Laravel-backup: Backup Multitenant DBS

[rylxes]

is there a way to backup multi tenant databases, keeping in mind that there is only one database connection

[atymic]

It depends how your environment is configured.
Are there multiple databases sharing one connection, or are all tables in one database?

Can you post your config?

atymic... I too faced the similar problem... I have multiple databases sharing one connection...

Hey guys.
So, I had the same problem in the past and to solve this I made this code:

I have a table with the list of all my clients in a "main" bank with the client name and the database name of it.

$company = (new Company())->all();

So I make a foreach with each client and initiate the connection with his bank and I make the call to the artisan to run the backup: run for this client.

foreach($company as $comp){

           \Config::set('database.connections.main.database',$comp->data_base); 
              //$comp-data_base is name of my client database.
           \DB::reconnect('main'); 
             // name of my connection on config/database.php**
            $this->call('backup:run');

}

I hope this helps.

For Hyn\MultiTenant 5.4, to do backups of the entire app and all registered tenant databases I created the following custom command which calls a custom BackupJobFactory which overrides the default factory which only does one database, and instead calls a custom TenantDbSelector which loops through and processes all the tenant dbs.

Feel free to use it for inspiration for your own situation.

namespace App\Console\Commands;

use App\Services\BackupJobFactory;
use Exception;
use Spatie\Backup\Commands\BackupCommand as SpatieBackupCommand;
use Spatie\Backup\Events\BackupHasFailed;

class BackupCommand extends SpatieBackupCommand
{

    protected $signature = 'backup:tenants {--disable-notifications}';

    public function handle()
    {
        consoleOutput()->comment('Starting backup...');

        $disableNotifications = $this->option('disable-notifications');

        try {
            $backupJob = BackupJobFactory::createFromArray(config('backup'));

            if ($disableNotifications) {
                $backupJob->disableNotifications();
            }

            $backupJob->run();

            consoleOutput()->comment('Backup completed!');

        } catch (Exception $exception) {
            consoleOutput()->error("Backup failed because: {$exception->getMessage()}.");

            if (! $disableNotifications) {
                event(new BackupHasFailed($exception));
            }

            return 1;
        }
    }
}

<?php

namespace App\Services;

use Spatie\Backup\BackupDestination\BackupDestinationFactory;
use Spatie\Backup\Tasks\Backup\BackupJob;
use Spatie\Backup\Tasks\Backup\BackupJobFactory as SpatieBackupJobFactory;

class BackupJobFactory extends SpatieBackupJobFactory
{
    public static function createFromArray(array $config): BackupJob
    {
        return (new BackupJob())
            ->setFileSelection(static::createFileSelection($config['backup']['source']['files']))
            ->setDbDumpers(
                static::createDbDumpers($config['backup']['source']['databases'])
                ->merge(TenantBackupDbSelector::getTenantDatabaseConnections())
            )
            ->setBackupDestinations(BackupDestinationFactory::createFromArray($config['backup']));
    }
}

<?php

namespace App\Services;

use Hyn\Tenancy\Models\Website;
use Illuminate\Support\Arr;
use Illuminate\Support\Collection;
use Spatie\Backup\Tasks\Backup\DbDumperFactory;
use Spatie\DbDumper\Databases\MySql;
use Spatie\DbDumper\DbDumper;

class TenantBackupDbSelector extends DbDumperFactory
{
    public static function getTenantDatabaseConnections(): Collection
    {
        $websites = Website::all();

        return $websites->map(function ($tenant) {
            return self::createConnection($tenant->uuid);
        });
    }

    public static function createConnection(string $tenantDbName): DbDumper
    {
        $dbConfig = config('database.connections.' . config('tenancy.db.system-connection-name', 'system'));

        $dbDumper = static::forDriver($dbConfig['driver'])
            ->setHost(Arr::first(Arr::wrap($dbConfig['host'] ?? '')))
            ->setDbName($tenantDbName)
            ->setUserName($dbConfig['username'] ?? '')
            ->setPassword($dbConfig['password'] ?? '');
        if ($dbDumper instanceof MySql) {
            $dbDumper->setDefaultCharacterSet($dbConfig['charset'] ?? '');
        }
        if (isset($dbConfig['port'])) {
            $dbDumper = $dbDumper->setPort($dbConfig['port']);
        }
        if (isset($dbConfig['dump'])) {
            $dbDumper = static::processExtraDumpParameters($dbConfig['dump'], $dbDumper);
        }

        return $dbDumper;
    }
}

I also enabled encryption using the approach suggested by @skollro here: https://simonkollross.de/posts/creating-encrypted-backups-of-laravel-apps
(Granted, even on L5.8.28 I had to register the event in my EventServiceProvider, but maybe that's because I had other events in there I had to register already. I'll investigate that at some point.)
