Clonezilla LUKS2 Backup Repositories: A Weekly Capacity Checklist

Nov 12, 2026    Mariusz Antonik    Automation    10 min read

Encrypted image repositories make bare-metal recovery safer, but encryption does not protect them from capacity drift, failed mounts, or incomplete retention. This practical checklist shows how to monitor LUKS2-backed Clonezilla storage, estimate growth, verify usable backups, and preserve recovery headroom. It also covers HTTP Boot infrastructure and the operational checks that matter after a deployment-tool upgrade. Use it as a focused Linux server monitoring routine for imaging environments without adding another dashboard.

How Long Should You Keep an Old Linux Server? A Decommissioning Checklist

How Long Should You Keep an Old Linux Server? A Decommissioning Checklist

Nov 04, 2026    Mariusz Antonik    Automation    8 min read

Keeping a retired server indefinitely feels safe, but it often preserves uncertainty rather than reducing risk. A short, evidence-based rollback window is usually more useful than a machine gathering dust for years. This checklist covers migration validation, Linux server monitoring, data sanitization, resale, recycling, and the records a small business should retain. It also provides a practical timetable for deciding when old hardware can leave the building.
