Remote Backup: How to Set up Your Own using BackupChain®

Set up your own Online Backup over the Internet

You can connect two computers over the Internet using BackupChain. Each PC needs to be set up as the recipient of the other PC's backup. If you want to connect more than two PCs, you could create a 'star' network where one PC is at the center and receives all backups. All other PCs send their backup to the central PC.

This article illustrates typical online and remote data backup scenarios and gives simple instructions to set up a secure remote FTP backup system using BackupChain's built-in FTP server and DriveMaker Plus, which allows the remote site to be mounted as a drive letter.

A Typical Setup of A Remote Backup System

With BackupChain you can easily set up your own offsite or online remote backup system. You can either send your virtual machines, databases, and other files via FTP to another BackupChain instance, or to a standard FTP server on the web. Note that you can connect servers and workstations via the Internet but also via a Virtual Private Network (VPN). If you have a network share access over your WAN or local network, you can back up client PCs from the server by having the server pull the files from the client workstations. Alternatively, clients can send their files as needed to the remote backup server.

Example: Backup Your Office Server Data to your Home Server

First, you need to set up the built-in FTP server that ships with BackupChain on your home PC or server. Select a main FTP port, such as 21, and configure your home Internet router to forward this port number and the port range 8192 to 16384 to your home server. You can set up multiple FTP users with passwords as necessary, see this article: How to Set up the Built-in FTP Server. Instructions on how to configure your home Internet router depend on the exact router model you have and can be found in the router's user's manual or online help. For security reasons, it is recommended to use a non-standard port for FTP (other than 21) to hide the existence of a FTP server from the public. Also, some Internet Service Providers (ISPs) block port 21.

Home users only: Unless you have a static IP address, you will need to obtain an address from a dynamic DNS provider, such as or, for free. (Note: FastNeuron Inc. is not affiliated with these services and companies.) You need to install a small client tool that these companies provide, which will update your IP address and map a unique name to your dynamic IP address, for example: This address enables you to access your home PC from the Internet without knowing its actual IP address.

On your office server, install BackupChain, select the folders you wish to back up, and select FTP as a remote backup target. Enter the address, port number, user name, and password and you are ready to go!

You may also want to protect your data by encrypting it. BackupChain offers military-strength AES 256 encryption, which is FIPS and HIPAA compliant and recommended to protect all critical information.

In addition, the built-in BackupChain FTP server protects from hacker attacks by banning IPs for several minutes after three consecutive failed login attempts. If you have already set up a FTP server at your home, or you are paying for an online hosting service, you can also use your existing FTP server arrangement with BackupChain.

How to Back up Two Servers to Each Other Without Backup Media

On a local network

On a local LAN or VPN, simply create a network share on both computers and give full permissions. Then install BackupChain on both PCs and select the 'Network Folder' backup target. Enter the other computer's network share name, user, and password information. Now each PC will back up on the other's hard drive!

Via the Internet

Set up the FTP server built-in to BackupChain as described in the previous example on each computer. Then select FTP backup target and enter the other PC's address, port, and user/password information. Ensure port forwarding is switched on and working in your router.

Tip: To check that your routers are configured correctly and that BackupChain's FTP server is running as expected, open your browser and point it to the FTP address of your PC and then the other PC you like to connect to:, where 28374 would be your own port number. The browser should display a dialog box asking for your user name and password. After entering the information you will see a directory listing of your backup files on the other computer via FTP.
