Enforce Drive storage quotas on a schedule

Identify and act on users who exceed Drive storage limits by scanning usage periodically and triggering clean-up or escalation.

The problem

Drive storage overruns are only surfaced when users complain or uploads fail. By the time enforcement is triggered, remediation is urgent and disruptive.

How it works

  1. Schedule a recurring job for the delegated service account to pull user storage usage from the Admin SDK Reports API.
  2. Identify users over quota and fetch their largest Drive items using the Drive API.
  3. Notify or take action (e.g., move items, alert user, or escalate) based on policy.
  4. Log actions and exceptions for audit and review.

What changes

Quota breaches are discovered and addressed before they cause user interruptions or emergency clean-ups.

The trap in this one. The Reports API lags by up to 24 hours, so a user can exceed their quota and continue uploading until the next update. Deleting files via the Drive API does not instantly reclaim quota—actual usage only drops once items are expunged from the user's trash, which is not immediate and may take days unless purged explicitly.

Questions people ask

Can I get real-time Drive usage per user?

No, the Reports API only updates daily. Drive API does not return total usage directly for users, so you must rely on the delayed report.

Does deleting files immediately free up user quota?

No. Files go to trash and only count as freed space after being permanently deleted. You may need to explicitly empty trash for timely enforcement.

Want this built?

This is a pattern we run in production. We will set up the delegation and build this on top of it — $500 per hour, most of it working the same day.
