Let's learn more about the DbToolsBundle with 3 use cases that it addresses:

Use case 1 - Dealing with backup (and restoration) in a delivery workflow

During your project life cycle, you will need to deploy new versions on one or many production environments. We all know that we can't prevent problems to happen, that's why, ideally, you always backup your database before upgrading.

Get this task done quickly with:

console db-tools:backup

DbToolsBundle will call the right backup program (pg_dump, mysqldump or other) with the correct parameters. At the end of the process, it will give you the opportunity to clean old backups from your disk.

Now, let's say that your migrations were not so robust and something bad happened during your deployment, something really bad... You can't fix it quickly, so you decide to rollback for now.

Simply run:

console db-tools:restore

This command will list you all backups available on your disk. Choose the one you want to restore!

These commands are only kinds of shortcut for pg_dump/pg_restore or mysqldump/mysql but much more handy to use. They find the correct binaries and execute them with the correct options for you.

Use case 2 - Anonymizing production data to use them on your local environment

You need to retrieve data from your production environment, but you don't want to have sensitive data on your local environment.

Let's say you have launched a console db-tools:backup on your production environment and downloaded the backup file on your machine.

You could run console db-tools:restore to populate your database from the freshly downloaded backup file. But in doing so, you will end up with sensitive data on your machine, which is not what you want:

  • First of all, because in most cases that's illegal (in UE for example, because of GDPR).
  • Secondly because you just don't want to know personal data from your clients or your client's clients.

To avoid that, you need a proper anonymization.

As it could be tricky and time-consuming to try to nicely anonymize data: the DbToolsBundle get rid of that for you.

With the DbToolsBundle, by adding some PHP attributes on your Doctrine Entities, you can easily configure a complete anonymization for your sensitive data.


Anonymization does not only work with Doctrine Entities. You can use it with any database and configure it with YAML. All you need is a DBAL connection.

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use MakinaCorpus\DbToolsBundle\Attribute\Anonymize; 

#[ORM\Table(name: '`user`')]
class User
    private ?int $id = null;

    #[ORM\Column(length: 180, unique: true)]
    #[Anonymize(type: 'email')] 
    private ?string $emailAddress = null;

    // ...

With the above configuration, after you used console db-tools:anonymize on a backup file, all the user email addresses it contains will be replaced with hashed ones.

According to GDPR recommendations, sensitive data should never transit on an unsecured environment. Then, running the anonymization on our local development environment might not be compliant. We should therefore, for example, perform this task on the preproduction environment.

console db-tools:anonymize path/to/my_backup.dump

Once the command has succeeded, path/to/my_backup.dump will be fully anonymized. You will be free to download and restore it on your local environment without any security concerns.


We know that a slow anonymization process can be real pain. That's why a meticulous work has been carried out to make this operation as quick as possible.

Thanks to this work, the DbToolsBundle can now anonymize 1 million rows in less than 20s!

Use case 3 - Getting basic stats on your database without proper monitoring

In a small project, you can't always have a nice monitoring for your database. Often, all you have is a simple database client accessible through an SSH connection. In such case, getting stats frequently ends with copy/pasting big SQL queries in a shell prompt.

If this sounds familiar to you, try to launch:

console db-tools:stats

It will give you a bunch of nice stats about your database. And, honestly, this command alone could justify you install this bundle! ☺️
