TrilioVault License

It is possible to directly provide the TrilioVault Appliance with the license file that is going to be used by it.

It is not necessary to provide the License file directly through the configurator. It is also possible to provide the license afterwards through the TrilioVault License tab in the TrilioVault dashboard.

The TrilioVault License tab can also be used to verify and update the currently installed license.

Submit and Configuration

After filling out every block of the configurator, hit the submit button to start the configuration.

The configurator asks one more time for confirmation before starting.

Stay patient during the configuration, as this may easily take a few more minutes.

After the configurator has succeeded or failed, is the Ansible playbook shown. Use the possibilities to expand and collapse each task for troubleshooting failed configurations.

To upgrade TrilioVault it is necessary to uninstall the old version of TrilioVault and install the new version.

This is done in a few easy steps.

1. Uninstall the old ovirt-imageio extensions

2. Delete or shutdown the old TrilioVault Appliance

3. Upload the qcow2 image of the new TrilioVault Appliance

   (It might be necessary to verify the connection of the ovirt-imageio-proxy again)

4. Spin up the new TrilioVault Appliance

5. Configure the TrilioVault Appliance

6. Install the new ovirt-imageio extensions

TrilioVault extends the ovirt-imageio services running on the RHV-Manager and the RHV hosts, to provide the parallel download of disks from multiple RHV hosts.

The imageio extensions are getting installed automatically using Ansible playbooks provided on the TrilioVault Appliance.

Preparing the inventory files

Ansible playbooks are working with inventory files. These inventory files contain the list of RHV-Hosts and RHV-Managers and how to access them.

To edit the inventory files, open the following files for the server type to add.

For the RHV hosts open: /opt/stack/imageio-ansible/inventories/production/daemon For the RHV Manager open: /opt/stack/imageio-ansible/inventories/production/proxy

Using password authentification

The first supported method to allow Ansible to access the RHV hosts and the RHV Manager is the classic user password authentification.

To use password authentification edit the files using the following format:

<Server_IP> ansible_user=root password=xxxxx

One entry per RHV Host in daemon file and one entry per RHV Manager in the proxy file are required.

Using passwordless authentification (SSH keys)

The second supported method to Allow Ansible to access the RHV hosts and the RHV Manager is utilizing SSH keys to provide passwordless authentification.

For this method, it is necessary to prepare the TrilioVault Appliance and the RHV Cluster Nodes as well as the RHV Manager.

The recommended method from Trilio is:

1. Use ssh-keygen to generate a key pair

2. Add the private key to /root/.ssh/ on the TrilioVault Appliance

3. Add the public key to /root/.ssh/authorized_keys file on each RHV host and the RHV Manager

Once the TrilioVault Appliance can access the nodes without password, edit the inventory files using the following format:

<Server_IP> ansible_user=root

One entry per RHV Host in the daemon file and one entry per RHV Manager in the proxy file are required.

Starting the installation

To install the ovirt-imageio extensions go to:

/opt/stack/imageio-ansible

Depending on the method of authentification prepared in the inventory files, different commands need to be used to start the Ansible playbooks.

Using password authentification

To call the Ansible playbooks when the inventory files use password authentification run.

For RHV Hosts: ansible-playbook site.yml -i inventories/production/daemon --tags daemon For RHV Manager: ansible-playbook site.yml -i inventories/production/proxy --tags proxy

Using passwordless authentification (SSH keys)

To call the Ansible playbooks when the inventory files use passwordless authentification run.

For RHV Hosts: ansible-playbook site.yml -i inventories/production/daemon --private-key ~/.ssh/id_rsa --tags daemonFor RHV Manager:ansible-playbook site.yml -i inventories/production/proxy --private-key ~/.ssh/id_rsa --tags proxy

TrilioVault for RHV, by Trilio Data, is a native RHV service that provides policy-based comprehensive backup and recovery for RHV workloads. The solution captures point-in-time workloads (Application, OS, Compute, Network, Configurations, Data, and Metadata of an environment) as full or incremental snapshots. A variety of storage environments can hold these Snapshots, including NFS and soon AWS S3 compatible storage. With TrilioVault and its single-click recovery, organizations can improve Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO). TrilioVault enables IT departments to fully deploy RHV solutions and provide business assurance through enhanced data retention, protection, and integrity.

