Review site documentation to confirm the DSN local system backup media is available and up-to-date prior to any software modification. If the DSN local system backup media is not available locally and up-to-date prior to any software modification, this is a finding.

Fix Text (F-67177r1_fix)
Implement and document DSN local system backup media onsite with the system. Ensure removable media is removed and stored off-site. Storing a copy on the system is highly recommended. Perform a system backup just prior to any system change, maintenance, or upgrade. If this is not feasible, the most recent weekly backup must be available for use.
