Seeking advice on OS migration for my Lenovo Mini PC home server
Hi everyone,
I’m currently using a mini PC as my "everything" server, but I’m hit a crossroads regarding data safety. Here’s my current setup:
• Hardware: Lenovo M910q (i5 6500T, 16GB RAM)
• Storage: 256GB M.2 SSD (boot/apps), 512GB + 1TB 2.5" HDDs, and a 1TB 3.5" HDD via an Axagon dock.
• OS: Headless Ubuntu.
Almost everything is running in Docker (except for Samba for network shares). My stack currently includes:
Caddy, Plex, multiple web servers + backends, Torrent, Kasm, Portainer, Grafana, Uptime Kuma, cAdvisor, Cloudflare, MySQL, Postgres, Paperless-ngx, phpMyAdmin, AdGuard Home, Wg-easy, and Home Assistant.
The problem:
Currently, I have zero parity, and I’m starting to get nervous about potential data loss. I’m considering switching to a dedicated "all-in-one" OS that simplifies management but still leaves room for experimentation.
What I'm considering:
• ZimaOS: Is it actually too "dumbed down" and oversimplified?
• OMV (OpenMediaVault): A solid contender.
• TrueNAS: Would my hardware be too weak for this? I've heard it can be quite resource-heavy.
• Unraid: Honestly, it feels a bit too expensive for my budget.
• Staying with Ubuntu: Just adding SnapRAID + MergerFS to the existing setup.
What would you recommend? Should I stick to my DIY Ubuntu setup or jump ship to a dedicated NAS OS? Thanks for the advice!
