Cloudflare Tunnel vs Tailscale vs WireGuard vs NetBird: Which Remote Access Tool Fits?
Choose remote access by users, services and operating responsibility. Compare private overlays, managed or self-operated keys and published web paths, keeping authentication and authorization separate from the encrypted tunnel.
How Do You Make DNS Keep Working When the Internet Is Down?
Serve local names without depending on a public resolver, and plan resolver-host resilience separately from WAN resilience. Test real client paths while recognizing that local DNS cannot replace cloud authentication or uncached public answers.
OPNsense, pfSense, UniFi, or Consumer Router: Which Should Run Your Homelab?
Compare router platforms by ISP requirements, policy, VPNs, enabled-feature workload and recovery. Evaluate exact models and releases rather than treating a dashboard, feature list or integrated management as proof of throughput or isolation.
What Is the Right VLAN Layout for a Beginner Homelab?
Build a small set of explainable trust zones with explicit firewall, DHCP and DNS plans. Keep experimental workloads separate from infrastructure management when their access needs differ, and preserve a recovery path.
2.5GbE vs 10GbE: Which Home Network Upgrade Is Worth It?
Keep existing Ethernet when it meets the workload. Compare 2.5GbE and 10GbE against measured client, storage and uplink bottlenecks, then check exact cabling, port support and cooling before buying.
How to Build Cheap Offsite Backup at a Friend or Family Member's House
Plan encrypted offsite backups at a consenting household through a private tunnel, with agreed transfer limits and independently stored keys. Test recovery over the real connection; encryption alone does not prevent deletion.
One Shared Database Server or One Database Per App?
Choose shared or per-app databases by engine compatibility, maintenance needs and failure boundaries. Separate application credentials in either design, and account for shared downtime and post-cutover writes before consolidating.
How Do You Back Up Docker Volumes and Databases Properly?
Back up Docker by backing up the data, configuration, and restore instructions, not the running container. For databases, use application-aware dumps or backup tools, then store those dumps with the volume backups.
RAID, ZFS Snapshots, Sync, and Backup: What Each One Does Not Protect
Choose storage protection by failure mode: RAID for certain disk failures, snapshots for point-in-time state, sync for current changes and independent backups for recovery. Not every design needs all four.
How Much Does a Homelab Really Cost in Electricity?
Estimate homelab electricity costs from representative energy use and the applicable tariff. Define the meter boundary so networking equipment, storage and UPS losses are counted once rather than overlooked or duplicated.
