Recommend a free large file transfer tool

When accessing overseas VPS hosts from mainland China, the file transfer speed is not ideal, often only a few tens of KB/second. Today I would like to recommend a free file transfer software to you – Raysync FTP Transfer.

Download and install:

Download the Raysync FTP transfer software: Go to the official website www.raysync.cn. The Raysync FTP transfer server supports Windows and Linux 64-bit systems. Most VPS are currently Linux systems. You can choose according to your own VPS server system. Just download the corresponding software package.

After downloading the Raysync FTP transfer software installation package, follow the official installation help and it will take about 10 minutes to complete the installation.

Two points to note:

• Attention should be paid to the release of VPS fire protection "unspeakable" ports. Raysync FTP needs to open 1 TCP port 8090 and 1 UDP port 32001 to the outside world. These two ports can also be modified on the background management page of Raysync FTP.
• After the installation is completed, pay attention to obtain the free activation code on the official website and activate it on the Web backend management page. If it is not activated, the transmission speed will be limited to 500KB/second.

Actual transmission effect test:

My test machine is Guangzhou Telecom’s 100Mbps bandwidth and 20Mbps uplink. Made a data transfer comparison using FTP:

It is not difficult to see from several test comparisons that the file transfer effect in overseas regions such as Europe, North America, and India is quite good, and machines with XEN/KVM/OpenVZ virtualization architecture can be used.

About activation code:

You can apply for a free 50Mbps activation code for up to 6 months on the official website of Raysync. After application, the activation code will be sent to the email address you filled in. I communicated with the official staff of Raysync, and they said that after the 6 months expires, you can continue to apply for a new activation code online, and you can continue to use it after reactivation. In other words, 50Mbps is free forever.

About the technical principle behind the high transmission speed of Raysync FTP:

1. After reading the official introduction of Raysync, Raysync FTP transmission is optimized at the transmission protocol level and uses UDP for reliable transmission encapsulation. The underlying protocol is called RaySync protocol, which is probably similar to the Google QUIC protocol.

2. Raysync FTP transmission is point-to-point, that is, it is transmitted directly from the client's computer to the VPS server, without forwarding through CDN nodes in the middle.

Evaluation summary:

• Raysync FTP transfer software is simple to install and easy to use, and can be installed and used by XEN/KVM/OpenVZ.
• The transmission effect from mainland China to VPS in various overseas regions (North America, Europe, India) is very good, and the improvement is very obvious. In my comparison here, there is a 20-60 times improvement.
• The 50Mbps free activation code can meet most people’s daily file transfer needs.
