    • If you just upload your files to Google Drive, two things happen: 1) you can sync them across different computers and access them from your Google/Gmail account, 2) they are stored on Google's servers in a way that Google can scan them and have access to their content. Spideroak allows you to backup AND sync your files, but in a way that your files and their contents are only accessible to you, no one else.

    • 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.

    • 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).

    • OneDrive is bundleware integrated into MS Windows. It seeks to "help" you by syncing your files, even every MS Office document you write by default. (Switch that off!) It's intrusive, and it seeks to upload unencrypted versions of your files to MS servers. SO is a privacy-oriented company that encrypts your files in a way that makes them accessible only to you. Both sync your files, but SO respects your privacy. There also isn't a Linux sync agent for OD.

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.
