feat: create database backup on server shutdown

[dudantas]

Description

This update introduces a refined automatic database backup feature during the server shutdown process. The main improvements include:

1. Automatic Compression: The database backup is now always compressed using gzip, reducing disk space usage.

2. Backup Management: The system organizes backup files into folders named by date and automatically deletes backups older than 7 days. This ensures that the backup storage remains manageable over time without manual intervention.

The motivation behind these changes is to create a more efficient and reliable way of managing database backups, ensuring data safety while optimizing storage space usage. The feature can be highly useful for production servers, as it creates backups during shutdown and maintains them efficiently by automatically removing old backups.

Behaviour

Actual

On server shutdown, no database backup was created automatically, potentially putting the data at risk of loss. There was no effective mechanism for managing old backup files.

Expected

On server shutdown, a backup of the entire database is automatically created, including all tables and data types, ensuring data is always safeguarded. Backups are always compressed, and backups older than 7 days are automatically deleted.

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested

The database backup feature has been tested by:

• Running the server multiple times to ensure that backups are correctly created on each shutdown.
• Verifying the integrity of the SQL files by restoring the database from compressed backup files.
• Confirming that backups older than 7 days are properly deleted.
