using either. idrive will also handily create a local backup using the same data set that’s being backed up online. That allows you to painlessly maintain the Rule of Three: your original data, a copy, and a copy of the copy. Also, it’s much faster to restore from a hard drive than from any online service. If you don’t require online document editing, idrive truly has the most comprehensive set of backup and backup-related features of any online service we’ve tested. And, they’re all available at the basic service level, making idrive less expensive than it seems. Good stuff. Mozy ( go.pcworld.com/m0zy) is the only close competitor we’ve reviewed so far, and worth a mention.
