    • ownCloud is a PARTIAL SpiderOak alternative. Through oC's client you can backup and sync files. Typically, oC is run on your own server. This means only your hard disk limits the storage space, and your files belong to you. But oC doesn't encrypt your files in the "zero-knowledge" way, which SpiderOak does. SO costs money; oC doesn't unless you get a hosted version. Use oC with Cryptomator to maximize privacy/security. JohnFastmanDec 2016 Disagree   Agree

    • MEGA is similar to SpiderOak because it claims to encrypt your files locally before upload and not have the keys to decrypt them ("zero-knowledge"). However, since its inception, MEGA has been mired in various controversies and has had security flaws detected (since fixed). SO has enjoyed a solid reputation. Both MEGA and SO can become slow when dealing with large numbers of files (not necessarily large files). JohnFastmanDec 2016 Disagree   Agree

    • Tresorit is probably the best SO alternative, but it's also very expensive. Like SO, Tresorit is a company offering secure, end-to-end encrypted sync (which you can use as backup too). Files are encrypted on your computer and you hold the keys. Neither SO nor Tresorit can read your files. Tresorit is based in Switzerland, with stricter privacy laws. Both are Mac, Win and Linux friendly. JohnFastmanDec 2016 Disagree   Agree

    • pCloud are a Swiss (strong privacy laws) hosted sync service, similar to Dropbox. They are a partial SpiderOak alternative because they offer the option to have an encrypted folder to which only you have the password, and the contents of which only you can read. That is SpiderOak's whole way of working, so pCloud are a partial alternative. Uploads/Downloads are very fast though. Also Linux-friendly. JohnFastmanDec 2016 Disagree   Agree
