This package intends to keep backups of your .env file. It checks for changes in .env file periodically on the given interval and creates a backup in your root folder in case of change.

Install the package using composer
composer install hpez/dotenvbackup

And publish the config file using
php artisan vendor:publish --tag=config

You can set the interval for checking the env file for changes in the config file. By default, it checks for changes every minute.
The format is same as the format for cron jobs e.g.

Every minute: * * * * *
Every five minutes: */5 * * * *
Every hour at minute 0: 0 * * * *

You can use websites like this or this to generate one.
You can also customize the backup directory in the config file which defaults to your projects root directory retrieved from laravel's base_path() function.

Once you install the package it will automatically check for changes in .env file and create backups in the root of your project. It will also gitignore the created backups.
