# Quick Start - End-to-end Backup and Restore

Part of the doc set: [SL Migrations](https://phatdev.net/en/docs/sl-migrations.md)

> The full workflow from creating a backup to a successful restore on a new server.

## Quick Start

A quick guide from creating a backup → downloading it → restoring it on a new server.

## Step 1: Destination server requirements

| Component | Minimum | Recommended |
|---|---|---|
| PHP | 7.4 | 8.0+ |
| MySQL/MariaDB | 5.6 | 5.7+ |
| Free disk | 2× the site size | 3× to leave room for extraction |
| Memory limit | 256 MB | 512 MB+ |
| Max execution time | 60s | 300s+ |
| PHP extensions | zip, openssl, mbstring | all of them |

## Step 2: Create the backup on the source site

In the WordPress admin of the source site:

1. **SL Migrations → Packages → Create New**
2. Name the package → **Next**
3. **Scanner** checks the environment - review the warnings and fix any errors
4. **Build** - the plugin compresses the files and dumps the database
5. When the build finishes, download both files: the **archive** and **installer.php**

## Step 3: Prepare the destination site

- Create an empty database on the destination server
- Create a database user with full privileges (`ALL PRIVILEGES`) on that database
- Note down the host / database name / username / password
- Make sure the web root folder is empty or contains only the installer file (the safest approach)

## Step 4: Upload and run the installer

Upload `installer.php` and the archive file to the destination site's web root (via FTP, SFTP, cPanel File Manager or rsync). Then open:

```
https://site-dich.com/installer.php
```

The installer runs through 4 steps:

1. **Deployment** - choose how to extract the archive
2. **Install Database** - enter the database details you prepared
3. **Update Data** - the installer replaces the old URL with the new one
4. **Test Site** - check that the new site is up and running correctly

## Step 5: Clean up after installing

After step 4 reports success, the installer **deletes itself**, along with the archive, logs and temporary files. Check the web root folder again to make sure nothing is left behind - see the [list of files to remove](https://phatdev.net/en/docs/sl-migrations/which-files-need-to-be-removed-after-an-install).
