Routine maintenance, access review and recovery drills

Prerequisites and authority

Assign an operator and an authorized technical owner. Data-replacing recovery and updates require a maintenance window, preserved recovery point and known target.

Maintain security and recovery readiness

Review individual staff access, roles and active sessions regularly. Remove obsolete access through supported workflows and verify the outcome. Review integration/API credentials after personnel or vendor changes.

Check host/runtime updates separately from BryanNet release updates. Apply changes in a controlled window and verify connectivity afterward. Do not combine a database migration, router firmware change and VPN redesign into one unexplained intervention.

Inspect disk headroom, backup retention, failed off-site uploads and recovered file permissions. Confirm the recovery-key custodian can retrieve the correct key without relying on the failed host.

Conduct a restore drill in an isolated environment. Record time to restore, release/configuration prerequisites, missing files and acceptance results. A verified archive without a working restore drill does not prove recovery readiness.

Review router management firewall restrictions and VPN return routes. Avoid exposing database or RouterOS API ports for convenience. Temporary diagnostic access must be removed after use.

Review incident trends and recurring worker failures. Improve configuration, monitoring or code through the alignment backlog rather than normalizing repeated manual resets.

Daily weekly and monthly operator checklists supplies daily/weekly/monthly checks. Adjust frequency to workload while preserving clear ownership and evidence of completion.
