SOS Online Backup Review

A Full Review of SOS Online Backup, an Online Backup Service

SOS Online Backup quit accepting new customers in early 2021. If you want a backup plan that has over 5 TB of storage, or you need something for 5+ users, they have a product called Infrascale Cloud Backup.

SOS Online Backup was an online backup service that offered a handful of consumer-grade plans. You could get anywhere from 50 GB to 5 TB of storage for five users. Below is more information on what the service was like. If you're looking for an alternative, see this list of online backup services.
