iTera Vault is from <a href=”http://www.visionsolutions.com/Products/High-Availability-iTERA-HA.aspx”>Vision Solutions</a>. You can sign up with them for a user account. Once you have an account you can download the documentation from their site.
If you are using the older iTera Vault – the name has changed to <a href=”http://www.visionsolutions.com/Products/Disaster-Recovery-RecoverNow.aspx”>Recover Now</a>.
If it’s HA, you’re probably using iTera HA not Vault, possibly version 5.0 and not the older Echo versions.
