## Introduction

This is the LAMP / LEMP environment backup guide in case you want or need to try my [highload LEMP installation](https://github.com/sutlxwhx/highload-lemp-installation).

## Basic usage

As a first thing we will setup a variable that will store current date and time. We will use year-month-day_hours-minutes-seconds format:
```shell
now=$(date +"%Y-%m-%d_%H-%M-%S")
```
Then we need to create a folder where Nginx configuration files will be stored:
```shell
mkdir /backup/$now/nginx/
```
We will repeat previous step for your PHP installation:
```shell
mkdir /backup/$now/php/
```
If you already have MySQL or MariaDB installed do this step too:
```shell
mkdir /backup/$now/mysql/
```
This is the main backup process, just copy files from one folder to another.
<br/> For Nginx:
```shell
cp -r /etc/nginx/ /backup/$now/nginx/
```
For PHP:
```shell
cp -r /etc/php/ /backup/$now/php/
```
For MySQL / MariaDB:
```shell
cp -r /etc/mysql/ /backup/$now/mysql/
```
