Latest news from the world of IT. TrueNAS, Proxmox, OPNsense and more.
TrueNAS Spotlight: Full-Text Search and Search Index on the NAS
TrueNAS 26.04 brings a Search Index with full-text search across file names and content. How Apache Tika and Lucene work together, which use cases pay off, and what to watch for on privacy and resource consumption.
Server Room Energy Costs: 5 Levers
Save energy in the server room without new hardware. Five concrete levers: hot-aisle / cold-aisle separation, server power profiles, idle VM consolidation, UPS efficiency, and right-sized cooling. Plus: when ARM / EPYC hardware pays off.
OPNsense for Medical Practices: What German KBV Requirements Demand
German KBV requirements for medical practice networks demand network separation, firewall logging, and defined TI connections. OPNsense implements this with VLANs, firewall rules, and Suricata. Important: TI connector certificates are separate from OPNsense — OPNsense complements TI security, it does not replace it.
Backup Test Day: Prove Restores in 30 Minutes
A backup that hasn't been tested is hope. We describe the Backup Test Day workshop format — monthly, 30 minutes per restore scenario, with checklists for PBS VM restore, TrueNAS snapshot restore, M365 restore, and tape restore. Includes the documentation obligations under NIS2 and German GoBD.
Caddy: Reverse Proxy With Automatic HTTPS
Caddy is a modern reverse proxy with built-in Let's Encrypt automation. Ten lines of Caddyfile instead of fifty lines of Nginx — and no certbot. We show setup, examples for three self-hosted services behind one public IP, and the limits compared with Nginx.
TrueNAS for Tax Advisors: GoBD-Compliant Data Retention
German GoBD rules require immutability, completeness, traceability, and 10-year retention. TrueNAS provides technical building blocks with ZFS snapshots, replication, and integrity checks — but on its own it is not GoBD compliant. We show the architecture that works in tax advisory practices.
Ransomware 2026: Current Trends and Concrete Protection Measures
Ransomware remains the most expensive cyber threat for SMBs and mid-market. We frame the 2026 threat landscape — Big Game Hunting, Double Extortion, Data-Theft-Only — and describe a seven-layer protection model built from patch management, MFA, EDR, segmentation, air-gap backups, immutable snapshots, and an IR plan.
Restic: Encrypted Backups, Explained Clearly
Restic is a lean, cross-platform backup tool with deduplication and at-rest plus in-flight encryption. We cover the architecture, repos on TrueNAS, B2, and SFTP — including snapshots, pruning, and restore.
ZFS AnyRaid: Pools From Mixed Drive Sizes, Finally
AnyRaid in OpenZFS 2.4 (TrueNAS 26 Halfmoon) solves the classic mixed-drive problem in ZFS. Until now ZFS used only the smallest drive size per VDEV — AnyRaid uses every available block. What it is technically, when it fits, and which limitations remain.
Self-Hosting vs. Microsoft 365: When Running Your Own Servers Pays Off
Microsoft 365 or a self-hosted mail, file and collaboration stack? An honest comparison matrix for SMBs — when self-hosting really pays off, when M365 is the rational choice, and how hybrid setups work in practice.
OpenZFS 2.4: What Users Will Actually Notice
OpenZFS 2.4 in TrueNAS 26 and upcoming distributions: AnyRaid for mixed drives, Block Reference Table for fast clones, dRAID stability, RAIDZ expansion maturity. A pragmatic look at what becomes noticeable in daily operations — and what does not.
Proxmox Backup Server 4.0: What Has Changed Since 3.x
Proxmox Backup Server 4.0 is based on Debian 13 Trixie, Linux 6.x and ZFS 2.3. Synthetic backup, mountpoint backup, tape improvements and S3 object store targets in the pipeline. What actually changed compared to PBS 3.x — sober, from the official release notes.
