IDrive

Reviewers say IDrive offers more features than basic online backup services like MozyHome (*Est. $6 per month for 50 GB) or Carbonite (*Est. $55 per year for unlimited storage). IDrive offers 5 GB of storage for free, or you can opt for more storage with paid subscriptions, which start at $50 per year for 150 GB per computer. IDrive has useful features such as file searching and drag-and-drop file restoration. It also saves the last 30 versions of your files. Reviewers say these features set it apart from cheaper online backup services. Like most of its competitors, IDrive requires separate software, but there's also a Mac version. The interface has been redone, and reviewers say it's less cluttered and easier to navigate. Even so, some reviewers prefer SOS Online Backup (*Est. $80 per year for 50 GB), which offers unlimited file versioning and lots of other additional features.

IDrive gets decent coverage by reviewers. NotebookReview.com and PC Pro have the most recent reviews. Both sources also rate the service, which makes it easy to see how IDrive stacks up against the competition. Slightly older reviews at PCMag.com and CNET are also worth looking at.
