Backup solutions ensure data integrity by creating copies of data to safeguard against loss or corruption. These solutions typically involve regular and automated backups, which can be stored on cloud services or external drives. Techniques like versioning, where multiple historical backups are retained, allow for recovery of earlier data states if needed. Moreover, established protocols for data verification check that backups are accurate and usable. By implementing effective backup strategies, organizations can ensure business continuity, protect sensitive information, and recover efficiently from unexpected incidents.
