Some online backup services, including IDrive, LiveDrive, SpiderOak and SOS Online Backup, offer enhanced file versioning and the ability to manage multiple users or back up a variety of computers. For most users, experts recommend a simple, easy-to-use backup service like MozyHome or Crashplan+. However, more complex online backup may be for you if you want more control over your data.
Among full-featured online backup services, SOS Online Backup (Est. $10 per month for 100 GB and 5 computers) gets the best reviews. Plans with 150 GB (Est. $16 per month) and 250 GB (Est. $20 per month) are also available. It's more expensive than basic services, but reviewers say it offers significantly more functionality. Up to five Windows PCs, Macs, iPhones and Android devices can be backed up with one account, and you can access your files from any computer with an Internet connection, as well as via iPhone and Android mobile apps.
Additionally, your Facebook profile and files on external hard drives and network-attached storage drives can be backed up. If you want a local backup of your data, SOS Online Backup will also save your files to an external hard drive. SOS Online Backup offers robust sharing functionality, and you can send your files to others directly from the site's servers.
IDrive (Est. $50 per year for 150 GB) is another option for those who want a robust online backup service. In addition to the 150 GB plan, a 5 GB free account is available as well as plans that offer up to 2 TB of storage (Est. $1,500 per year), geared for small business owners with several computers. IDrive has lots of useful features such as file searching and drag-and-drop file restoration. It also saves the last 30 versions of your files. A Timeline Restore feature allows you to restore all your data to the way it was on a specific date.
LiveDrive (Est. $8 per month for unlimited GB) blurs the line between basic syncing and full-featured online backup services; the basic Backup subscription offers unlimited storage for a single PC, the Briefcase syncing plan (Est. $16 per month for 2 TB) synchronizes data Dropbox-style between multiple devices, and the Pro Suite subscription (Est. $25 per month) adds 5 TB of syncing space and unlimited storage for up to five computers. Reviewers say LiveDrive is a cinch to set up, and scheduling new folders to back up is as easy as right-clicking on them and selecting the appropriate option.
Overall, SOS Online Backup gets the best reviews and offers robust plans for multiple devices, making it our choice for best full-featured online backup.
