Database Storage Downsizing

Stop Paying for Database Storage

You Don't Actually Use

Managed databases keep charging for allocated storage even after cleanup. Existing tools show the waste, but they do not tell you what is safely reclaimable or how to shrink it without a brittle DBA project. SelfHost identifies reclaimable storage, estimates the savings, and gives your team a provider-aware downsizing plan with explicit downtime and migration tradeoffs.

What you are actually paying for

For 30 GB actual data, 500 GB allocated.

What you're actually fighting against

Most tools help you notice the waste. You need help deciding whether it is reclaimable and how to shrink it safely.

Existing Tools

  • FinOps tools: Great at visibility, but stop at "you are overspending"
  • AWS/GCP/Azure docs: AWS and GCP have native paths with important constraints; Azure PostgreSQL still requires a migration-style workaround
  • DBA runbooks: Manual, fragmented, and hard to trust without deep provider knowledge
  • Result: Teams keep paying for wasted storage because acting feels riskier than waiting
Tomorrow

After SelfHost

  • Reclaimable storage estimate in dollars and GB
  • Shrink readiness result: shrink now, wait, or unsafe
  • Provider-aware path recommendation: native shrink, blue/green, or guided migration
  • Result: A clear business case and a safer decision before touching production

How SelfHost is planning to solve this

Three layers. Every signal reduces execution risk.

Storage Waste Detection

Reclaimable Waste Analysis

  • Measure allocated vs used vs realistically reclaimable storage
  • Separate true reclaimable waste from normal growth, retention, WAL/binlog buildup, and temporary spikes
  • Translate waste into monthly and annual savings potential
