How Does it Work?

Resilio Connect runs as a file replication service on your Windows Servers and replaces DFS replication (DFSR) while maintaining compatibility with the DFS Namespace.
The solution is managed using a web-based interface and can also be controlled using a REST API or PowerShell.

Predictable Replication

Resilio Connect delivers predictable, near real-time replication of distributed file servers. Independent of the size of the file system it quickly detects file changes and starts replicating within seconds.

The centralized Management Console shows you details of the replication process across all servers. You can view DFSR replication status, audit logs from each server, and real-time completion ETA.

A granular notification system allows you to receive alerts through email and webhooks on any replication issues.

File Replication Flexibility

Resilio Connect gives you the flexibility to implement the workflow you need. It supports:

  • Two-way and one-way syncs

  • Pre-seeding of data

  • Ability to add and remove servers and replication jobs on the fly

Cloud Extensibility

Resilio Connect supports synchronization with all the major object storage providers. It allows you to go beyond on-prem file servers and sync/backup some or all of your data to the cloud. We support AWS S3, Azure Blob, Google Cloud Storage, IBM, Wasabi, Oracle, and any other S3-compatible object storage.

Efficient Error Recovery

Resilio Connect was built to be resilient and reliable. It uses simple data structures that are corruption-proof to keep an index of the file system. You’ll never have to rebuild a DFSR index or lookup a DFSR error ever again.

“Now we can retrieve information that is more complete, fulsome, and more robust because we have the ability to transmit large files faster across the internet”
— Jerry Evans, President & CEO of Nia Technologies


Resilio Connect leverages custom UDP based WAN optimized protocol to deliver high-performance transfer between sites. That is combined with block-level peer-to-peer protocol to simultaneously transfer files to several servers. Resilio Connect, depending on the infrastructure, delivers 2-10x times faster replication speed than DFSR.

Well, there might be a better way. For us, that's Resilio.” — Brady Small, Sr. Production Engineer Sports Central Systems.
