To add a new device to your SpiderOak account, download and install SpiderOak on the computer you wish to add. During setup, choose the option to "Add a New Device." This device will now go through syndication, which means SpiderOak is downloading the necessary data about your account from our servers. No files from your other devices will be downloaded or synced to this computer during setup.
Once syndication completes, you're ready to begin selecting your data for backup.
