While IDrive does not specifically offer a free trial, they feature a forever-free Basic plan, which is more than decent for casual users or simply to give the service a try. They also offer the ability to refund monthly and yearly subscriptions provided that your account is cancelled within 15 days of its creation day. If there is a technical issue, yearly refunds can be provided but on a case-by-case basis.
