DIY Data Defense: Building Your Own Encrypted Cloud Storage Solution

We believe in data soverignty at Secret Chest. That means the Web 3 style social media approach to some or the idea of being able to opt out of data collection and privacy to others. Still many who take either approach will host files in a public cloud because it’s easy, or because that’s the only way they can think to do it.

Reclaiming control over your digital life can be seen as an act of rebellion to some. Not to us. To us it’s about a concious choice. Where do you want each type of data and why? We’re not out to ditch the clouds of tech giants and forge our own path to data sovereignty - in fact, we have most of our stuff in public clouds (all with DPAs if you’re in the compliance space). This guide will take you through building your own encrypted cloud storage solution, a digital fortress where your precious bytes reign supreme.

Why DIY? The Allure of Self-Hosted Security

Imagine a sanctuary beyond the prying eyes of algorithms and intrusive data policies. In your self-hosted cloud, you are the king, the gatekeeper, the sole arbiter of who accesses your digital domain. The benefits are intoxicating:

  • Unwavering Encryption: Forget opaque algorithms and black-box cloud services. Choose your encryption, configure its strength, and relish the transparency of knowing your data is locked tighter than Fort Knox.

  • Privacy, Redefined: No more surrendering your data altar to hungry corporations. Own your privacy, control your metadata, and enjoy the peace of mind of knowing your digital life is truly yours.

  • Customization to the Core: Tailor your cloud to your unique needs. From storage size and user access to plugins and themes, your cloud reflects your digital footprint, not someone else's algorithm.

  • Financial Freedom: Break free from the shackles of monthly subscriptions. Invest in hardware once, reap the benefits for years, and watch your wallet sigh with relief.

The Tools of the Trade: Nextcloud vs. ownCloud

Navigating the self-hosted cloud landscape can be daunting. Fear not, intrepid explorer! Two open-source platforms stand tall: Nextcloud and ownCloud. Both offer robust features and passionate communities, but here's a lowdown to help you choose your digital haven:


  • Strengths: Intuitive interface, vast app ecosystem (music streaming, collaborative editing, calendar apps, etc.), strong mobile apps, active development community.

  • Weaknesses: Steeper learning curve, resource-intensive, smaller user base compared to ownCloud.


  • Strengths: Easier to set up, lighter on resources, larger user base and documentation pool, mature and stable codebase.

  • Weaknesses: Less intuitive interface, limited app ecosystem compared to Nextcloud, less frequent updates.

The Quest Begins: Step-by-Step Guide to Building Your Fortress

Now, grab your digital sword and prepare for battle! This guide, tailored for both Nextcloud and ownCloud, demystifies the setup process, leading you step-by-step to your sovereign data haven:

1. Choose Your Weapon: Server and Software

  • Hardware: Select a dedicated server or repurpose an old PC (minimum 4GB RAM, 1TB storage). Raspberry Pi enthusiasts, rejoice! You can use a Pi 4 with external storage for a mini-cloud solution.

  • Software: Download the desired platform (Nextcloud or ownCloud) from their official websites.

2. Forge Your Stronghold: Installation and Configuration

  • Server Installation: Follow the platform's installation guide for your chosen operating system (e.g., Ubuntu, Debian). This typically involves downloading server files, running commands, and setting up the database.

  • Web Interface: Access the platform's web interface via your server's IP address and browser. Set up your admin account and configure basic settings like language and time zone.

3. Build Your Defenses: Security Measures

  • Strong Passwords: Choose complex, unique passwords for your admin account and user accounts. Consider two-factor authentication for added security.

  • HTTPS & Firewall: Enable HTTPS for secure web access and configure your server's firewall to restrict access to authorized IPs and ports.

  • Regular Updates: Keep your platform and server software up-to-date to patch vulnerabilities and improve security.

4. Stock Your Armory: Customizations and Apps

  • User Management: Create user accounts for family, friends, or colleagues and assign appropriate access levels and storage quotas.

  • Apps and Plugins: Extend your cloud's functionality with apps for file sharing, collaboration, calendar, music streaming, and more. Nextcloud boasts a wider app ecosystem, while ownCloud offers a curated selection.

  • Themes and Tweaks: Choose a theme that suits your aesthetic and configure additional settings to personalize your cloud experience.

5. Troubleshooting: When the Dragon Attacks

No quest is without hurdles. Be prepared to tackle these common issues:

  • Installation errors: Consult the platform's documentation or community forums for specific troubleshooting steps.

  • Web interface not accessible: Verify server ports are open and firewall rules are correct.

  • Performance issues: Optimize server resources or upgrade hardware if necessary.

  • Data Loss: Regularly back up your data to avoid potential loss caused by server

Overall, this is a bit of a pain and the quality isn't as good as using public clouds at this very second. But it's great to have options, and to know what projects to follow for a time when they do catch up with plenty of public cloud options!
