Cloud storage is nothing but an enterprise-level cloud data storage model to store the digital data in logical pools, across the multiple servers. You can use a hosting company such as Amazon, Google, Rackspace, Dropbox and others for keeping your data available and accessible 24×7. You can access data stored on cloud storage via API or desktop/mobile apps or web based systems.


In this post, I’m going to list amazingly awesome open source cloud storage engines that you can use to access and sync your data privately for security and privacy reasons.

  1. Create a cloud on your own server or in a data center.
  2. Control and own your own data.
  3. Privacy protection.
  4. Encryption.
  5. Verify source code for bugs and/or backdoors.
  6. Avoid spying on your files on the server using encryption.
  7. Legal compliance – HIPAA and others.
  8. Good performance as your data stored in local storage instead of remote data center.
  9. Good reliability and availability due to local LAN. You are no longer depends upon WAN bandwidth or the service provider for network.

You can use the Raspberry Pi or an Intel Atom CPU based small server as a home cloud storage system. Use an external USB drive or secure backup service such as rsync.net/tarsnap.com to backup your cloud server in an encrypted format. This setup ensures that you keep all your data and not to trust the entirety of your personal data to a corporation.

Personally, I’m using Owncloud as FOSS based cloud solution for my file sharing with friends and family. It offers me Calendar, Contacts, and Dropbox like storage. My cloud server has total 5 disks, 2 Gib RAM, and an Intel atom cpu. I use a Debian Linux with RAID 6. I backup my cloud to an external USB drive and currently, testing tarsanp backup service. I’m also planning to try out SparkleShare on the Raspberry Pi soon.

Are you using any other personal FOSS cloud basesd software? Add your suggestions the comments below.
