Updated January 07, 2019 58 58 people found this article helpful All online backup services offer basic features like automatic, regularly occurring, and incremental backup, as well as the ability to restore previously backed up data. Beyond that, however, online backup services start to show their differences. Some services allow backup from network drives while others don't. Only some allow device-to-device syncing. Only one that I've profiled below supports Linux. With so many differences, a feature comparison chart, like the one below, can help you decide which online backup service is best for you. Our Online Backup FAQ can help here, too. Most of the questions we've heard about cloud/online backup plans are answered there, in plain English! Wondering where the prices are? Most online backup services have several plans that differ in price based on storage and devices supported. See my Price Comparison: Unlimited Online Backup Plans and Price Comparison: Multi-Computer Online Backup Plans for updated information.

I may have that more detailed information in my review of the service (if I have one) or you may find it in the self-support area on the backup service's website. Features available only in a service's business-class online backup plan are not shown here.  Most online service providers automatically exclude certain file types you're unlikely to want to backup (like temporary files, extremely large files, etc.) but these exclusions can be removed if you want.  This feature is available in some, but not all, plans by this online backup provider.  This feature is available via an extra service/program from this provider.  Windows 8 Pro & 8.1 Pro are the only supported versions of Windows 8 for this backup provider's software.  This feature is only available if you're using Windows and only in some of this provider's online backup plans.  This feature is only available when backing up locally.
