Enforce Drive quota policy with scheduled sweeps

Automate periodic checks and clean-ups of Drive storage usage across a domain using a delegated service account.

The problem

Drive storage quotas are routinely exceeded by users who ignore warnings, leading to overage fees or blocked uploads. Manual enforcement is infeasible at scale and often misses shared or orphaned files.

How it works

  1. On a schedule, enumerate all users via the Admin SDK.
  2. For each user, impersonate and list their Drive files and usage.
  3. Identify those over quota and apply policy actions (notify, move, delete, etc).
  4. Log actions taken and update an audit record for compliance.
  5. Report summary statistics to admins or stakeholders.

What changes

Drive storage limits are enforced consistently and automatically, with auditable action history and reduced risk of surprise overages.

The trap in this one. The Drive API's file list endpoint (files.list) is eventually consistent: recent deletes or ownership transfers may not be reflected for several minutes, causing quota calculations to be stale or incorrect if you sweep too frequently. Relying on immediate consistency can result in users being penalised for files they've just deleted, or files being missed from enforcement runs. Always design for lag and recheck before taking irreversible actions.

Questions people ask

Can I enforce quotas on shared drives as well?

Yes, but shared drives require separate enumeration and their file ownership rules differ. Handle users and shared drives distinctly in your logic.

How often should sweeps run?

Daily or weekly is typical. More frequent runs risk acting on stale data due to Drive API consistency delays.

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.
