Why each option
Offsite data backups are the best way to facilitate recovery of data lost due to a cybersecurity incident, ensuring data availability even if primary systems are compromised or destroyed.
A Disaster Recovery Plan (DRP) outlines the process for recovery but doesn't inherently contain the data itself; offsite backups are the means for data recovery.
Offsite data backups provide a secure and isolated copy of data that can be restored in the event of primary data loss or corruption due to a cybersecurity incident. Storing backups offsite protects them from localized disasters or network-wide compromises, making them a highly reliable source for data recovery and ensuring business continuity.
Encrypted data drives protect data confidentiality but do not facilitate data recovery if the data itself is lost or corrupted due to an incident.
Removable storage media can be used for backups, but the "offsite" aspect is crucial for resilience against major incidents that could affect local storage.
