Describe how you implemented data backup and recovery processes in your projects.

In projects, I implemented data backup and recovery processes as follows:

• Used built-in database tools, such as pg_dump and pg_restore for PostgreSQL, to create full or incremental backups.
• Set up automatic backup scheduling using cron or CI/CD systems.
• Stored backups in remote storage (e.g., AWS S3 or network drive) to protect against data loss in case of failures.
• Regularly tested recovery from backups to ensure their integrity and functionality.

Example command for creating a PostgreSQL backup:

pg_dump -U user -h host dbname > backup.sql

For recovery:

psql -U user -h host dbname < backup.sql

This approach minimizes the risk of data loss and allows quick system recovery after failures.
