This Bundle provides a backend module to easily create and list backups of the contao database. The backups can be downloaded in the backend and backups can be created manually by backend users.

Please read the migration notes from version 1 below! The console command bwein:database:backup and cronjob listener were removed from the extension in version 2 because Contao 4.13 includes a backup command - see:


Install the bundle via Composer:

composer require bwein-net/contao-database-backup


In the config/config.yml you can add the following optional parameters:

# config/config.yml
    cron_interval: 'daily'

The default of cron_interval is null - so no cron job is running. You have to define it manually - see:

The option cron_interval can be minutely, hourly, daily, weekly, monthly, yearly or a full CRON expression, like */5 * * * * - see:

Attention: Even if you define daily as cron_interval you need to specify the keep_max and keep_intervals of the core to have daily backups e.g.

# config/config.yml
    keep_max: 10
    keep_intervals: ['1D', '2D', '3D', '4D', '5D', '6D', '7D', '14D', '1M']

Migration from version 1 to 2

Replace Configuration

The custom configuration bwein_database_backup has to be removed from config/config.yml. Optionally, it can be replaced by the core configuration - see:

Run Migration

The existing backups will be automatically moved from var/db_backups to var/backups with a migration by running contao:migrate or use the Contao Install Tool.

Change backup directory

If you use deploy tools like deployer that define shared dirs, you need to change the backup directory from var/db_backups to var/backups!

Add Cronjob

The cronjob listener has been removed so you have to add a manual daily routine:

0 4 * * * /path/to/system/vendor/bin/contao-console contao:backup:create


Replace command usages

The command bwein:database:backup has been removed so you need to replace the usages to contao:backup:create - see:
