How it works
The client splits the file into blocks and sends fingerprints. The server answers which blocks it already has and which are new. Only new blocks are uploaded; the rest are copied inside the storage. The result is a new file version.
This is a developer API: it is meant for backup and sync tools, not for clicking in the browser. Block sync is included in Premium GOLD, Business and Enterprise. See plans and pricing.
