README

Backup and Restore functionality for Yii2 applications.

This extension is based on:

I combined those sources and made a more powerful and easier to use extension.

Supported databases:

  • MySQL
  • MariaDB (via MySQL driver)
  • SQLite
  • PostgreSQL

Supported compression methods:

  • Bzip2
  • Gzip
  • Zip

By default the backup files is a tar file with sql dumps and folders.

Current limitations:

  • Requires a linux system.
  • Currently only MySQL on localhost is supported.
  • Currently only MariaDB on localhost is supported.
  • Currently only PostgreSQL on localhost is supported.

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist amoracr/yii2-backup "*"

or add

"amoracr/yii2-backup": "*"

to the require section of your composer.json file.

Once the extension is installed, add it in your config file:

Basic config/console.php

Advanced console/config/main.php

Minimal Config

'components' => [
    ...
    'backup' => [
            'class' => 'amoracr\backup\Backup',
            // Path for storing the backups
            'backupDir' => '@app/backups',
            // Directories that will be added to backup
            'directories' => [
                // format: <inner backup filename> => <path/to/dir>
                'images' => '@app/web/images',
                'uploads' => '@app/web/uploads',
            ],
        ],

                // Key 'path' for setting the directory to include
                // Key 'regex' for setting the regular expression for selecting the files to include
                'pdf' => [