With the use of TrilioVault’s VAST (Virtual Snapshot Technology), Enterprise IT and Cloud Service Providers can now deploy backup and disaster recovery as a service to prevent data loss or data corruption through point-in-time snapshots and seamless one-click recovery. TrilioVault takes point-in-time backup of the entire workload consisting of computing resources, network configurations, and storage data as one unit. It also takes incremental backups that only capture the changes made since the last backup. Incremental snapshots save time and storage space as the backup only includes changes since the last backup. The summarized benefits of using VAST for backup and restore are:

1. Efficient capture and storage of snapshots. Since our full backups only include data that is committed to storage volume and the incremental backups include changed blocks of data since the last backup, our backup processes are efficient and storages backup images efficiently on the backup media.

2. Faster and reliable recovery. When your applications become complex that snap multiple VMs and storage volumes, our efficient recovery process brings your application from zero to operational with the click of a button.

3. Reliable and smooth migration of workloads between environments. TrilioVault captures all the details of your application, and hence our migration includes your entire application stack without leaving anything for guesswork.

4. Through policy and automation, lower the Total Cost of Ownership. Our role driven backup process and automation eliminates the need for dedicated backup administrators, thereby improves your total cost of ownership.

TrilioVault is a pure software solution and is composed of 4 elements:

1. TrilioVault Appliance (Virtual Machine)

2. TrilioVault RHV-M Web-GUI extension

3. TrilioVault ovirt-imageio-proxy extension

4. TrilioVault ovirt-imageio-daemon extension

System requirements TrilioVault Appliance

The TrilioVault Appliance gets delivered as a qcow2 image, which gets attached to a virtual machine.

Trilio supports only KVM based hypervisors and recommends to use the RHV Cluster as the hoster for the TrilioVault Appliance.

The recommended size of the VM for the TrilioVault Appliance is:

The qcow2 image itself defines the 40GB disk size of the VM.

System requirements TrilioVault ovirt-imageio extension

TrilioVault is extending the ovirt-imageio-proxy service running on the RHV-Manager and ovirt-imageio-daemon running on the RHV-Hosts.

These extensions do not have any hardware related requirements, but they require specific versions of the ovirt-imageio services.

Please check the Support Matrix for further information.

TrilioVault 3.6 is the second release of TrilioVault for Red Hat Virtualization.

It is aimed to provide basic Backup and Recovery for Red Hat Virtualization 4.3.x. The full requirements can be found here.

The following functionalities are included in TrilioVault 3.6:

TrilioVault for RHV integrates tightly into the RHV environment itself. This integration requires preparation before the installation starts.

Installing Redis

TrilioVault is extending the ovirt-imageio services running on the RHV Manager and the RHV Hosts to allow the parallel disk transfer from multiple RHV-Hosts at the same time.

This extension is using a task queue system, Python Celery.

Python Celery requires a message broker system like RabbitMQ or Redis. TrilioVault uses the Redis message broker.

RHV does not include Redis, so installation is necessary.

The following steps install Redis:

1. Add the Fedora EPEL Repository# yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

2. Install Redis # yum install redis

3. Start Redis # systemctl start redis.service

4. Enable Redis to start on boot # systemctl enable redis

5. Check Redis status # systemctl status redis.service

Enabling Disk Upload through RHV Manager

Trilio delivers the TrilioVault Appliance as a qcow2 image.

Trilio supports that the TrilioVault Appliance is running on the same RHV Cluster it protects.

Uploading the qcow2 to the RHV Datastore is easy, but depending on the RHV usage so far, it might require the installation of additional certificates.

