Running natively on Mac OS X, Windows, and Linux, SpiderOak allows users to create a central storage repository where they can access data from all their SpiderOak devices within the application, or via Web login at SpiderOak.com.

Using an automated approach, SpiderOak immediately backs up and stores any additions, edits, or changes to the back up set. Historical versions of any document can be identified and downloaded by timestamp.

Any folders within a user's SpiderOak account can be selected for sharing in a password protected setting called a 'ShareRoom', and any changes or additions to the shared folders are automatically seen by visitors to the ShareRoom.
