You just purchased a ReadyNAS device, but the Vault is not working. Here is what you should do:
You need to update your firmware to get the latest version of Frontview/RAIDiator on the unit. To do so do this: Configure->Settings->Update. Once you run the update, the ReadyNAS Vault option is included under configuration->Backup->Vault.
Also, if you have any issues regarding the vault, you can email us at email@example.com.
