How to use Media Library Storage Calculator
- Enter daily master and derivative growth on a consistent raw basis.
- Use retention that reflects deletion or archival policy.
- Review forecast capacity, copy count, access traffic, and annualized run rate.
Calculator guide
Understanding Media Library Storage Calculator
A media library combines large masters, derivatives, thumbnails, replicas, and a retention period that may be effectively permanent.
Calculation method
How the calculation works
Translate daily media library creation into retained raw volume, apply compression and replica count, project monthly growth, and reconcile current and forecast storage capacity and run-rate cost. Daily media GB times retention days creates the retained raw library; compression and copies determine stored capacity at each forecast point.
Media shelf
Arrange masters and derivatives across storage tiers
The visual separates new assets, retained masters, working derivatives, replicas, and forecast capacity.
Worked situations
Practical examples
- One master plus a working proxy may act like two stored copies if both remain online.
- Image thumbnails add many objects but relatively few bytes.
- Video masters can make a short retention change materially affect capacity.
Better inputs
Useful tips
- Separate masters, proxies, derivatives, and delivery caches.
- Use lifecycle tiers for rarely accessed masters.
- Track object counts as well as bytes for operational limits.
Before relying on the result
Limitations and common mistakes
- The model uses one compression ratio and one storage rate.
- Transcoding compute, CDN delivery, object requests, and cache storage are simplified.
- Permanent archives outlive the selected forecast horizon.
Reference
Key terms
- Master asset
- Highest-quality retained source file.
- Derivative
- Proxy, thumbnail, rendition, or delivery copy created from a master.
- Lifecycle tier
- Storage class selected according to access frequency.
Important note
Calculated from the entered technical values using the displayed model. Validate topology, workloads, capacity, security, redundancy, and observed performance before implementation.
Frequently asked questions
Should CDN cache count as a replica?
Only if it is persistent and separately billed in the modeled storage estate.
How do I model permanent retention?
Choose a meaningful planning horizon and recognize growth continues afterward.
Are object-request fees included?
Only through the entered monthly access and egress allowance.
