A retention policy is a storage multiplier, and on a budget VPS the multiplier usually costs more than the plan. Daily backups kept for 30 days sound modest until you count the weekly and monthly copies layered on top, and…
The OOM killer is not a bug in Docker. It is the kernel enforcing a limit you set — or forgot to set. On a 1–2 GB budget VPS, the difference between a stable container host and one that dies…
On a 1 GB VPS running nginx and PHP-FPM, the single most consequential number in the entire configuration is pm.max_children. Set it too low and requests queue behind a busy worker while the CPU sits idle. Set it too high…
A Node.js application needs far less memory than most sizing guides imply, but it needs it in a specific shape: a fixed per-process floor of roughly 50–80 MB for the runtime, plus memory proportional to concurrent requests, plus a heap…
Most self-managed VPS backup failures have the same root cause: the backup runs on the same disk it is meant to protect, or it is retained for a period nobody ever chose deliberately. A backup strategy is really two decisions…
Every Linux release reaches end-of-life on a published date, and on that date the security patches stop. For a budget server the interesting question is not whether to upgrade but when: do it early and you burn a weekend on…
Log retention is the cheapest-looking line item on a budget server and one of the most common causes of an unplanned upgrade. The mechanism is predictable: a service logs at a volume nobody measured, retention is left at a default…
The figure that decides the bill is not the 1 TB “1 TB of images” sounds like a single number, but the annual bill depends on how those bytes leave the server, how many times they leave, and whether anyone…
Why the DNS cut is the wrong time to find out A DNS change propagates unevenly, and reverting takes as long as the original switch. Everything that can be verified on the new box under its temporary hostname should be…
Traefik and Caddy both terminate TLS, route by hostname, and run in containers — and both claim to be “lightweight.” On a $5 VPS the difference matters: a reverse proxy that idles at 150 MB leaves you 850 MB for…
