IDrive is a well-rounded backup service that lets you save data from an unlimited number of devices into a single account. While IDrive does not specifically offer a free trial, it features a forever-free Basic plan with 5GB of backup storage and 5GB of syncing space, which is more than decent for casual users. Though the free version already comes with most essential features, you can take advantage of a 15-day money-back guarantee to test paid versions of the software. If there is a technical issue, annual account refunds can be provided on a case-by-case basis.
