Oh man, that's the classic Friday afternoon nightmare! Here's what I'd do in that situation:

First, I'd take a deep breath and immediately notify the production manager about the backup situation - no sugarcoating. This is a safety and business continuity issue. I'd explain that running a weekend trial with outdated backups is like driving without a spare tire.

Next, I'd prioritize creating a current backup RIGHT NOW before anything else happens. Even if it means delaying the trial start by an hour or two, this is non-negotiable. According to best practices, PLC programs should be backed up at least annually, and always after any changes.

While the backup is running, I'd document everything: when the last backup was, what changes have been made since then, and the current risk assessment. I'd also check if there are any emergency procedures or interlocks that might have been modified.

Before approving the weekend trial, I'd want to verify that all safety systems are functioning properly and that the team running the trial knows exactly who to call if something goes wrong.

Honestly, this situation highlights why having a solid 'Friday afternoon protocol' is crucial - automated reminders, clear backup schedules, and proper communication channels can prevent these last-minute crises!
