1.2.4 Acronis Backup Advanced for vCloud architecture
Acronis Backup Advanced for vCloud consists of multiple components that need to be installed on
separate machines.
Components of Acronis Backup Advanced for vCloud
A typical installation includes at least two virtual machines located in the vCloud management cluster
and a number of virtual appliances running in the vCloud resource group.
The following components run in the vCloud resource group:

Agents for VMware, formerly known as Agents for ESX(i), run as virtual appliances.
Agent for VMware performs backup and recovery of ESX(i) virtual machines without installing
agents into the guest systems.
The following components run in the management cluster:

Management Server needs to be installed on a virtual machine running Windows.
The management server integrates with vCenter Server (the one that is allocated for the
resource group), deploys Agents for VMware, and manages backup and recovery.
The management server stores its configuration, logs and statistics in Microsoft SQL databases.
The databases can be attached to the SQL Server Express instance that is installed by default with
the management server, or to any other SQL Server instance accessible by the management
server.

Agent for vCloud runs on a Linux virtual machine, which also serves as the web server. The agent
is delivered as an Open Virtualization Format (OVF) template.
Agent for vCloud provides a graphical user interface to the users. The agent queries vCloud
Director for the list of users who can log in to the service and the list of virtual machines. Based
on the users' choices, the agent instructs the management server when and how to back up the
selected virtual machines. The agent retrieves the protection statuses of virtual machines directly
from the management server database. The agent also generates reports about the backup
service usage.
Software that is necessary for using Acronis Backup Advanced for vCloud
vCloud users interact with Acronis Backup Advanced for vCloud by using a web browser. To log in to
the backup service, they use the same credentials as they use to log in to vCloud Director. The web
browser connects to the agent's web server and displays the information that the agent provides.
The amount of information depends on the user rights in vCloud Director.
