Before you start

What this tool does

A useful backup plan starts with the data you actually need to restore. Estimate growth over time, add a separate allowance for historical versions, and reserve working space. Extra copies are counted separately.

The working

Dataset = current GB + annual growth GB × years. Per-copy capacity = dataset × (1 + version allowance) × (1 + headroom).

Where the estimate stops

This is a logical-capacity estimate. Compression, deduplication, retention rules, metadata and service quotas vary. Capacity alone does not prove a backup can be restored.

How we handle data

Understand the result

A little context goes a long way.
