WordPress backup to Yandex Cloud: mysqldump, rclone, and Telegram notifications

2025-10-15

Running a site on WordPress is great, but data reliability and security are a priority. Regular backups protect the project from errors, attacks, and failures. In this guide we’ll look at how to create an automatic WordPress backup using:

• mysqldump — for the database,
• rclone — for uploading to Yandex Cloud,
• curl — for notifications in Telegram.

🛠️ Step 1. Creating a Local Backup

1.1 Checking WordPress Configuration

The wp-config.php file is located in the site root (/var/www/ваш_сайт/wp-config.php):

Loki + Grafana: A Lightweight and Cost-Effective Logging Solution for the Cloud

We’re wrapping up our series on centralized logging with a modern and innovative solution: Loki together with Grafana. Developed by Grafana Labs, this stack reimagines how logging works — making it simple, efficient, and especially appealing for those already using Prometheus.

What Is Loki and How Does It Work?

Loki is a log aggregation system designed to minimize resource usage. It indexes only metadata (labels), while the log messages themselves are stored in compressed form — following the same philosophy as Prometheus, but for logs.

054 | VictoriaMetrics + Grafana: Efficient Time-Series Storage for Scalable Monitoring

2025-07-16

In our series on monitoring systems, we’ve reviewed Munin, Prometheus with Grafana, and Zabbix. Now it’s time to talk about a solution that addresses one of the main pain points of Prometheus users — long-term, scalable, and efficient time-series storage. Meet VictoriaMetrics, a high-performance and cost-effective TSDB (time-series database) that perfectly complements the Prometheus ecosystem when paired with Grafana for visualization.

What Is VictoriaMetrics and Why Do You Need It?

Prometheus handles real-time monitoring and storage well, but its built-in TSDB isn’t designed for long-term retention or scaling to terabytes or petabytes of data. That’s where VictoriaMetrics comes in.

052 | Prometheus + Node Exporter + Grafana: The De Facto Standard for Cloud Environments

2025-07-14

We’ve reviewed Munin as a simple solution for basic monitoring. Now let’s move on to a stack that has become an indispensable tool in the world of modern cloud infrastructure, microservices, and containers: Prometheus, Node Exporter, and Grafana. This trio provides a powerful, flexible, and scalable approach to collecting, storing, analyzing, and visualizing metrics.

What is Prometheus and Its Ecosystem?

Prometheus is an open-source monitoring system originally developed at Google and later handed over to the Cloud Native Computing Foundation (CNCF). Its key feature is the “pull” model: Prometheus scrapes metrics from targets via HTTP endpoints.
