SpiderOak is a US based[2] online backup tool to back up, share, sync, access and store[3] data using an off-site server. SpiderOak is accessible through an app for Windows, Mac and Linux computer platforms, and Android, N900 Maemo and iOS mobile platforms.[4] SpiderOak allows the user to back up any given folder of his/her computer. SpiderOak uses encrypted cloud storage and client-side encryption key creation, so even employees of SpiderOak cannot access users' information. However, these claims cannot be independently verified since the client's source is not available.[5] Some components of SpiderOak are open source, and the company has announced their intent for the client to be fully open source in the future.[6]

SpiderOak distinguishes itself from competition in provision of encryption,[7] in provision for syncing files and folders across multiple devices, and in automatic de-duplication of data.[8]

SpiderOak offers two account types, a free 5 GB version and a paid subscription for capacity above the free account limit. Users can also create a referral link, and each time the link is used to sign up for an account, an extra 1GB will be allotted to both accounts. The maximum account size that can be attained in this manner is 10GB.

SpiderOak was rated "Awesome" by MacLife magazine in 2009[9] and also was made an Editor's Choice by Computer Shopper magazine in May 2009.[10]

Main features[edit]

  • All data accessible in one de-duplicated location
  • Configurable multi-platform synchronization
  • Preserve all historical versions and deleted files
  • Share folders in web ShareRooms with RSS notifications[4]
  • Retrieve files from any internet-connected device
  • "Zero-knowledge" data encryption if you only use the desktop client (no sharing, web-access, or mobile access)
  • Unlimited devices[11]
  • A layered approach to encryption, using a combination of 2048-bit RSA and 256-bit AES.[6]
