Backup Pager Fires After Every Run

The nightly backup logs a finished archive every run, yet BackupFailure has paged the night shift three nights running.

Briefing

Since last week's config migration, the nightly backup has logged a finished archive and then paged anyway.

The night shift started deleting ERROR lines from backup.log to quiet it, and audit has now told everyone to stop.

The fix is yours to find: hints, the recovery checks and the debrief unlock inside the incident.

How it plays

  1. 01

    Get paged

    The alert fires and the clock starts. Read the page and the briefing.

  2. 02

    Investigate

    Work in a simulated shell with realistic output: logs, configs, services.

  3. 03

    Fix it

    Change the system the way you would in production. Hints are there if you get stuck.

  4. 04

    Prove it

    Automated checks verify the recovery, then the debrief explains what happened.

Your pager is ready.