Verify the connection to the ovirt-imageio-proxy

RHV is using the ovirt-imageio-proxy service to upload and download images, snapshots, and disks through the RHV Manager.

The following steps verify the connection to the ovirt-imageio-proxy service.

1. Log in to the administrative portal of the RHV Manager

4. Click Test Connection

Install the ovirt-engine certificate

When the Test-Connection to the ovirt-imageio-proxy is failing, a usual reason is the client system mistrusting the RHV-M due to a missing certificate.

The RHV-M does have two certificates, which can both be required to access the ovirt-imageio-proxy.

The first certificate is directly available for download from the error message in the window. The below URL shows the general path to the certificate. The downloaded certificate is the root certificate for the certificates used by the ovirt-imageio-proxy.

https:///ovirt-engine/services/pki-resource?resource=ca-certificate&format=X509-PEM-CA

Download and install this certificate according to the clients operating system and browser used.

Test the connection to the ovirt-imageio-proxy again after installation.

The second certificate is the actual certificate of the ovirt-imageio-proxy shown to the client system upon connection. The download is only possible from the RHV-M host system directly. The usual location of the certificate is:

/etc/pki/ovirt-engine/certs/imageio-proxy.cer

Install the certificate according to the client's operating system and browser used.

Test the connection to the ovirt-imageio-proxy again after installation.

Uploading the TrilioVault VM qcow2 disk to RHV

The TrilioVault VM qcow2 image is a full operating system disk, that is getting attached to a VM running on the RHV-Cluster.

To be able to spin up the TrilioVault VM, upload the qcow2 disk into the RHV datadomain.

The following procedure uploads the qcow2 disk:

3. Fill out the presented form and choose the path to the qcow2 image on the client system

4. Click OK to start the upload

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.

After the installation and configuration of TrilioVault for RHV did succeed the following steps can be done to verify that the TrilioVault installation is healthy.

Verify the TrilioVault Appliance services are up

TrilioVault is using 3 main services on the TrilioVault Appliance:

• wlm-api

• wlm-scheduler

• wlm-workloads

Those can be verified to be up and running using the systemctl status command.

systemctl status wlm-api

Verify API connectivity from the RHV-Manager

The RHV-Manager is doing all API calls towards the TrilioVault Appliance. Therefore it is helpful to do a quick API connectivity check using curl.

The following curl command lists the available workload-types and verfifies that the connection is available and working:

curl -k -XGET https://30.30.1.11:8780/v1/admin/workload_types/detail -H "Content-Type: application/json" -H "X-OvirtAuth-User: admin@internal" -H "X-OvirtAuth-Password: password"

Verify the ovirt-imageio services are up and running

TrilioVault is extending the already exiting ovirt-imageio services. The installation of these extensions does check if the ovirt-services come up. Still it is a good call to verify again afterwards:

On the RHV-Manager check the ovirt-imageio-proxy service:

systemctl status ovirt-imageio-proxy
######
● ovirt-imageio-proxy.service - oVirt ImageIO Proxy
   Loaded: loaded (/usr/lib/systemd/system/ovirt-imageio-proxy.service; enabled; vendor preset: disabled)

   CGroup: /system.slice/ovirt-imageio-proxy.service
           └─1834 bin/python proxy/ovirt-imageio-proxy

On the RHV-Host check the ovirt-imageio-daemon service:

systemctl status ovirt-imageio-daemon
######
● ovirt-imageio-daemon.service - oVirt ImageIO Daemon
   Loaded: loaded (/usr/lib/systemd/system/ovirt-imageio-daemon.service; enabled; vendor preset: disabled)

Verify the NFS Volume is correctly mounted

TrilioVault mounts the NFS Backup Target to the TrilioVault Appliance and RHV-Hosts.

To verify those are correctly mounted it is recommended to do the following checks.

First df -h looking for /var/triliovault-mounts/<hash-value>

df -h
