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.
NIS2 for SMBs: Which Obligations Actually Apply in 2026
Germany's NIS2 implementation act: who is in scope, which eleven minimum measures from Article 21 must be implemented, which reporting deadlines apply, and how does management liability work? A practical overview without marketing fluff.
VMware License Costs 2026: What SMBs Actually Pay
Broadcom has rebuilt the VMware licensing model: mandatory bundles, minimum core counts, subscription instead of perpetual. What this means for SMBs in 2026 — patterns from DATAZONE consulting, realistic alternatives, and a decision matrix.
TrueNAS 26 Beta: The Key Changes for SMB Environments
TrueNAS 26 'Halfmoon' Beta has landed — with OpenZFS 2.4, ransomware detection, a reworked WebShare and a new alert system. What it means for SMBs, when the beta is worth testing, and when to wait for the final enterprise release.
