Having both local and off-site backups ensures that if a disaster impacts the physical location of the business, such as a natural disaster, there will still be access to the operating system backups. Local backups allow for quick restoration to minimize downtime, while off-site backups provide additional security against localized incidents. Full backups ensure that the entire operating system is available for restoration, which is critical for business continuity. Incremental or differential backups might not always store the full state needed for a complete and rapid system recovery.
