Online Backup Comparison

A Comparison of Features Offered by the Best Online Backup Services


Updated July 2014

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 I've profiled below supports Linux. With so many differences, a feature comparison chart can help you decide which online backup service is best for you.

My Online Backup Q&A may help too, which is a series of interviews with online backup providers, allowing you to compare responses to important questions about NSA access, usage limits, and more. See my Online Backup FAQ for even more help.

Where Are the Prices? 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.

Important: While the feature list I've created above is pretty extensive and I've further clarified some information here in the footnotes, you should deeper investigate any online backup service's feature that you're particularly interested in before you decide to purchase one of their plans. 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.

Note: Features available only in a service's business-class online backup plan are not shown here.

[1] 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.

[2] This feature is available in some, but not all, plans by this online backup provider.

[3] This feature is available via an extra service/program from this provider.

[4] Windows 8 Pro & 8.1 Pro are the only supported versions of Windows 8 for this backup provider's software.

[5] This feature is available with this online backup service's software but only when installed on some operating systems.
