Description: Backup copies are data copies made to prevent loss in case of failures. In the context of ETL (Extract, Transform, Load), backup copies are crucial to ensure that extracted and transformed data remains intact and available for later analysis. Backup copies are essential to protect data integrity and ensure service continuity across various systems and applications. These copies can be made in various ways, including full, incremental, or differential backups, depending on the specific needs of the environment and the amount of data to protect. Implementing effective backup strategies not only helps prevent data loss but also facilitates quick and efficient recovery in case of disasters, hardware failures, or human errors. In environments where large volumes of data are handled and complex calculations are performed, backup copies are fundamental to ensure that the results of simulations and analyses are preserved and can be recovered in case of any eventuality.
