The purpose of utilizing cloud disaster recovery services is to ensure business continuity by protecting data and applications from unexpected disruptions. These services allow organizations to store backups in the cloud, enabling quick recovery of critical systems in the event of disasters such as natural calamities, cyber-attacks, or hardware failures. By leveraging cloud resources, companies can minimize downtime and restore operations efficiently. Additionally, cloud disaster recovery solutions can be more cost-effective than traditional on-premises systems, allowing businesses to scale resources as needed.
