S3sync :: About

S3sync is an engineering tool for controlled S3-compatible data migration, built from DevOps engineer requirements for high-speed copying, reliable continuation after interruptions, and an interface that remembers humans use it.

Migration control panel

Create, monitor, and manage migration jobs from a single web dashboard.

S3-compatible sources

Configure S3 connections, validate access, and fetch bucket lists directly from the interface.

Resumable migration

Jobs are designed to continue reliably after stops, restarts, and operational interruptions.

Large bucket listing

We know the listing problem in buckets with 100M+ objects and build migration flow around it.

Agent-based S3 migration

Migrations run through user-controlled agents, keeping data movement close to your infrastructure.

Resource-aware execution

We try to use available network, CPU, and memory as productively as possible while respecting provider rate limits.

Smarter planning ahead

The roadmap includes more intelligent resource use and automatic migration planning with less operator involvement.

Operational visibility

Connection checks, error logs, runtime status, and recent errors are visible in the UI.

Public test access

The current demo plan includes up to 1 TB traffic per month while the service is in test mode.
