The R1Soft web site has great documentation on how to install their backup agent on Ubuntu here. The QuantaStor OS is built on top of Ubuntu Server LTS releases and is compatible with the packages available from R1Soft.
Here's a summary of the commands to run to install the agent on a QuantaStor appliance:
wget http://repo.r1soft.com/r1soft.asc apt-key add r1soft.asc apt-get update apt-get install serverbackup-enterprise-agent
