SOS Online Backup Review

Updated May 31, 2014
SOS Online Backup

SOS Online Backup supports up to five computers or Apple devices and backs up data both online and locally. The service can also back up Apple and Android smartphones and tablets. Mobile support is robust and SOS Online Backup has unlimited file versioning. Reviewers say that while it has more functionality than competing services, including unlimited file versioning, SOS Online Backup also sports an easy-to-use interface with advanced customization options.

Backs up many devices; never deletes your data. SOS Online Backup is packed with features, although that comes at a higher cost than competing online backup services. While most services only back up Windows PCs or Macs, SOS can also back up iPhones, Facebook profiles, Android phones or tablets, and external hard drives or network-attached storage drives. You can back up five computers with one account and access your files from any computer with Internet access. There are also numerous features that allow you to share files with friends.

SOS offers much more security than other online backup services. SOS Online Backup protects your data locally with 256-bit AES encryption and transfers information to the company's servers over a 128-bit SSL connection. It then secures your data even further at its data center, slapping an additional layer of 1,024-bit AES encryption.

SOS Online Backup never deletes your data, even if you do; it offers unlimited file versioning, meaning that if you unexpectedly need a file you deleted a year ago, SOS will let you restore it.


No unlimited storage plan. Like MozyHome, SOS Online Backup doesn't offer an unlimited storage option; instead, the basic plan at $10 per month allows up to 100 GB of data from up to five different computers or devices. Options with 150 GB (Est. $16 per month) and 250 GB (Est. $20 per month) are also available, with discounts available with yearly subscriptions. There are no unlimited storage plans, a situation that some reviewers complain about. (As of May 2013, the SOS website is advertising unlimited plans starting at $10 per month, but it's not clear how long that will last.)
