Block-level sync: upload only what changed in a big file

When a big file changes a little, a sync client can send only the changed blocks of 8 to 64 MB. The server compares block fingerprints and copies the unchanged blocks inside the storage itself, so they never travel over your connection.

Bakit upload.am

Why block-level sync

Saves bandwidth

A 100 GB disk image that changes by 1 GB uploads about 1 GB, not 100 GB.

Fits growing files

Databases, mailboxes and logs that change in place or grow at the end.

Becomes a version

The new content becomes a file version, so you can go back.

Open protocol

A developer API in the public API reference.

upload.am kumpara sa karaniwang file storage service

Karamihan sa mga libreng file host ay isang bagay lang ang ibinibigay: isang link. Ang upload.am ay cloud storage na may built-in na backup, sync, at ligtas na pagbabahagi. Ito ang pagkakaiba sa feature na ito:

Sa libreng plan upload.am Karaniwang file host
Upload only changed blocks Kasama Wala
Server-side copy of unchanged blocks Kasama Wala
Result stored as a file version Kasama Limitado
Documented public API Kasama Limitado
Higit pa sa isang link para sa pagbabahagi ng file

Cloud file storage, backup, at sync sa isang libreng account

Ang upload.am ay isang hybrid: isang cloud storage service na mapagbabahaginan mo, isang backup service na nagpoprotekta sa iyong mga folder at larawan, at isang sync service na pinananatiling magkapareho ang iyong computer at cabinet. Isang login, isang storage, isang set ng mga link.

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.
