ii. Provisioning of a disaster recovery system setup, preferably in a separate geographical location.
iii. Detailed data and system backup/restoration action-plan and procedures to make sure that minimal data loss occurs even in case of major disaster.
iv. Pre-defined procedure of data recovery and restoration using backup data or other sources.
