessError;
  console.error(`An unexpected error occurred. Code:${error.code},message:${error.message}`);
