The Hugging Face Hub held over 30 PB of models and datasets in Git LFS repositories where every new checkpoint version was stored in full. Sequence the move to chunk-level deduplicated storage under live traffic, and say where the saving actually comes from.

Chunk-Level Deduplication
Splitting files into content-addressed pieces at boundaries chosen by the data itself, so repeated rewrites of a large artifact store only the bytes …
conceptRetrieval-Cost Trap
The failure where moving data to an archival tier saves storage cost and a scanning access pattern then spends more on retrieval than the tiering saved.
conceptStorage Costs
Storage is cheap per gigabyte and expensive in aggregate — controlled by retention and tiering rather than by unit price.
practiceStorage Lifecycle Policy
Automated rules that move objects between storage classes as they age, matching cost to the declining probability that data will be read.
