Rule 7: Keep backups AI can’t reach

Limit what AI can delete, and test the restore.

What it means

If an AI deletes or changes the wrong things, it’s the same situation as an upset employee doing it, and the same two things protect you. Limited access keeps the damage small, and backups the AI can’t touch mean you can restore and carry on.

A simple example

In July 2025, an AI coding agent deleted a company’s live database, ignoring an instruction to freeze the code. The instruction had only been typed into the chat, so nothing in the agent’s access enforced it. The data was recovered (The Register).

IT, explainedWhen did you last test a restore?

Do it yourself

  • Keep backups outside the AI’s reach, in a separate account or service it can’t log in to.
  • Know your built in undo. Microsoft 365 and Google Workspace both keep deleted files and older versions for a limited time, so find out how long yours keeps them.
  • For longer or more precise recovery, use a separate backup service, with copies that can’t be altered.
  • Write down how long a restore takes, so you know how long you’d be without the data.

How to check

Restore a test folder to a point before some deliberate edits, and time it.

What that misses

Built in undo only goes back a limited time. A backup that’s never been test restored may fail when you need it.

What we do for you

We back up your Microsoft 365 or Google data to a separate service and test restores, so you know how long one takes.
