Alternatives to SpiderOak for all platforms with Free License

Dropbox

Worlds leading online storage and file sync service. You get 2GB free. Apps for all major platforms.
- Spideroak both syncs AND backs up your files. Dropbox is not a backup service. Most importantly, Spideroak encrypts files on your computer before uploading them to their servers, which means only you can see your files and no one else. Dropbox doesn't do this, which means that Dropbox employees could access your files, which a much less private solution. Guest • Nov 2016 • 15 agrees and 0 disagrees
- Dropbox is not a good SpiderOak alternative because: 1) It doesn't offer end-to-end encryption and the privacy advantages that offers (that's a big deal), 2) it's emphasis is on sync, SpiderOak offers sync and backup. Dropbox has been reported to be an NSA surveillance target; SpiderOak has no such concerns because of its encryption system. Parts of SO are open source.

- 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. JohnFastman • Dec 2016 • 10 agrees and 0 disagrees

ownCloud

A safe home for all your data – Access & share your files, calendars, contacts, mail & more from any device, on your terms.
- 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. JohnFastman • Dec 2016 • 3 agrees and 0 disagrees

- 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). JohnFastman • Dec 2016 • 4 agrees and 0 disagrees

Microsoft OneDrive

Get to your files from anywhere, on any device, with Microsoft OneDrive. Share and work together with anyone in your work and life.
- 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. JohnFastman • Dec 2016 • 6 agrees and 0 disagrees

Resilio Sync

Resilient, fast and scalable file synchronization for enterprises and individuals.
- Resilio sync is for syncing, not for backup; SpiderOak is for both. Also, SpiderOak encrypts files on your computer before they get uploaded, so it offers that much more privacy out of the box. Resilio Sync will sync files MUCH faster, but should not be relied on for backup because you need a computer running all the time to use it. Check out SyncThing as an open-source and more trustworthy alternative to Resilio Sync. JohnFastman • Feb 2017 • 3 agrees and 0 disagrees

pCloud

pCloud is your personal online storage space for your memorable photos and videos, your favorite music or important work documents.
- 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. JohnFastman • Dec 2016 • 1 agrees and 1 disagrees

Librevault

Librevault is an open-source peer-to-peer file synchronization program, designed with convenience and privacy in mind.
- Discontinued The project seems to be abandoned since March 2017. Latest version, v0.1.19, released in October 2016, can be still downloaded from the official website.
- Librevault aims at secure and very fast transfer of files between two computers. It does this without a server in the middle via a peer-to-peer system. It's not at all well suited to backups, which is what Spideroak does primarily. Guest • Nov 2016 • 2 agrees and 0 disagrees
