Title

The DSN local system backup media must be available and up-to-date prior to any software modification. (Cat II impact)

Discussion

Site staff must ensure backup media is available and up-to-date prior to software modification that could cause a significant disruption to service if the new software is corrupted. Backup media will be available to site personnel prior to any software upgrades or major provisioning changes. This will enable site personnel to recover the DSN system in case of system failure under newly introduced software or major changes.

Check Content

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

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.
