How to Estimate the Business Cost of Duplicate Cloud Files

Duplicate-file cost is often overstated because cloud plans bundle capacity and storage is only one component. The more defensible case may be migration duration, review burden, backup volume, search confusion, or the risk of acting on the wrong revision.

Team libraries need an owner and a decision trail. A byte-identical file may still be required in a separately permissioned workspace, under a retention rule, or as the target of a shared link.

Build a transparent model with current marginal storage cost, reviewed recoverable bytes, backup replicas, migration bandwidth, reviewer time, and incident history. Label assumptions and show conservative, expected, and high scenarios.

Pilot the workflow on a representative scope, record exceptions, and measure false positives before expanding. Business cleanup is safer as a governed series of batches than as a single drive-wide action.

Compare the savings with scan, review, communication, and recovery costs. Prioritize the cleanup when it also improves information quality or avoids a capacity purchase; defer low-value groups whose decision cost exceeds their benefit.

The exported plan should be useful outside the scanner: identify the account and scan, retained items, candidates, evidence, reviewer, and exceptions so another person can audit the decision.
