The primary function of a backup and recovery tool is to ensure the protection and restoration of data in case of loss or corruption. These tools automate the process of creating backups, which are essential for safeguarding data against hardware failures, cyberattacks, and accidental deletion. Effective backup solutions offer features such as incremental backups, cloud storage options, and quick recovery processes to minimize downtime. By maintaining regular backups, organizations can ensure business continuity, comply with data retention policies, and mitigate the risks associated with data loss.
