The Problem

Self-hosters running databases, Docker containers, and media servers on home hardware rely on manual, ad-hoc backup processes that inevitably fail. They forget to run backups, don't notice when backups silently break, and have never tested whether their backups actually restore — leaving them one disk failure away from total data loss.

Potential Solution

A lightweight agent that runs alongside self-hosted services, auto-discovers Docker volumes and databases, and handles scheduled incremental backups to multiple destinations (local drives, cloud storage, remote servers). It includes built-in restore verification that periodically spins up a test container from the latest backup and confirms data integrity, sending clear pass/fail alerts.

Why Now?

Self-hosting is surging as users move away from cloud subscriptions for privacy and cost reasons, but the tooling for reliable home-server operations still lags far behind enterprise solutions. The proliferation of Docker-based deployments creates a standardized target for backup automation that wasn't feasible when setups were more heterogeneous.

Mastering Object Storage for System Design Interviews
Apr 30, 2026

The provided text explores object storage as a specialized system for housing large, static files known as blobs, such as videos and high-resolution images. Unlike relational databases, which struggle with the performance overhead and backup delays caused by massive files, object storage uses a flat namespace and immutable writes to ensure efficiency. Key industry standards include using a traditional database for metadata while storing the actual content on cheap, redundant storage nodes to achieve high durability. [Object Storage](youtu.be/.../wJWlWzwaBuU) Advanced techniques like pre-signed URLs allow clients to bypass application servers for direct uploads, while multi-part uploads enable the handling of massive files by breaking them into smaller chunks. Ultimately, the source highlights tools like Amazon S3 as essential components for maintaining speed and scalability in modern system design.

I built something for devs tired of cloud pricing. StorForge: • S3-compatible storage • 500GB for $1.50/month • Works with rclone, SDKs, existing tools • Encrypt before upload (you keep the keys) No ecosystem lock-in. No pricing games. storforge.io

AWS S3 pricing pushed me to build this. StorForge: • S3-compatible • \~$3/TB • No lock-in • Use your existing tools • Encrypt your data before upload Early access: storforge.io

I got sick of AWS S3 egress fees and 5TB limits, so I built a storage system with $0 BOM cost and It holds 5 Exabytes per instance.
Apr 30, 2026

Hey everyone, I’m Adarius, founder of Vader Technologies. I’ve been watching AI startups and creative platforms bleed cash because of three things: massive duplicate file uploads, version mismatches across devices, and skyrocketing S3 compute/egress costs just to keep their workspaces from lagging. The current infrastructure is basically a tax on inefficiency. So I built something else entirely. I call it VAULT 33. It’s a fully digital, invisible storage system that operates without a traditional database. 1. Zero Duplication Ingestion: Data is ingested once. If a user uploads the same file or link, it creates an automatic reference instead of duplicating the data. Compute costs drop instantly. 2. No Artificial Limits: Instead of capping users at 100GB or 5TB, one instance has an effective capacity of 5 Exabytes. 3. Instant Reproduction: It uses bit-perfect reproduction, meaning zero data loss and perfect sync across devices without version mismatches. 4. Transportable: The entire vault can be exported as a single compact artifact, moved anywhere (cloud, edge, air-gapped), and deployed in under 60 seconds. I’m currently looking for my first pilot partner (a startup dealing with heavy storage/egress pain) to license it for a 90-day test run to prove the cost savings in a live environment. Reach out!

fractalbits: The ultimate S3 compatible high performance object storage in the AI era, supporting both actix & axum, using rust + zig
Apr 30, 2026

Hi all, today I am pleased to open source the fractalbits api\_server, supporting both **actix & axum** framework. FractalBits is an S3-compatible object storage system designed for high performance and low latency. Using our custom-built metadata engine, it delivers up to 1 million 4K read IOPS for single bucket with p99 latency \~5ms, at significantly lower cost than AWS S3 Express One Zone. Unlike standard S3, FractalBits provides native atomic rename support for both objects and directories. Our storage engine is implemented with Zig, for its simpler io\_uring programming model and easier customized memory allocators. We are not open sourcing those parts yet, since the language is still moving to new async IO APIs. However, you can check how we make the two languages get along with each other well by checking our high performance rpc framework if interested. Other than that, We are basically **using rust to manage almost everything for our project**: build, dev env setup, testing setup and running, and also cloud deployments, without using a single line of shell script! Our repo link is below, and welcome to have a try and leave any feedback. I will also be pleased to answer any related questions: [github.com/.../fractalbits-main](github.com/.../fractalbits-main)

HS5 - Open Source fast single-node S3 compatible object storage
Apr 30, 2026

HS5 is a high-performance scale-up self-hosted S3 compatible object storage server. It is ideal for use cases where single-node scaling, performance, and data-loss risk are acceptable. So for some self-hosting use cases it might be great. I actually see recent (the last one 20h ago) posts here where it might be a fit for the use case. HS5 features a web interface for managing buckets and users. I was previously using MinIO for my single node object storage needs, but it did not scale well with many objects since it creates multiple files for each object. Now it does not aim to solve the single-node use case anymore anyway and is unmaintained as well. Feedback welcome! Website: [hs5.eu](hs5.eu) Github: [github.com/.../hs5](github.com/.../hs5)
