We just have to trust SpiderOak, which is hard to do with a US company in light of Mr. But the One Backup desktop client, which is the heart of this product, is not.Īs with any closed source product, this means there is no way to know for sure that it is doing what it is supposed to, and only what it is supposed to. The One Backup mobiles apps have been fully open source since 2016, and various other products by SpiderOak are also open source. As far back as 2009, SpiderOak promised that it would move towards implementing only 100 percent open source code, but in 2024 the desktop client remains closed source.

The good news is, SpiderOak is also a zero-knowledge company that offers full end-to-end encryption of files backed-up to its servers. The US is a terrible place for online privacy, where it should be assumed that the NSA has access to all data stored in the country and all information held by companies located there. SpiderOak is a US company which stores backed-up data on servers located in the United States. This feature adds right-click menu options for SpiderOak One in Windows. Backups can also be accessed and managed via a web interface from any browser (including mobile). A mobile app is also available Android and iOS, although this has greatly reduced functionality. The desktop client is available for Windows, macOS, and Linux (Deb, RPP and Tarball). This can be done through its ShareRoom feature which creates a shared folder, or via creating temporary, self-destructing links to individual files.
