SpiderOak for Windows

SpiderOak is a cloud-based service that combines online backup, file sync, and easy sharing. Desktop clients are available for Windows and Mac OS X, as well as multiple Linux distributions. After account creation, several gigabytes of storage are available for free. You can upgrade to a 100+GB monthly or annually for an additional fee. SpiderOak combines several functions into one tool: remote access, free online backup, remote synchronization, sharing, and storage. Backups can be performed from both local hard-drives and external hard-drives. All data is encrypted and transmitted encrypted over a secure SSL connection to prevent third party access. All these features are available both for the free and subscription service.
