# TrilioVault for RHV Architecture

TrilioVault is following modern principles to provide a native, userfriendly, and powerful Backup & Recovery solution for RHV. It does not require any big Mediaservers or clients running on the VMs that are getting protected. 

TrilioVault architecture reflects these principles.

## TrilioVault Appliance

The TrilioVault Appliance is the controller of TrilioVault, called TVM.

The TVM is running and managing all Backup and Recovery Jobs.

During a Backup Job is the TVM:

* gathering the Metadata information generated of the VMs that are getting protected
* Writing the Metadata information onto the Backup Target
* Generating the RHV Snapshot
* Sending the data copy commands to the ovirt-imageio services

The TVM is available as qcow2 image and runs as VM on top of a KVM Hypervisor.

It is supported and recommended to run the TVM in the same RHV environment, that the TVM protects.

## RHV-Manager GUI integration

TrilioVault is natively integrating into the available RHV-M Web Gui, providing a new tab "Backup".

All functionalities of TrilioVault are accessible through the Web Gui.

The RHV-Manager GUI integration is getting installed using Ansible-playbooks together with the ovirt-imageio-proxy extension.

## Ovirt-imageio extensions

Ovirt-imageio is an RHV internal python service that allows the upload and download of disks into and out of RHV.

The default ovirt-imageio services only allow to move the disks through the RHV-M via https.

TrilioVault extends the ovirt-imageio functionality to provide movement of the disk data through NFS over the RHV Hosts themselves.

The ovirt-imageio extensions are getting installed using Ansible-playbooks.

## Backup Target

TrilioVault is writing all Backups over the network using the NFS protocol to a provided Backup Target.

Any system utilizing the NFSv3 protocol is usable.
